A Beginnerââ¬â¢s Guide to Alliteration
A Beginnerââ¬â¢s Guide to Alliteration A Beginnerââ¬â¢s Guide to Alliteration A little alliteration can liven up even the limpest literature. So if youââ¬â¢re not sure what this is, or why that first sentence is full of ââ¬Å"Lâ⬠words, you may want to check out our guide. Weââ¬â¢ll also look at two related poetic techniques: consonance and assonance. What Is Alliteration? Alliteration occurs when we use the same sound repeatedly in a sentence. This is often at the start of a word, but it can also be at the start of a stressed syllable in a word. You may have seen alliteration used in poetry, particularly in tongue twisters. For example, the nursery rhyme ââ¬Å"Peter Piperâ⬠uses the letter ââ¬Å"pâ⬠alliteratively: Peter Piper picked a peck of pickled peppers. A peck of pickled peppers Peter Piper picked. If Peter Piper picked a peck of pickled peppers, Wheres the peck of pickled peppers Peter Piper picked? This is a case of alliteration where the whole point is to be tricky to say! Why Use Alliteration in Poetry? Usually, poets use alliteration to create a mood in a poem or to give it rhythm. For example, take the first stanza of Edgar Allen Poeââ¬â¢s ââ¬Å"The Ravenâ⬠: Once upon a midnight dreary, while I pondered, weak and weary, Over many a quaint and curious volume of forgotten lore- à à à While I nodded, nearly napping, suddenly there came a tapping, As of some one gently rapping, rapping at my chamber door. ââ¬Å"ââ¬â¢Tis some visitor,â⬠I muttered, ââ¬Å"tapping at my chamber door- à à à à à à à à à à à Only this and nothing more.â⬠Here, we have multiple cases of alliteration that combine with the rhyme scheme to give the text a strong rhythm and emphasize certain words. Poe does the same throughout the poem. Sometimes, you can also use alliteration to evoke a mood or image. A good example of this is sibilance, which involves the repetition of soft ââ¬Å"Sâ⬠sounds: The snake slithered silently across the sand. Here, the repetition of ââ¬Å"Sâ⬠sounds like the hiss of a snake. As such, the sound of the sentence reinforces the image it describes, like in onomatopoeia. Other Uses of Alliteration Many people use alliteration to make language memorable, including in: Company and brand names (e.g., Coca Cola, Dunkinââ¬â¢ Donuts) Slogans (e.g., Jaguarââ¬â¢s ââ¬Å"Donââ¬â¢t dream it. Drive it.â⬠) Titles of books, movies, etc. (e.g., Black Beauty, Doctor Doolittle) Character names (e.g., Mickey Mouse, Peter Parker) In all these cases, the repetition makes the phrase catchier and more striking. Assonance and Consonance Finally, we should look at two techniques related to alliteration: assonance and consonance. These both involve repetition of sounds, but theyââ¬â¢re not quite the same as alliteration. Assonance is repetition of vowel sounds. For example, the repetition of ââ¬Å"ooâ⬠in ââ¬Å"Your spooky bassoon went boom as I fell through my stool.â⬠Consonance is repetition of consonant sounds in any part of a word, not just at the start. For instance, ââ¬Å"The vegan dog hugged the ugly frogâ⬠is consonance but not alliteration. This is because the repeated ââ¬Å"Gâ⬠occurs in different parts of the words, not just at the start of stressed syllables. You can use assonance and consonance to make writing more rhythmic or memorable. This is especially common in poetry, but, as with alliteration, it is also effective in other contexts.

The impact of globalization on corporate governance Assignment
The impact of globalization on corporate governance - Assignment Example So corporate governance has now emerged as global responsibility. The effect of global approach to regulate corporate governance is debatable. Criticisms are there that such regulations carry no meanings as big corporate houses have the power to manipulate even the international policies owing to their size and their influence in markets. In recent times agencies such as Organization for Economic Corporation and Development (OECD) and Indian Labor Organization (ILO) have prepared a set of guidelines so as to regulate corporate governance. The activities and behavior of business houses are checked upon mainly on issues like environmental protection, human rights, safety and corruption. In developing countries through effective corporate governance corporations can contribute largely in labor and environmental conditions of the country. Considering all these facts one can rate global approach to regulation highly important for corporate governance and the paper intends to addresses thi s issue through a series of case studies and analysis. Corporate governance helps companies and economies to bring in new investors and strengthen the foundation. It also makes a firm more competitive by improving its economic performance. Elimination of corruption and financial scandals is considered as the major objective of corporate governance.It has been widely accepted that a written code of conduct helps in improving corporate governance. United Kingdom has adopted such principles for governance in 2003 and has obtained amazing outcomes in 2005. These global rules include ability of mobilizing and monitoring of productive resources and their effective allocation. (Isaksson, 1999). Separate committees should be set up for nomination, compensation and auditing. Transparency of the annual reports and accounting matters is now compulsory as per guidelines. This are now regulated through actuarial information in UK (Regulatory Strategy: Our role and Approach, 2009). The board of directorsââ¬â¢ decision making should only be in favor of fulfilling companyââ¬â¢s interests. The conduct of the directors is very crucial and their decisions matter a lot, especially in turnaround situations. The investors also bear similar responsibilities more in the area of risk management and when voting for vital issues. There is a need for the companies to realize their social and environmental responsibilities (Bowes, 1999). The importance of this global approach for proper conduct is to such an extent that corporate social responsibility has taken the name of globalization of business and economies. National economies have become enormously inter dependant in the areas of trade and finance. In some cases there has also been integration of macroeconomic policies (Guillen, 1999).In Asian countries before such global approach there have reports against the companies for unfavorable working conditions and employment of child labor. For developing countries overlapping public and private sector have prevented good corporate gove rnance in the past (Kostyuk, Braendle & Apreda, 2007) Global agencies have worked quite hard in regulating

Bullying in Schools Essay Example | Topics and Well Written Essays - 3000 words
Bullying in Schools - Essay Example This study declares that victims of bullying in school have been shown to manifest a higher risk of social maladjustment. The good news is that because bullying behavior typically occurs on a recurrent basis between two individuals who know each other, it is one of the few conditions that can also often be identified and prevented, perhaps with the result of a reduction in criminal behavior among adults.à However, before teachers and administrators can reduce the long-term effects caused by bullying schools, they must first be informed as to the prevalence, development and identification of the problem to instill in them an appreciation of the seriousness of the problem and then be provided with knowledge of those approaches that have proven to reduce these behaviors among schoolchildren.à This research stresses thatà the term ââ¬Ëbullyingââ¬â¢ is used to denote a specific behavior pattern statistically occurring most often among boys but that can occur among girls as we ll.à ââ¬Å"Bullying is characterized by bigger and stronger youngsters ââ¬Ëvictimizingