Dictionary Definition and Examples

A dictionary is a reference book or online resource containing an alphabetical list of words, with the information given for each word. Etymology:Â  From the Latin, to say Examples and Observations S.I. HayakawaThe writing of a dictionary . . . is not a task of setting up authoritative statements about the true meanings of words, but a task of recording, to the best of ones ability, what various words have meant to authors in the distant or immediate past. The writer of a dictionary is a historian, not a lawgiver. If, for example, we had been writing a dictionary in 1890, or even as late as 1919, we could have said that the word broadcast means to scatter (seed, for example), but we could not have decreed that from 1921 on, the most common meaning of the word should become to disseminate audible messages, etc., by radio transmission. To regard the dictionary as an authority, therefore, is to credit the dictionary writer with gifts of prophecy which neither he nor anyone else possesses. In choosing our words when we speak or write, we can be guided by the historical record afforded us by the dictionary, but we cannot be bound by it. Looking under a hood, we should ordinarily hav e found, five hundred years ago, a monk; today, we find a motorcar engine.Stephen FryeA dictionary is an observatory, not a conservatory.R.L. Trask[T]he familiar notion that a word of English exists only if it is in the dictionary is false. A word exists if people use it. But that word may fail to appear in a particular dictionary published at a particular time because it is too new, or too specialized, or too localized, or too much confined to a particular social group to make it into that edition of the dictionary.Thomas JeffersonDictionaries are but the depositories of words already legitimated by usage. Society is the work-shop in which new ones are elaborated. The First English Dictionary David WolmanMany people mistakenly credit [Samuel] Johnson with writing the first English dictionary. That achievement belongs to a man named Cawdrey, who, 150 years before Johnson, published A Table Aphabetical. It was only 144 pages and defined some 2,500 dificult words; the rest people were just supposed to know. With its emphasis on boosting vocabulary, Cawdreys book is a lot like modern-day titles that help you pump up your word aresenal before attacking the SAT or waging war in the corporate world. Dictionaries and Usage Steven PinkerAlthough dictionaries are powerless to prevent linguistic conventions from changing, this does not mean . . . that they cannot state the conventions in force at a given time. That is the rationale behind the American Heritage Dictionary’s Usage Panel--which I chair--a list of 200 authors, journalists, editors, academics, and other public figures whose writing shows that they choose their words with care. Every year they fill out questionnaires on pronunciation, meaning, and usage, and the Dictionary reports the results in Usage Notes attached to entries for problematic words, including changes in repeated ballotings over the decades. The Usage Panel is meant to represent the virtual community for whom careful writers write, and when it comes to best practices in usage, there can be no higher authority than that community. The Limitations of Dictionaries Keith Denning[E]ven the largest dictionaries cant capture every possible word in the language. The number of possible word combinations of word elements like pre-, pter, and scope and the innumerable amount of speaking and writing done in English require that dictionary editors restrict themselves to listing only the most frequent words in a language, and even then, only those used over a substantial period of time. Dictionaries are therefore always at least slightly out of date and inaccurate in their descriptions of the languages stock of words. In addition, the use of many words is restricted to specific domains. For example, medical terminology involves a tremendous number of words unfamiliar to those outside the medical community. Many of these terms never enter general dictionaries of the language and can only be found in specialized medical dictionaries.David Skinner[M]y recent affair with lexicography has left me certain of a couple of things.One is that no dictionary contain s every word in the language. Even an unabridged dictionary is, well, abridged. The sciences, medicine and technology generate gobs of words that never make it into a dictionary; numerous foreign words that appear in English-language contexts are left out. A great many words are invented all the time, whether for commercial reasons or to amuse one’s friends or to insult one’s enemies, and then they simply vanish from the record.Another is that dictionary users and dictionary makers sometimes have very different notions of what a dictionary is for. One may think of it as a legal code for language; the other considers it a very partial report. One wants unambiguous answers about spelling and meaning and grammar and usage; the other aims for neutrality, and the more serious he or she is, the more wary the person is of imposing his or her own notions of good English on the language itself.​ Advantages of Online Dictionaries R.L.G.Macmillan, a publishing company, has announced that it will no longer print dictionaries. And yet it has announced this with a tone not of sadness, but excitement: exiting print is a moment of liberation, because at last our dictionaries have found their ideal medium. Michael Rundell, the editor-in-chief, makes a compelling case. Updating the print edition takes five years, while new words are constantly entering the language, and existing words are finding new meanings. Space constraints limit the dictionarys actual value.And the points in favor of electronic dictionaries are even more compelling than the case against printed ones. Hyperlinks allow for quick learning about related items. Audio pronunciations beat out transcriptions in obscure formats. Photos and even videos are a snap to include. Blogs and other meta-content enrich the experience. Electronic data storage has already revolutionised lexicography. Huge searchable corpora of text allow dictionary-makers to find ea rlier and rarer words and usages than ever before. To have vast, rich and growing data going into the dictionary, and a bound and static product coming out, seems absurd. The Lighter Side of Dictionaries Dave BerryIf you have a big enough dictionary, just about everything is a word.Ogden NashSeated one day at the dictionary I was pretty weary and also pretty ill at ease,Because a word I had always liked turned out not to be a word at all, and suddenly I found myself among the vs.And suddenly among the vs I came across a new word which was a word called velleity,So the new word I found was better than the old word I lost, for which I thank my tutelary deity . . ..

Essay On Shakespeare s Beowulf And Anglo Saxon Society

Role of Women in Beowulf and Anglo-Saxon Society Beowulf, the hero of Anglo-Saxon epic, had many adventures, and many companions and fellow-warriors are mentioned throughout his story. Some of them seem noble and courageous, truly living up to the standards of their culture; some seem cowardly. But all have gained immortality in the words, many times transcribed and translated, of the famous epic. However, the women of the time are rarely mentioned in Beowulf. Still, even from those few women who are mentioned and from other documents of the era, it is possible to see the position of women in of Anglo-Saxon society. In many cases, they enjoyed more rights than women in later Medieval cultures. Both Wealhtheow, Hrothgar s queen,†¦show more content†¦Another indication of the power wielded by queens is the respect accorded to Hygd. She is beautiful, wise and young. Beowulf gives her the necklace that Wealhtheow had given him as well as three horses. That may have been a gesture meant to win her support within the court. Page states that the queen or noble lady of real life must often have acted a diplomatic part like this [Wealhtheow s requests], and have been a force to reckon with, and that the diplomatic marriage , linking nations or great families, was common...and the daughter of a royal house must often have been used to heal enmity between peoples or to cement friendship. However, those diplomatic marriages were not always successful. Freawaru s marriage fails to heal the enmity between the Danes and the Heathobards, as does the marriage of the princess Hildburh, whose tale is told by the scop at Hrothgar s banquet. Still, at least by the eleventh century, the bride had to agree to the marriage for it to be lawful (Gies 106). Most likely, that provision was in effect earlier, even if it was not spelled out in law. Further legal rights of Anglo-Saxon women included the right to own property. (Beowulf gives the necklace and horses to Hygd, specifically, and other gifts to Hygelac.) They could inherit property from husbands, brothers, sisters, children parents and other relations.

Security Issues in Software Defined Networks - MyAssignmenthelp

Question: Discuss about theSecurity Issues in Software Defined Networks. Answer: Introduction The rise of SDN has started critical enthusiasm for re-examining the established ways to deal with system engineering as well as design. The SDN is an idea, which is totally to break the customary networks or systems where the switches chooses the activities to do. The Software Defined Networking makes it conceivable to deal with an in-place network in the software, by composing programs that change the network exercises to run well with particular applications and conditions. The SDN software engineers manage a few intricacies identified with two-layered design, low level functions and occasion reordering . Security Issues or challenges in Software Defined Networks The integrity and security of SDN stay problematic, especially with the controller that is a solitary purpose of disappointment. The security should be everywhere within the SDN. As indicated by Bindra, the SDN security should be incorporated with the engineering, and additionally be conveyed to the administration to ensure the accessibility, honesty, and protection of every single associated asset along with the information (Bindra, Sood, 2016). Beyond the design itself, how the safety of SDN ought to be sent, overseen, and controlled in the SDN situation is still particularly up for snatches. There are contending approaches that some trust security is appropriately installed in the system, while others believe that it is appropriately implanted in servers, stockpiling and other registering gadgets. In any case, the arrangements are intended to make a situation that is more adaptable, effective, and secure (Benzekki, El Fergougui, Elbelrhiti Elalaoui, 2016). Another class is devel oping for the safety security inside the cutting bound conditions called SDSec, which conveys to organize the security authorization by isolating the safety control level from the safety preparing as well as sending planes, like the manner SDN concrete the network control level from the causing level. The outcome is a dynamic appropriated framework that virtualizes the system security requirement work, scales similar to virtual machines as well as overseen like a solitary, coherent system. The safety or security challenges for SDN vary in a few regards from those of the traditional networks because of the particular system execution as well as SDN's inalienable control as well as programmability attributes. For example, the idea of consistently brought together control may uncover a progression of high-esteem advantages for attackers or hackers while the capability to straightforwardly get the access to the control plane outcomes in another assault surface. And for SDN, numerous vul nerability investigations have been executed and a few of these attentions are implemented on OpenFlow convention (Channegowda, Nejabati, Simeonidou, 2013). According to Duan, the Software Defined Networking group is extremely mindful of the issue (Duan, Ansari, Toy, 2016). The Open Networking Center, steward, has distributed a paper in the 2016 that distinguished the two possible SDN security challenges or issues, or roads of conceivable attackers that the organization must address. The focused controller is the "Expected single intention of assault as well as the failure of the network. The Southbound user interface, for instance, OpenFlow among the information-sending gadgets and controller are helpless against the dangers that could debase the accessibility, execution and honesty of the whole network (Cui, Yu, Yan, 2016). As indicated by Khondoker, the first thing which comes from customers about the SDN is that they see security challenges in the SDN as an inhibitor to the SDN (Dayal, Maity, Srivastava, Khondoker, 2016). The Software Defined Networking controller is the prime focus for programmers since it is both, an essential i ssue of consequence in the network as well as the potential main issue for the failure of the network. I believe that my posts have completely contributed to help the readers to get knowledge about the challenges of the SDN as well as I also find the summary presented by all the selected peer reviews accurate. Based on the unique SDN security challenges, this document add the SDN security principles, safety requirements for the ONF protocols, as well as the security analysis of the Software Defined Networking. There are large number of chances for the aggressor to roll out the amend to the whole supporting of the network activity conduct just by altering the controller (Farshin, Sharifian, 2017). Indeed, even conventional network administration instruments do not give the ability to progressively change the whole conduct of the network on the hub to hub basis. The Program-ability of the Software Defined Networking controllers demonstrate a twofold edged sword. The designers introduce safety applications on a entire controller's northbound user interface to create amended approaches to utilize security strategies on the network. Those concerns train the SDN controller to apply the switches and switches that it manage as a strategy execution focuses. Nonetheless, that programmable northward interface is in addition a potential imperfection. Those applications might reconstruct the system through the controller. Programmers can trap the engineers to introduce bargained applications. With adequate learning about the cordial applications moving on the SDN controller, the programmer could make the system accomplish something totally unforeseen by the system supervisor just by delivering a precisely created bundle flow to the network (LIN, WANG, 2016). One important issue that is not addressed properly in this discussion is that the assailants can focus on a network component from inside the whole network itself. An aggressor could hypothetically increase the unapproved physical and virtual access to the user network and trade off a host which is as of now associated with the SDN and afterwards attempt to perform the assaults to destabilize the components of the network. This could be a kind of DoS assault or it could be a sort of fluffing assault for attempting to assault the network elements. The Centralized Control is the other issue which is not adequately mentioned in the peers. The Centralized control or coherently brought together control has uncovered a high-esteem advantage for assailants (Muciaccia, Passaro, 2017). The assailants may endeavor to control the elementary network performance and even control or manage the whole network by deceiving or trading off a SDN controller. This is particularly from a bigger number of self-sufficient resources in a totally dispersed control domain. On the other hand, the Provability is the other issue which is also one of the biggest challenges in the SDN. This new plan of action presents the prerequisites that don't exist in the shut managerial spaces as far as securing framework honesty, outsider information and open interfaces. An aggressor could likewise use these conventions and endeavor to instantiate new streams into the gadget's stream table (Sha, He, Fu, Sun, Li, 2015). This challenge is essential, because as SDN develops, it guarantees its clear nimbleness. The correspondence specialist co-ops alike possess the capacity to essentially quicken an opportunity to convey the new applications and administration as an immediate consequence of programming characterized innovation. From a framework observing point of view, it likewise makes the connection of execution occasions, simpler and pleasing the fast on-request growth. The inescapable uptick popular f or the new procedure, network and capacity in programming characterized framework represents a hazard for checking the stages. These arrangements must have the capacity to add observing ability to suit the fast development of the framework. In case that they can't include extra limit requests, they can rapidly end up noticeably over-subscribed, making the execution imperturbability gaps. Unlike the heritage foundation in the SDN world, the users can have a different overlay topology running on top of the sensual network. According to Smelyansky, the SDN challenges put several impacts on the real life (Smelyansky, 2017). For example, in case if some employees in an organization are not focusing, it really turns into the phenomenally very high-benefit centering point for the hacker, who might be very easily trade off, change some of the users code base as well as re-script the control of the activity such that the employees ex-filtrating the information as well as reserving the information at some place where an aggressor can completely sniff it," said Smelyansky, the security expert of Voodoo and a leading employee at IANS (Smelyansky, 2017). The controller is the basic assault target as well as in this manner, it must be fully solidified. Solidifying safety standards of the entire controller along with system the system constituent normally comes down so that they host the OS solidifying. Each and every prescribed activity for solidifying the OCL servers are suitable here. Still, many associations wi ll demand to nearly control or monitor controllers in the organization for any type of suspicious activities. The associations similarly need to avert the disapproved access to the Software Defined Networking control networks (Yan, Zhang, Vasilakos, 2015). The Software Defined Networking framework ought to take into account the design of secure and validated head access to the controller. Reflection and Conclusion After this study, I have gained a lot of knowledge about the SDN challenges. It has been reflected in this study that over the recent years, the Software Defined Networking has created from only a thought to a worldview that the expansive networks administration sellers are grasping as well as taking their models for the future venture arrange administration. This innovation includes more noteworthy granularity, elements and the ability to reason the networking administration, yet raising different worries that ought to be seen from a safety point of view. With the creative new innovation comes the security worries that could without much of a stretch could go ignored. How about we investigate a couple of security-related issues to know about while executing the Software Defined Networking. The larger part of the programming characterizes and organizes the security concerns advance around the controller itself. The controller can be viewed as the brains of the exchanging or steering, which permits the control board from every framework to be halfway overseen. In any case, by giving the Software Defined Networking controller brought together an administration over system hubs to push down changes to these frameworks, it winds up noticeably basic that the security around this framework is secured.

Levendary Cafe the China Challenge free essay sample

Levendary main issue is not entering Chains market but whether such decision is a right decision and if do so how to survive in such aggressively competitive market, to which extent the management have a detailed plan about and control over the penetration in the new market, adequate information about the culture and a proper communication with the management in china. When Levendary entered China they gave Chen the full control over the operations there, although a well-developed detailed plan and a clear tactic of how to implement this plan is a must. However it is clearly this is not the case whereas everything had been handed to Chen from A to Z. The chain of Levendary Cafe in USA are run by a strict set of rules and allowing modifications only after approval from the concept group regarding the â€Å"look and feel† of the firm. The Levendary Cafe in China is following a business model which is completely different from that of the US operation model. We will write a custom essay sample on Levendary Cafe : the China Challenge or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Chen wanted this cafe to adapt to the changing tastes of people from place to place. However he has no clear strategy or reasonable clarification for some actions such as locating some cafes in suburbs or in rural areas although there is so much room for expansion in the huge urban markets or turning some cafes into counter-only. And this might be because the philosophy and operations of Levendary have not been communicated clearly to Chen from the beginning and there was no control for 18 months that Chen worked during without referring to the US management. The culture differences between US and China is another major issue that should be understood by Headquarter in US. Customers in China are different from those in US in term of their habits and food preferences. Chen was smart by being flexible when entered Chinese market because there are some features that could not be transferred easily into such closed community nevertheless killed the identity of Levendary and turned it to a completely different restaurant while trying to adopt to the new culture. He could have been using the differences as a competitive advantage and differentiate the restaurant among other rivals. For example, serving organic fresh food which is strength of Levendary would be valued by Chinese consumers who look for fresh food and have concerns about it or the personalized services that Levendary is well-known for and Chinese restaurants lack for. Another issue is the lack of experience with the international market. Levendary headquarter should be aware of the international operations and the problem associated with and how to fit in and gain a strong position in such market. They should have more control over the financial reports to follow one reporting style that is consist with the accepted principles. Chen has no excuse for not following the GAAP in the financial reports he submitted which should be taken into consideration and corrected immediately. Question 2: What changes (if any) should Mia Foster make? Specifically, what should she do about Louis Chen? And what changes (if any) would you propose at headquarters? The changes should be made to the operation In China, the relationship with Chen and to the headquarters. Levendary cafe in china should not be completely different from that of US yet the flexibility is a must to survive in China. Foster should cooperate with Chen to find the proper way to adopt the Chinese culture and style in term of the menu choices yet they have to capitalize on what they are good in and use it as a competitive advantage such as the personalized services and the fresh organic food. They need to be differentiated to be considered by the Chinese customers. The stores should be located according to a strategic plan rather than opportunistic ones. Urban arias are the best choice for Levendary. Finally, a plane for the operation should be put and controlled. Regarding the relationship with Chen, a meeting with Chen, Foster and the concept team must be held. Foster who is a good communicator should make everything clear to Chen and let him know to which extent his changes are acceptable and to emphasize on the identity of Levendary and the image that they want consumers to have. Another important issue is that Chen has to conform to the companys planning and reporting processes and work in light of the corporate strategy. Foster should discard the option of firing him since he has many qualities like the Chinese language, the connections in China and also he is willing and eager to make this work and also, it is hard to find a replacement. Since she is known for her frank communication style, she should use that with him and give Chen notice that his opportunity for contract renewal may be in jeopardy if Chen cannot work together with Foster and her management team to resolve all the problems The headquarters should cooperate more with Chen and closely monitor the operation in China by having periodic reports to correct any deviation from the plan. They have to give the needed support to have the financial reports in accordance with GAAP and to give the training if needed for the staff in China. Question 3: Prepare a specific action program for Foster to her deal with the need for continued growth in China. What should be on the agenda for her meeting with Chen? What should be on the agenda is: 1. The marketing strategy: Foster should discuss a plan to deliver a clear, consistent, and compelling message about Levendary cafe and create both physical and perceptual differences that can be perceived by consumer in China that is consistent with the corporate strategy of the mother company. Chen should be part of this to have commitment and responsibility to it and due to his experience in the Chinese market. 2. The financial reports style: Foster should force Levendary China to follow the mother companys reporting style and show that any deviation is not acceptable. Chinas finance team Chen are responsible for that and headquarters are responsible for providing any needed support or training. 3. The cost and revenue: : a specialized team should invistigate why the composition of expenses of China operations is quite different than U. S. operations and find way to cut costs and increase revenue. Chen has to have a plan of how to reach the break-even point within 9 months (by the end of Chens Contract). 4. Control over Chinas operations: Foster should schedule for periodic audit and visit for Levendary China and define the responsibility of Chen and the extent to which he must not take decision without getting the approval from US. Because it seems that the proper communication is missing. Question 4: What global issues are addressed in the case? Identify them and discuss them in depth Some of the global issues highlighted by the case are the culture differences, the communication with the subsidiary and the financial considerations. Culture Differences: There are difference between the Chinese culture and the American culture. Some differences include the fact that in China people go to eat at a restaurant and quickly leave they don’t sit around whereas in the States going to a restaurant is a socializing experience. This is the reason the development in China of the cafe’s is structured differently to those in the USA. The preferred food is different too such as he cheese that is not liked by Chinese. There seems to be a missing link between the two cultures that is not being understood by headquarters who must adapt to Chinese culture in order to survive and find the fine line between introducing the American tastes and values to the Chinese market and responding to the local taste. Communication: The second aspect is the barriers that exist with communication. Headquarters did not do anything to support the business structure in China. Chen feels that they are not recognizing his effort when Foster talked to him about her concern. Lack of proper communication led to such situation where Chen did everything without referring to US Levendary which is considered by Foster as dramatic departures from Levendary’s U. S. concept. A clear communication rules would prevent such problems. Financial consideration: The subsidiary company should not have a different reporting style from the mother company. Having a uniform style is must. It s important that Foster and the home-based Finance Department take a hard look at the numbers from the Chinese operations and investigate the unreasonable cost figures. It is important to have a experience of the Chinese market which is considered one of the cheapest for the paper for example but the financial statement of Levendary China shows a dramatic number as well as for the occupancy cost. Question 5: What are Louis Chen’s qualities as a global leader? Discuss them in li ght of China and the US. †¢He had MBA from Stanford University. He is Bilingual in English and Mandarin Chinese. He was familiar with the neighborhoods in Shanghai and Beijing since he had long experience as a retail property developer, so he knew the impact of store location on profitability. He had strong connections with many real estate agents in China which helped him to locate in prime sites at fair price. He had entrepreneurial spirit to work in the restaurant industry with no experience in this sector, and he was confident that Levendary will success in the Chinese market. His go-getter (an aggressively enterprising person) that developed to become a local baron which might be a professional manager if trained well.

Ancient China - Periods and Dynasties

Ancient China - Periods and Dynasties Chinese recorded history goes back more than 3000 years and if you add archaeological evidence (including Chinese pottery), another millennium and a half, to roughly 2500 B.C. The center of Chinese government moved repeatedly throughout this period, as China absorbed more of eastern Asia. This article looks at the conventional divisions of the history of China into eras and dynasties, starting with the earliest about which we have any information and continuing through to Communist China. Events of the past, if not forgotten, are teachings about the future. - Sima Qian, Chinese historian of the late second century B.C. The focus here is on the period of ancient Chinese history that begins with the advent of writing (as also for the Ancient Near East, Mesoamerica, and the Indus Valley) and ends with the period that corresponds best with a conventional date for the end of antiquity. Unfortunately, this date makes sense only in Europe: A.D. 476. That year is in the middle of the relevant Chinese period, the Southern Song and Northern Wei Dynasties, and is of no special significance for Chinese history. Neolithic First, according to historian Sima Qian, who chose to begin his Shiji (Records of the Historian) with the Yellow Emperor tale, Huang Di unified tribes along the Yellow River valley nearly 5,000 years ago. For these achievements, he is considered the founder of the Chinese nation and culture. Ever since 200BC, Chinese rulers, imperial and otherwise, have considered it politically convenient to sponsor an annual memorial ceremony in his honor. [URL www.taipeitimes.com/News/editorials/archives/2006/05/04/2003306109] Taipei Times - Dumping the Yellow Emperor Myth The Neolithic (neonew lithicstone) Period of Ancient China lasted from about 12,000 until about 2000 B.C. Hunting, gathering, and agriculture were practiced during this period. Silk was also produced from mulberry leaf-fed silkworms. The pottery forms of the Neolithic period were painted and black, representing the two cultural groups, Yangshao (in the mountains of the north and west of China) and Lungshan (in the plains in eastern China), as well as utilitarian forms for daily use. Xia It had been thought that the Xia were a myth, but radiocarbon evidence for this Bronze Age people suggests that the period ran from 2100 to 1800 B.C. Bronze vessels found at Erlitou along the Yellow River, in northern central China, also attest to the reality of the Xia. The agrarian Xia were ancestors of the Shang. More on the Xia Reference: [URL www.nga.gov/exhibitions/chbro_bron.shtm] The Golden Age of Classical Archaeology Beginning of the Historical Era: Shang The truth about the Shang (c. 1700-1027 B.C.), who, like the Xia, had been considered mythical, came as a result of the discovery of the writing on oracle bones. It is traditionally believed that there were 30 kings and 7 capitals of the Shang. The ruler lived at the center of his capital. The Shang had bronze weapons and vessels, as well as earthenware. The Shang are credited with inventing Chinese writing because there are written records, notably the oracle bones. More on the Shang Dynasty Zhou The Zhou were originally semi-nomadic and had co-existed with the Shang. The dynasty began with Kings Wen (Ji Chang) and Zhou Wuwang (Ji Fa) who were considered ideal rulers, patrons of the arts, and descendants of the Yellow Emperor. The great philosophers flourished in the Zhou period. They banned human sacrifice. The Zhou developed a feudal-like system of allegiance and government that lasted as long as any other dynasty in the world, from about 1040-221 B.C. It was adaptable enough that it survived when barbarian invaders forced the Zhou to move their capital to the East. The Zhou period is sub-divided into: Western Zhou 1027-771 B.C.Eastern Zhou 770-221 B.C.770-476 B.C. Spring and Autumn period475-221 B.C. Warring States period During this period, iron tools were developed and population exploded. During the Warring States Period, only the Qin defeated their enemies. More on the Zhou Dynasty Qin The Qin Dynasty, which lasted from 221-206 B.C., was begun by the architect of the Great Wall of China, the first emperor, Qin Shihuangdi (aka Shi Huangdi or Shih Huang-ti) (r. 246/221 [start of the empire] -210 B.C.). The wall was built to repel nomadic invaders, the Xiongnu. Highways were also built. When he died, the emperor was buried in an enormous tomb with a terra cotta army for protection (alternatively, servants). During this period the feudal system was replaced by a strong central bureaucracy. The second emperor of the Qin was Qin Ershi Huangdi (Ying Huhai) who ruled from 209-207 B.C. The third emperor was the King of Qin (Ying Ziying) who ruled in 207 B.C. More on the Qin Dynasty Han The Han Dynasty, which was founded by Liu Bang (Han Gaozu), lasted for four centuries (206 B.C.- A.D. 8, 25-220). During this period, Confucianism became state doctrine. China had contact with the west via the Silk Road during this period. Under Emperor Han Wudi, the empire expanded into Asia. The dynasty is to divided into a Western Han and an Eastern Han because there was a split following the unsuccessful attempt by Wang Mang to reform the government. At the end of the Eastern Han, the empire was divided into three kingdoms by powerful warlords. More on the Han Dynasty Political disunity followed the collapse of the Han Dynasty. This was when the Chinese developed gunpowder for fireworks. Next: Three Kingdoms and Chin (Jin) Dynasty Source of Quote Archaeology and Chinese Historiography, by K. C. Chang.

The period from 220 to 589 is often called the period of 6 dynasties, which covers the Three Kingdoms, Chin Dynasty, and Southern and Northern Dynasties. At the start, the three leading economic centers of the Han Dynasty (the Three  kingdoms) tried to unify the land: The Cao-Wei Empire (220-265) from northern ChinaThe Shu-Han Empire (221-263) from the west, andThe Wu Empire (222-280) from the east, the most powerful of the three, based on a system of confederation of powerful families, which conquered the Shu in A.D. 263. During the period of the three kingdoms, tea was discovered, Buddhism spread, Buddhist pagodas were built, and porcelain was created. Chin Dynasty Also known as the  Jin Dynasty  (A.D. 265-420), the dynasty was started by Ssu-ma Yen (Sima Yan), who ruled as Emperor Wu Ti from A.D. 265-289. He reunified China in 280 by conquering the Wu kingdom. After reuniting, he ordered the disbanding of the armies, but this order was not uniformly obeyed. The Huns eventually defeated the  Chin,  but were never very strong. The Chin fled their capital, in Luoyang, ruling from 317-420, in  Jiankan  (modern Nanking), as the Eastern Chin (Dongjin). The earlier Chin period (265-316) is known as the Western Chin (Xijin). The culture of the Eastern Chin, remote from the Yellow River plains, developed a different culture from that of northern China. The Eastern Chin  were  the first of the Southern dynasties. Northern and Southern Dynasties Another period of disunity, the period of the Northern and Southern dynasties lasted from 317-589. The Northern Dynasties were The Northern Wei (386-533)The Eastern Wei (534-540)The Western Wei (535-557)The Northern Qi (550-577)The Northern Zhou (557-588) The Southern Dynasties were The Song (420-478)The Qi (479-501)The Liang (502-556)The Chen (557-588) The remaining dynasties are clearly medieval or modern and so are beyond the scope of this site: Classical Imperial ChinaSui 580-618 A.D. This short dynasty had two emperors Yang Chien (Emperor Wen Ti), an official of the northern Zhou, and his son Emperor Yang. They built canals and fortified the Great Wall on the northern frontier and began expensive military campaigns.Tang 618-907 A.D. The Tang composed a penal code and started a land distribution project to help the peasants, and expanded the empire into Iran, Manchuria, and Korea.

Revising with the Present Perfect

Revising with the Present Perfect Revising with the Present Perfect Revising with the Present Perfect By Maeve Maddox The following item appeared in the column of one-sentence news items on the front page of my morning newspaper: William Bradford Bishop Jr., who was a State Department employee in 1976 when he is suspected of killing his wife, mother and three sons, was added to the FBI’s list of â€Å"Ten Most Wanted Fugitives,† drawing renewed attention to the case. Conveying a coherent report in 50 words or less is quite a feat, and the writers in my paper usually do an amazingly good job of it. Nevertheless, this strange assortment of verb tenses left my grammar nerve twitching. The principal fact being reported is that the FBI has added Bishop to the list of â€Å"Most Wanted Fugitives.† Next in importance is the reason for which Bishop was added to the list: he is a suspected murderer. Last in importance is the fact of Bishop’s employment at the time of the murders. All three facts refer to past events, so present tense is definitely does not belong. Changing the is to was would help, but then we would have: â€Å"Bishop, who was an employee in 1976 when he was suspected, was added to the list.† Not only does this revision produce a litany of three wases in a row, it obscures the most recent event being reported: the fact that the man has been added to the â€Å"Most Wanted Fugitives† list. What we need is a tense that will distinguish the most recent past from the remoter past. Enter the present perfect: William Bradford Bishop Jr., suspected of killing his wife, mother and three sons in 1976 when he was a State Department employee, has been added to the FBI’s list of â€Å"Ten Most Wanted Fugitives,† drawing renewed attention to the case. Both was added (simple past) and has been added (present perfect) describe completed actions, but the present perfect describes a completed action that is still relevant in the present. The present tense auxiliary has adds an immediacy to the news item that alerts the reader to which of the three facts being reported is the most recent.

Movie Essay Example | Topics and Well Written Essays - 500 words - 4

Movie - Essay Example However, it is clear that gender is the main theme since hitch shows gender roles that women and men fulfill in the society, which are highly stereotypical. Thus, watching this movie can help people relate to the characters featured in it; hence, impacting their lives. Therefore, this paper will show how the media, through the Hitch movie, enables people to connect with the characters in the movie; hence, impacting their lives in a significant way. At first, Hitch teaches men how to approach women by explaining the dos and don’ts of dating, and what women prefer in relationships. However, he later realizes that it is not possible to study women since they are all different; thus, there are no basic principles required in looking for women. Similarly, when searching for women, many men start by making a perfect plan on how to get a girl, and then later realize that they cannot make one since people are different. For this reason, I believe that the movie producers incorporated this scenario in order to connect with many people since this is a common situation among many people in the society; thus, making an impact in their lives. Also, the movie shows the common gender norms such as the stereotype that men are over confident, as well as initiators in relationships. Hitch teaches men how to approach women because he believes that men should initiate relationships and act confident when approaching women, as well. For instance, while, in a club with his friend, Hitch noticed that his friend kept on staring at a certain gal in the club. He then said to his friend â€Å"I’m going to get those women over here† (Guinones, 2010). This portrays confidence in Hitch’s character by choosing to make the first move to get the women. Also, it shows that men should be brave enough to initiate a connection with women. Thus, it is easy for men watching the movie relate to Hitch’s character, and may be inspired to act the same way. In summary, according

AUDITOR INDEPENDENCE AND AUDITOR SCEPTICISM Essay

AUDITOR INDEPENDENCE AND AUDITOR SCEPTICISM - Essay Example To justify these responsibilities an auditor must possess certain personal qualities such as honesty and ethicality. To be precise, the auditor whether internal or external, has his responsibilities towards the governance of an organisation and its quality (The Institute of Internal Auditors, 2005). However, in the realistic phenomenon auditors have been constantly judged on their personal qualities, which directly indicate to the appropriateness of the concept of auditor independence and scepticism. The concept of auditor independence and scepticism were both raised with the focus on the nature of responsibilities which a professional needs to abide while ensuring the quality of the financial statements of a company (Kleinman & Et. Al., 2001). Nature of Auditor Independence and Auditor Scepticism The Nature of the Auditor Independence To define the term ‘Auditor Independence’, authors have referred it as the foundation of auditing in a realistic behaviour. Relying on th e nature of auditing, auditors need to identify, control and eradicate the inefficiency of the financial statements produced by the accountants of a firm in order to ensure the accurate status of the financial health of the organisation. Auditor independence, in this scenario assists the auditor to render value-added services to the client and the community at large. Auditor independence is strongly influenced by the audit process. The process instigates from the selection procedure and ends by reporting the findings and opinion of the auditor. Therefore, the concept of audit independence emerges to be crucial with due consideration to its importance and nature. It is in this context, that audit independence is implemented based on three basic principles, i.e. the auditors must belong to the external environment of the organisation and therefore are prohibited to be a part of the client organisation, the auditors are also proscribed to audit their own workings and cannot play any ad vocacy role to support the organisation if found guilty (Rezaee, 2007). Nature of Auditor Scepticism Auditor Scepticism is another concept introduced in the auditing practices, which refers to the personal skill of the auditors to challenge the management’s statements in order to critically evaluate the accuracy of the financial statements of an organisation. However, scepticism needs to be controlled due to the fact that challenging almost any and every assertion of a well established company will in turn affect the willingness to publish the financial statements (Peursem, 1989). The factors which play a crucial role in determining the appropriateness of scepticism are the regulations prescribed in relation to auditing and the financial practise of the company and the nature of the corporate. To be precise, the nature of auditor scepticism indicates to be an attitude of questioning the management and identifying and eliminating the probable chances of producing misstatements related to error or deception. It is of vital importance due to the fact that it not only ensures the auditing to be confirmed with extra professional efficacy but also proves supportive in performing the task rigorously. However, the level of

Evidence based practice Essay Example for Free

Evidence based practice Essay American Academy of Pediatrics and the American Academy of Family Physicians. [Clinical practice guideline:]. (2004). Source Of EvidenceThis evidence meets the criteria for a filtered source. It was sourced online from the Official Journal of the American Academy of Pediatrics and Family Physicians. Specialists from multi medical disciplines assembled to create an integrative systematic study and review of the current evidence- based literature available for the treatment and management of Acute Otitis Media (AOM). The conclusions and findings were utilized to devise guidelines and a practice protocol that recommended early diagnosis and makes recommendations for the management of AOM in children aged between 2 months and 12 years old. Quantitative data such as randomized, controlled trials and comparative cohort studies were to ensure quality of the evidence. The guideline was reviewed by a number of professional peer groups prior to introduction and publication. Appropriate For Nursing Practice The evidence in the article is applicable and appropriate for nursing practice. The guideline clearly defined the care and best practice treatment options for children with AOM and also the situations when the guideline is not appropriate, like children with a reoccurrence with in 30 days. The recommendations act as a template to guide clinician’s treatment options using evidence based standardized protocol, which can be shared with anxious patients to give validity to help understand their child’s diagnosis and treatment. Source of Evidence Classification This articles source is classified as evidence-based guidelines and research. Specialist and peer recognized experts jointly convened and defined the subject for the study and developed a theoretical framework to review the literature and developed a guideline for standardizing the diagnosis, treatment and management of pediatric AOM using research based knowledge. Block, S. L. (1997). Causative pathogens, antibiotic resistance and therapeutic considerations in acute otitis media Source Of EvidenceThe source of this article is classified as unfiltered and was retrieved from a medical database -PubMed. The article published in The Pediatric Infectious disease Journal offers a synopsis of the research of the author on  identifying the common the bacterial pathogens isolated as the causative agents in children presenting with AOM. The author also discussed traditional treatment with antibiotics and the problem of microbial resistance and the availability of newer antibiotics as treatment options. Appropriate For Nursing PracticeThe evidence in this article is a ppropriate for nursing practice, as it raises awareness of increased incidence of microbial resistance to the traditional first line management and treatment of children with AOM and offers treatment options with newer more effective antibiotics. Source of Evidence ClassificationThis article is classified as a research evidence summary. The author collected quantitative data related to the incidence of the pathogens that most commonly caused AOM infectious in children and the microbe demonstrating increasing resistance. The article made recommendations for treatment of AOM based on the findings and made recommendations such as increase antibiotic doing for certain bacterial strains of AOM. Kelley, P. E. , Friedman, N. , Johnson, C. (2007). Ear, nose, and throat. In W. W. Hay, M. J.Levin, J. M. Sondheimer, R. R. Deterding, Current pediatric diagnosis and treatment. Source Of EvidenceThis source is classified as general information. It was sourced from the Ear Nose and Throat chapter of the textbook â€Å"Current Pediatric Diagnosis and Treatment†, which discusses the general presentation, signs, symptoms and course of AOM infections. It also details the management, treatment and prognosis. Appropriate For Nursing Prac ticeThis source has relevance to nursing practice as it clearly gives an overview of AOM in pediatric setting. Although given in medical model format, nurses need to have knowledge of the pathogens, symptomology, treatment and course of the infection to be able to formulate nursing care plans and actions. They need to have an awareness of the most current treatments to be able to advocate for their patients. Source of Evidence ClassificationThe source of this evidence is classified as â€Å"none of these. There is no primary research, literature review, experimental studies or clinical trials. The authors are experts in the field of Ear Nose and Throat specialty and provided an accepted general overview of the care and management of AOM as appropriate in 2007. McCracken, G. H. (1998). Treatment of Acute Otitis Media in an Era of Increasing Microbial Resistance. Source Of Evidence This article can be classified as an unfiltered source. The article was sourced from the medical database, PubMed and published in Pediatric Infectious Disease Journal, a professional peer reviewed journal. The researcher conducts a search of the data base and screens and evaluates primary research related to the topic. The article discussed the common pathogens that cause AOM and distinguished between simple and complicated presentations and made recommendations for differential diagnosis and antibiotic treatment options. Appropriate For Nursing PracticeThis article is appropriate to nursing practice, as provides a very good overview AOM in particular related to the history and incidence of the problem and the difficulty for providers in diagnosis and the pressure to prescribe antibiotics. Treatment recommendations are made and rationales for when antibiotics is not the first line of treatment in view of rising rates of microbial resistance Source of Evidence ClassificationThis source of evidence is classified as an evidence summary, the author reviews the research on AOM pre 1997 and evaluates the data to make a recommendations and provides a guideline for AOM treatment and diagnosis. The author cites multiple sources and references. Parent Interviews: Source Of EvidenceThis source of evidence is unfiltered, general information gathered from parents with children with AOM. It is retrospective, anecdotal accounts of signs, symptoms and course of the illness that they observed and related to the nurses. It can’t be quantified or validated but is useful to gain insight into the experience and perceptions of parents coping with a sick child Appropriate For Nursing PracticeThis data while appropriate information for nurses to gather, does not meet the criteria for research. There is no framework or theoretical model that was designed and followed and no uniformity of information collected. Interviewing the parents can give some insight into activity of the child and the onset of the symptomology that could lead to observing some commonalities and then research could be instituted. Interviews are also appropriate clinically as parents can offer insight in to coping or lack of coping skills with their sick child and can lead to parent education on care of the child with AOM. Source of Evidence ClassificationThe source of this evidence is classified as â€Å"none of these. Parental interviews can’t be classified as evidence and is not a legitimate source; It does not meet the criteria to be called evidence or research. The parents’ responses are personal and anecdotal and are not objective and the interviews were conducted informally with no structure framework for data collection. B1. Watchful Waiting: Acute Otitis Media, (AOM) an ear infection commonly diagnosed in children and by age three, 50% to 70% of children will have had at least one incidence of the infection. In the year 2000 sixteen million visits to doctor’s office with thirteen million prescriptions at indirect cost of $1. 02 billion were attributed to AOM. (Diagnosis and management of acute otitis media, 2004) The rise in resistant strains of bacteria has made the medical and nursing profession search for answers on the appropriate use and dispensing of antibiotics. For many years family practitioners and pediatricians have spoken about parental pressure to prescribe antibiotics for self-limiting viral illnesses. Many doctors, who refused, could be frustrated by colleagues who bowed to the pressure to prescribe. (Marcy, 1999) It was recognized that there was a need for research and guidelines to develop a standardized approach. Evidence was needed to formulate what was best practice that would deliver rational evidence based care in a cost effective reasonable manner. In response to these concerns, the American Academy of Pediatrics and the American Academy of Family Physicians convened a panel of experts to review the research and data available and to analyze and summarize the facts and statistics to create a guideline for the management, diagnosis and treatment of AOM in children from 2 months to 12 years. The data collected indicated that an observation protocol was needed if the use of unnecessary antibiotic therapy was to be curbed. Results from controlled clinical trials that were done with placebo control groups validated the data collected over a 30 year time span. They found that in 75% of cases, the condition resolved without prescribing antibiotics, within seven days. They also recognized in certain incidents that observation and symptomatic management of fever and pain was not appropriate and treatment should be immediate, and an exclusion criterion was included in the guideline. These included children who represented with AOM that was obviously severe and there were certain clinical signs that lead to a certainty or severity of the diagnosis or if there was a reoccurrence within 30 days of initial consultation. The guideline was not designed to supplant the clinical judgment of the practitioner but to support it and provide validated evidence to corroborate the observation protocol, AKA ‘Watchful Waiting’ It gives practitioners rational for treating uncomplicated AOM and preventing the masking of other symptoms more serious conditions by unnecessary antibiotics. In addition doctors have validated information to share with parents to reassure them that the illness will resolve without antibiotics and educate them on symptomatic management of their children symptoms. C. Application of Findings: There are many reasons why healthcare organizations are motivated to introduce new practices procedures or guidelines some of these reason include to achieve certification, like Magnet status or become compliant with health regulation. Sometimes changes are for cost savings are to improve market share of certain health consumers. Nurses look to research to improve patient care or the effectiveness of practice. Most hospitals and organizations use certain change management models like Six Sigma or DMAIC to introduce new policies, procedures and practices. Clinical practice councils or shared governance councils identify issues and staff has the opportunity to bring forward practices identified that could be improved. Some people find change difficult and are offer resistance and put up barriers. How a process or suggestion is framed and managed is vital to success if the change is to be achieved and sustained. In the case of a multidisciplinary group in a clinic, having research based evidence to support getting group support for the introduction of the guideline is fundamental. Getting physician buy in and agreement would be an important element. Barriers at clinic level have been recognized by other change adopters including â€Å"a lack agreement about the care process changes desired and little engagement of physicians† (Horscikoski, 2006). The efficacy and the credibility of the sources such as the of the research by American Academy of Pediatrics and the American Academy of Family Physicians lends standing to the proposal for adoption of the guideline. Once the nurse leadership had reviewed the research and the team approves the findings as best practice, the next step is to have the other disciplines review and approve and provide input in to translation of research guideline into a workable clinic protocol that has the support of all stakeholders. A plan, a time line and education are formulated prior to implementation of the guidelines and follow up and data is gathered post implementation to monitor success. D. Ethical Issues: Ethical considerations in healthcare research have been sensitive subject in the research community for many years. Unfortunately wise and ethical choices have not always been exercised. Few can be unaware of the case of the Tuskegee syphilis study (1932–1972), a study by the United States Public health Service, that knowingly did not treat a group of poor African American men for syphilis. When this was discovered it led to the founding of The Office for Human Research Protections (OHRP) under the provisions of the 1974, the National Research Act. (NRA) Its role is to deals with ethical oversight of human clinical trials and studies in conjunction with the National Institute of Health. (Wikipedia, 2014) Unfortunately even today ethical concerns continue to be of concern. Recently the OHRP found that â€Å"23 academic institutions authorized a research project that failed to meet the most basic ethical standards :†(NYT Editorial Board, 2013). The NRA mandated that research participants must give informed consent. They must be told of any risks and benefits. If there is a control group they need to know that they may not receive the investigational treatment. They must be aware that they have the right to leave the study at any time. Their privacy and health information must protected at all times. To meet NRA ethical requirements, the study should be to benefit patients and the knowledge should not be available by other means. Unnecessary mental or physical suffering is not permitted; it should do no harm, and be for a laudable purpose.D1. Ethical Issues in Vulnerable populations: Ethics in research is always of special concern but it is heightened when the target participants are unable to speak for themselves or give consent. In these vulnerable populations like the children, the mentally ill, the intellectually disabled or developmentally delayed the risk of abuse and the desire to protect is equally strong. Other grou ps that are considered vulnerable are the poor, the illiterate, non-English speakers and prisoners which sometimes are discounted as vulnerable. Special considerations are needed when these populations are the subject of research studies. As these populations can’t not give consent for themselves another entity or person consents on their behalf be it parent, guardian, institution or state. It raises moral questions about the motivation of those who have the power to consent for others to be in experimental trials and other forms of research. For this reason the Food and Drug Administration (FDA) and the Department of Health and Human Services (HHS) have developed special safeguards for children. The parents must give informed consent and the child must give age appropriate assent. Confidentially is another complicated issue, the Health Information and Portability and Accountability Act Privacy Rule instituted in 2003 states that records from research studies are confidential and release to subjects need be done if the conditions are justified. Parents have the right to receive information and reports on all their child’s records but often do not know about the 2003 laws provision. In addition, when a child reaches 12, State and Federal law limits parental access to certain medical information, which can cause conflict, discomfort and conflict of interest. Institutional review boards, to which research proposals must be submitted prior to the approval of any study, holds researchers to higher standards regarding the necessity and benefits of studies on the more vulnerable groups in society. They must ensure that risks to subjects are minimized and rational in relation to expected benefits and that the choice of participants is impartial.

Salem Power Plant :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  The Salem Harbor power plant is a serious threat to the public health – and it may only get worse. There is a severe concern about toxic air emissions from the prior waste disposal practices. That is why Bush’s energy plan doesn’t quite work? In the Salem Evening News it says that, â€Å"The Bush plan only pays lip service to the threat of global warming, the greatest environmental danger of our time.† (Kert Davies) The Bush plan may of solved the threat of global warming, but in reality Pollution from oil- and coal-burning power plants kills more people in Massachusetts every year than homicides and drunken driving combined. Why should the public be harmed every time they decide to take a jog around the block? People are dying each year due to the Salem Harbor power plant. â€Å"The activists planted crosses to symbolize the deaths caused by the mining and burning of coal made, making the point that the Bush plan is over reliant on coal, a dirty energy source.† (Davies) Not only does the Salem Harbor power plant kill people each year but other plants such as; â€Å"Brayton Point in Somerset; Canal Station in Sandwich; Mystic Station in Everett; Mt. Tom Station in Holyoke; and Somerset Station in Somerset† (Davies) kill people too. The real factor that kills the people is the coal. It may not seem it but â€Å"coal kills the people who mine it, and when corporate polluters burn it – coal destroys our air, and shortens lives.† (Davies) So should the general public be harmed everyday when they decide to go for a jog in the morning? What can be done to prevent coal from being used? There are enough new gas-fired power plants under construction to supply nearly half of New England’s peak demand. â€Å"Two new gas pipelines are now operational, adding enough natural gas supply to New England to power all the new plants currently being built.† (Davies) We don’t get our power from a particular power plant, but from the web of power plants and transmission lines across the region called the â€Å"grid.† â€Å"These new plants will come on line over the next one to two years, to compete against the old, dirty units to supply our electric power.† (Davies) So using the gas pipelines is one way to cut down on the coal. How about another way? In fact there

Philippine literature Essay

Philippine Literature is a diverse and rich group of works that has evolved side-by-side with the country’s history. Literature had started with fables and legends made by the ancient Filipinos long before the arrival of Spanish influence. The main themes of Philippine literature focus on the country’s pre-colonial cultural traditions and the socio-political histories of its colonial and contemporary traditions. It is not a secret that many Filipinos are unfamiliar with much of the country’s literary heritage, especially those that were written long before the Spaniards arrived in our country. This is due to the fact that the stories of ancient time were not written, but rather passed on from generation to generation through word of mouth. Only during 1521 did the early Filipinos became acquainted with literature due to the influence of the Spaniards on us. But the literature that the Filipinos became acquainted with are not Philippine-made, rather, they were wor ks of Spanish authors. So successful were the efforts of colonists to blot out the memory of the country’s largely oral past that present-day Filipino writers, artists and journalists are trying to correct this inequity by recognizing the country’s wealth of ethnic traditions and disseminating them in schools through mass media. The rise of nationalistic pride in the 1960s and 1970s also helped bring about this change of attitude among a new breed of Filipinos concerned about the â€Å"Filipino identity.† Philippine literature is written in Spanish, English, Tagalog, and/or other native Philippine Languages. Why do we need to study Philippine Literature? Whatever nationality you are it is always very important to study the literature of your country. In doing so you are not only learning about the historical aspects of your land, but you are also keeping alive the thoughts, beliefs and cultural variations of your ancestors that differentiate your country from the rest of the world. A country’s literature also tells us about its civilization in a form other than straight fact.

Child Soldiers essays

Child Soldiers essays What do you think of when you hear child soldiers? You probably think of them as trained children that were destined to be a soldier from birth that are trained and have the psyche to be soldiers. You probably think that the idea of children as soldiers is something in a science fiction book and that it does not have any basis on the real life. The reality is that child soldiers do exist and it is not what we think it would be. First off what exactly are child soldiers? They are actually just normal children and teenagers just like us (anyone under the age of 18 is legally considered a child). What makes them differ from us is that they were denied a childhood. Almost all areas that utilize child soldiers are areas that are in constant conflict (such as Iran and Iraq). Any person that is caught in an area of strife or battle can just be taken and turned into a soldier. The loyalties of these soldiers do not matter since the child is young enough that he/she is easily intimidated and thus easily controlled. The soldiers can be recruited from anywhere. They can be from the losers side of a fight or they can just be kidnapped off their homes. Some governments also draft children into their armies without any notice. Anyone that resisted is of course executed. Government soldiers came and forced me and my father to join them. My father refused so they cut his throat. They beat me and tied me and forced me to join the fighters.1 Sadly some fighters join the army on their own will for revenge or as protection. Most countries that have active child soldiers are the countries that experience chronic poverty; it is only natural that children join the army for food and shelter. The duties of these soldiers are almost the same. They serve as spies, scouts, messengers, and they, of course, fight on the front lines in a battle. Most children do menial tasks such as carrying guns and ammunition to t...

Heres why chasing happiness won’t make you happy

Heres why chasing happiness won’t make you happy This country was founded partially on the â€Å"pursuit of happiness,† a goal that many people still strive toward on a daily basis. In fact, it seems that people seek constant joy even when they aren’t sure what happiness looks like for their individual lives. Are you so keen on chasing a foggy idea of â€Å"happiness† that you forget to live your life? Do you spend your days trying to avoid all pain, all sadness, and all roadblocks? Happiness is not some kind of prey that can be trapped and held onto for a lifetime. Figure out how to have a healthier relationship with the idea of what it means to have a fulfilling life- which isn’t necessarily a 100% happy one.You’ll never know joy if you never know sadness.Understand that positive emotions aren’t the only ones that make us human. We need the negative ones for balance. Constant happiness would prevent you from accessing the many other emotions that live below your bubbly, Insta-worthy surfa ce. Remember that these other- sometimes undesirable- emotions are often lead to the most productivity. Overcoming challenges can only add to your quality of life, so don’t ignore them! Swim into the current, learn life lessons, and come out a better person.There’s no finish line.The minute you start chasing happiness (or the idea of happiness you have in your head) is the moment you doom yourself never to reach it. Think of happiness more as an activity than a pursuit. You can’t win it and move on, like a prize at the end of a long race. Rather, you cultivate it gently and slowly over the course of your whole life. You learn to discover the people, achievements, and hobbies that bring you joy in the thick of other, more negative feelings and realities of life.Happiness does not equal achievement.You may think if you just keep doing, doing, doing and earning, earning, earning and winning, winning, winning, that happiness will be automatic. But it isn’t ne cessarily equated to success. You will feel great pride with your biggest achievements, but this isn’t the only path to happiness. And excessive pride can lead to selfishness and greed. Stop focusing so hard on your personal advancement and focus on what kind of person you are within every interaction instead.You can’t ever be 100% happy.There will always be something going on in your life that’s unpleasant. Nobody’s life is perfect. Just focus on the positive, feel the emotions you need to process the negative, and remember that happiness isn’t a zero sum game. It’s possible to be mostly happy most of the time. Just don’t try to be perfectly happy all of the time.If you leave a window open for happiness, you’ll find that it finds you fairly easily. Stop to enjoy the little things. Practice more mindfulness. Take joy in the small, the pleasant, the minutiae of your life. Let your cup fill up slowly, by tiny increments, rather t han waiting for one big flood to do it for you.

CT scan protoclos at RMC HOSPITAL Essay Example | Topics and Well Written Essays - 3250 words

CT scan protoclos at RMC HOSPITAL - Essay Example Single-slice helical CT scanners were introduced in the 1980's and multislice CT scanners in the 1990's, which allows a larger section of the body to be scanned in a smaller period of time (Wesolowski, 2005). From the practical perspective, the benefits of CTs are immense. However, CT scans involve higher doses of radiation than the conventional x-ray procedure (Smith-Bindman et al, 2009). CT contributes a large dose towards medical radiation, and is the main source of man- made radiation excluding natural background radiation (Wiest, 2002). There is concern about the exposure of radiation in children and adult population and the subsequent long-term cancer risks. CT procedures cause high doses of radiation to be absorbed through the skin, in the range of 20-30 mGY (2-3 rads) (Wiest, 2002). There is greater concern for the pediatric population because they are more sensitive to radiation exposure than the adult population (Brenner, 2007). Children are more prone to exposure because they have a larger proportion of dividing cells and the tissues of children are up to 10 times more radiosensitive than adults (Brenner, 2007). Chwals et al., found that CT examinations of the head, abdomen an d pelvis routinely performed in pediatric trauma patients exposed them to 50 times the standard yearly dose of background ionizing radiation (Chwals, 2008). Radiation exposure in the adult population is low but still a concern. Broder suggests that in adults, it reaches its threshold in the 40's and then slowly decreases (Broder, 2006). Due to the repetitive radiation exposure and adverse effects associated with it, the operators of CT are expected to possess a concrete knowledge and practical understanding how to reduce the radiation dose patients receive to acceptable minimum (Manghat et al, 2005). Similar concerns regarding radiation exposure and cancer risks have propelled the medical community to implement protocols to lower the radiation dose in children, by adjusting the machine settings without compromising important information (Brenner, 2007). Other measures include reducing repeat CTs and decreasing unnecessary CTs by ensuring that any additional CTs ordered by a physician will only benefit the patient (Brenner, 2007). According to Manghat et al (2005), CT operators can utilize the variety of strategies to reduce radiation exposure such as the use of bismuth shields to protect organs sensitive to radiation, adjusting the machine settings using automatic exposure control (AEC), the tube voltage (kVp) reduc tion, decreasing the pitch and the tube current-time product (mAs). Practically, educating doctors regarding the risks associated with radiation is an important factor to allow physicians to make informed decisions when considering radiological tests (Thomas, 2006). Lee and colleagues highlighted this in a study that found 75% of Emergency Department (ED) physicians and radiologists underestimated the risks associated with radiation from CT examinations (Thomas, 2006). Recognition of the potential cancer risks by the medical community has pressed CT manufactures to implement programs to allow adjustment of the dose with respect to the child's body mass (Chwals, 2008). As of 2003, the majority of hospitals in developed countries reported implementing some programs to reduce radiation exposure in children, though still many hospitals have yet to implement these changes

A Critical Examination of Business Set Up Opportunities in USA from A Essay

A Critical Examination of Business Set Up Opportunities in USA from A Company Perspective - Essay Example A number of forces drive organizations into expanding their operations to the foreign markets. Increased competition in the local and foreign markets as well as reduced trade barriers are some of the factors. The international business environment is quite dynamic and a business organization that has to survive in its international operations has to respond to the changes. The strategic business planning to manage this dynamics involves an examination of the bargaining power of the buyers, the bargaining power of the suppliers, the magnitude of rivalry, the other product or service substitutes, or the threats of other new entries into the market. The vending business is not a new practice in the United States, the first machine of this kind being developed as early as the late nineteenth century. The changing patterns are observed in the quality and types of products offered as well as improvement in the vending machines to ensure security and efficiency. Most recently, there have be en shifts towards high capacity vending machines that can vend healthy juices, yoghurt, fresh fruits, or vegetables. Investment in the healthy vending machine can be incredible in the contemporary society if proper strategic planning and management is carried out. The vending machine business is quite appealing to many individuals in the contemporary markets. The business has several associated benefits to the investor. It is characterized by immediate cash flows, all-cash business (no debts or accounts receivable), can operate 24 hours a day everyday, and it needs little expertise in business management or sales and marketing . The clients in this industry require quick service and ‘demand immediate result making fast food too slow. [The] vending machines provide an affordable quick snack’ (Vending Man, 2011b). The clients give more value to healthy vending that produces healthy foods and with no negative long-term effects on the health of the clients. The business is a fun industry that can generate high returns with little investment since it requires few employees (Vending Man, 201 1a). An individual can supply and manage millions of these machines at different locations with the little task of putting in food occasionally, after every few weeks. This report focuses on these opportunities and the establishment strategy for vending machine business in the US market. The socio-political and economic factors in the US market as well as the business strategy to be employed in this business are illustrated. The US market- Environmental analysis The factors external to our organization like laws and regulations in another country, the country’s economic profile, national culture, and market competition affect the decision to establish business in the country (Mead, 2005). Economic analysis The United States is among the countries that suffered the financial crisis and the resulting economic problems that have been experienced globally (Jickling, 2010). Nonetheless, the Federal Reserve and other government agencies like the US Treasury have shown relentless ef forts to restore the situation through improving the financial systems (Marshall, 2009). It is then likely that the buying ability of the US citizens will be improved giving hope for a new business opportunity. Socio-cultural influence The socio-cultural factors in the country also favor the investment in food industry with focus on healthy eating habits. The consumption of soft drinks has been high in the United States in the past and yet these foods have negative impacts on the consumer heath (Jacobson, 1999). The soft drinks add unnecessary calories to the diet and

Developing a Hypothesis

Developing a Hypothesis Definitions of hypothesis: The hypothesis is outlined as following: â€Å"Hypotheses square measure single tentative guesses, smart hunches –assumed to be used in fashioning theory or coming up with experiments supposed to tend an immediate experimental take a look at once possible†. (Eric Rogers, 1966) â€Å"A hypothesis may be a suppositious statement of the relation between 2 or additional variables†. (Kerlinger, 1956) â€Å"Hypothesis may be a formal statement that presents the expected relationship between AN freelance and variable quantity.†(Creswell, 1994) Hypothesis is that the main a part of analysis. its vital because it suggests new ways in which of doing the analysis. typically experiments square measure solely conduct to check a hypothesis. Decision-makers typically face things whereby theyre curious about testing hypotheses on the premise of accessible info so take choices on the premise of such testing. In scientific discipline, wherever direct information of population parameter(s) is rare, hypothesis testing is that the typically used strategy for deciding whether or not a sample information provide such support for a hypothesis that generalisation is created. so hypothesis testing permits U.S.A. to form chance statements concerning population parameter(s). The hypothesis might not be tried completely, however in follow its accepted if its withstood a essential testing. Before we have a tendency to make a case for however hypotheses square measure tested through totally different tests meant for the aim, itll be acceptable to elucidate clearly the that means of a hypothesis and also the connected ideas for higher world organisation derstanding of the hypothesis testing techniques. WHAT IS A HYPOTHESIS? Ordinarily, once one talks concerning hypothesis, one merely suggests that a mere assumption or some supposition  to be tried or disproved. except for a research worker hypothesis may be a formal question that he intends to  resolve. so a hypothesis is also outlined as a proposition or a group of proposition set forth as AN  explanation for the prevalence of some such cluster of phenomena either declared simply as a  provisional conjecture to guide some investigation or accepted as extremely probable within the lightweight of  established facts. very often a research hypothesis may be a prophetical statement, capable of being tested  by scientific ways, that relates AN variable to some variable quantity. for instance,  consider statements just like the following ones: â€Å"Students WHO receive counseling can show a larger increase in creative thinking than students not  receiving counselling† Or  Ã¢â‚¬Å"the automobile A is performing arts furthermore as automobile B.† These square measure hypotheses capable of being objectively verified and tested. Thus, we have a tendency to could conclude that  a hypothesis states what we have a tendency to square measure searching for and its a proposition which may be place to a take a look at to  determine its validity. Characteristics of hypothesis: Hypothesis should possess the subsequent characteristics: (i) Hypothesis ought to be clear and precise. If the hypothesis isnt clear and precise, the  inferences drawn on its basis cant be taken as reliable. (ii) Hypothesis ought to be capable of being tested. during a swamp of untestable hypotheses, many  a time the analysis programmes have over-involved. Some previous study is also done by  researcher so as to form hypothesis a testable one. A hypothesis â€Å"is testable if alternative  deductions is made up of it that, in turn, is confirmed or disproved by observation.†1 (iii) Hypothesis ought to state relationship between variables, if it happens to be a relative  hypothesis. (iv) Hypothesis ought to be restricted in scope and should be specific. A research worker should keep in mind  that narrower hypotheses square measure typically additional testable and he ought to develop such hypotheses. (v) Hypothesis ought to be explicit as so much as doable in most straightforward terms in order that identical is  easily comprehensible by all involved. however one should keep in mind that simplicity of hypothesis  has nothing to try to to with its significance. (vi) Hypothesis ought to be in keeping with most illustrious facts i.e., it should be in keeping with a  substantial body of established facts. In alternative words, it ought to be one that judges settle for  as being the foremost possible. (vii) Hypothesis ought to be amenable to testing inside an affordable time. One shouldnt use  even a superb hypothesis, if identical cant be tested in affordable time for one  cannot pay a life-time aggregation information to check it. (viii) Hypothesis should make a case for the facts that gave rise to the necessity for rationalization. This means  that by exploitation the hypothesis and alternative illustrious and accepted generalizations, one ought to be  able to deduce the initial downside condition. so hypothesis should truly make a case for what  it claims to explain; it ought to have empirical reference. The null hypothesisrepresents a theory that has been hints, either as a result of its believed to be true or as a result of its to be used asa basis for argument, however has not been tried. Has serious outcome if incorrect call is made! The alternative hypothesisis an announcement of what a hypothesis take a look at is about up to ascertain. Opposite of Null Hypothesis. Only reached if H0is rejected. Frequently â€Å"alternative†is actual desired conclusion of the researcher! The method of hypothesis testing is summarized in four steps. we are going to describe every of those four steps in larger detail in Section eight.2. 1. To begin, we have a tendency to establish a hypothesis or claim that we have a tendency to feel ought to be tested. for instance, wed need to check the claim that the mean range of hours that kids within the us watch TV is three hours. 2. We have a tendency to choose a criterion upon that we have a tendency to decide that the claim being tested is true or not. for instance, the claim is that kids watch three hours of TV per week. Most samples we have a tendency to choose ought to have a mean near or up to  3 hours if the claim we have a tendency to square measure testing is true. therefore at what purpose can we decide that the discrepancy between the sample mean and three is therefore massive that the claim  we square measure testing is probably going not true? we have a tendency to answer this question during this step of hypothesis testing. 3. Choose a random sample from the population and live the sample mean. for instance, we have a tendency to might choose twenty kids and live the time unit (in hours) that they watch TV per week. 4. Compare what we have a tendency to observe within the sample to what we have a tendency to expect to watch if  the claim we have a tendency to square measure testing is true. we have a tendency to expect the sample mean to be around  3 hours. If the discrepancy between the sample mean and population mean is tiny, then {we will|well|we square measure going to} possible decide that the claim we have a tendency to are testing is so true. If the discrepancy is simply too giant, then we are going to possible conceive to reject the claim as being not true. The method of hypothesis testing is summarized in four steps. we are going to describe every of those four steps in larger detail in Section eight.2. 1. To begin, we have a tendency to establish a hypothesis or claim that we have a tendency to feel ought to be tested. for instance, wed need to check the claim that the mean range of hours that kids within the us watch TV is three hours. 2. we have a tendency to choose a criterion upon that we have a tendency to decide that the claim being tested is true or not. for instance, the claim is that kids watch three hours of TV per week. Most samples we have a tendency to choose ought to have a mean near or up to  3 hours if the claim we have a tendency to square measure testing is true. therefore at what purpose can we decide that the discrepancy between the sample mean and three is therefore massive that the claim  we square measure testing is probably going not true? we have a tendency to answer this question during this step of hypothesis testing. 3. choose a random sample from the population and live the sample mean. for instance, we have a tendency to might choose twenty kids and live the time unit (in hours) that they watch TV per week. 4. Compare what we have a tendency to observe within the sample to what we have a tendency to expect to watch if  the claim we have a tendency to square measure testing is true. we have a tendency to expect the sample mean to be around  3 hours. If the discrepancy between the sample mean and population mean is tiny, then {we will|well|we square measure going to} possible decide that the claim we have a tendency to are testing is so true. If the discrepancy is simply too giant, then we are going to possible conceive to reject the claim as being not true. Step 2: Set the standards for a choice. to line the standards for a choice, we have a tendency to state the extent of significance for a take a look at. this can be the same as the criterion that jurors use during a criminal trial. Jurors decide whether or not the proof bestowed shows guilt on the far side an affordable doubt (this is that the criterion). Likewise, in hypothesis testing, we have a tendency to collect information to point out that the null hypothesis isnt true, supported the probability of choosing a sample mean from a population (the likelihood is that the criterion). The probability or level of significance is often set at five-hitter in activity analysis studies. once the chance of getting a sample mean is a smaller amount than five-hitter if the null hypothesis were true, then we have a tendency to conclude that the sample we have a tendency to designated is simply too unlikely and then we have a tendency to reject the null hypothesis. Level of significance, or significance level, refers to a criterion of judgment upon that a choice is created relating to the worth explicit during a null hypothesis. The criterion relies on the chance of getting a data point measured during a sample if the worth explicit within the null hypothesis were true. In activity science, the criterion or level of significance is often set at five-hitter. once the chance of getting a sample mean is a smaller amount than five-hitter if the null hypothesis were true, then we have a tendency to reject the worth explicit within the null hypothesis. The alternative hypothesis establishes wherever to position the extent of significance. keep in mind that we all know that the sample mean can equal the population mean on the average if the null hypothesis is true. All alternative doable values of the sample mean square measure commonly distributed (central limit theorem). The empirical rule tells U.S.A. that a minimum of ninety fifth of all sample suggests that fall inside concerning two customary deviations (SD) of the population mean, that means that theres but a five-hitter chance of getting a  sample mean thats on the far side two South Dakota from the population mean. For the youngsters  watching TV example, we are able to seek for the chance of getting a sample mean  beyond two South Dakota within the higher tail (greater than 3), the lower tail (less than 3), or both  tails (not up to 3). Figure 8.2 shows that the choice hypothesis is employed to  determine that tail or tails to position the extent of significance for a hypothesis take a look at. Step 3: reckon the take a look at data point. Suppose we have a tendency to live a sample mean up to  4 hours per week that kids watch TV. to form a choice, wed like to judge  how possible this sample outcome is, if the population mean explicit by the null  hypothesis (3 hours per week) is true. we have a tendency to use a take a look at data point to work out this  likelihood. Specifically, a take a look at data point tells U.S.A. however so much, or what number customary  deviations, a sample mean is from the population mean. The larger the worth of the  test data point, the any the space, or range of normal deviations, a sample  mean is from the population mean explicit within the null hypothesis. the worth of the  test data point is employed to form a choice in Step four. The take a look at data point may be a mathematical formula that permits researchers to  determine the probability of getting sample outcomes if the null hypothesis  were true. the worth of the take a look at data point is employed to form a choice relating to  the null hypothesis. Step 4: build a choice. we have a tendency to use the worth of the take a look at data point to form a choice  about the null hypothesis. the choice relies on the chance of getting a  sample mean, only if the worth explicit within the null hypothesis is true. If the chance of getting a sample mean is a smaller amount than five-hitter once the null hypothesis is true, then the choice is to reject the null hypothesis. If the chance of getting a sample mean is bigger than five-hitter once the null hypothesis is true, then the choice is to retain the null hypothesis. In sum, there square measure 2 choices a research worker will make: 1. Reject the null hypothesis. The sample mean is related to an occasional chance of prevalence once the null hypothesis is true. 2. Retain the null hypothesis. The sample mean is related to a high chance of prevalence once the null hypothesis is true. The chance of getting a sample mean, only if the worth explicit within the null hypothesis is true, is explicit by the p worth. The p worth may be a probability: It varies between zero and one and may neer be negative. In Step 2, we have a tendency to explicit the criterion or chance of getting a sample mean at that purpose we are going to conceive to reject the worth explicit within the null hypothesis, that is often set at five-hitter in activity analysis. to form a choice, we have a tendency to compare the p worth to the criterion we have a tendency to set in Step two. A p worth is that the chance of getting a sample outcome, only if the worth explicit within the null hypothesis is true. The p worth for getting a sample outcome is compared to the extent of significance. Significance, or applied mathematics significance, describes a choice created regarding a worth explicit within the null hypothesis. once the null hypothesis is rejected, we have a tendency to reach significance. once the null hypothesis is preserved, we have a tendency to fail to achieve significance. When the p worth is a smaller amount than five-hitter (p < .05), we have a tendency to reject the null hypothesis. we are going to talk over with p < .05 because the criterion for deciding to reject the null hypothesis, though note that once p = .05, the choice is additionally to reject the null hypothesis. When the  p worth is bigger than five-hitter (p > .05), we have a tendency to retain the null hypothesis. the choice to reject or retain the null hypothesis is named significance.
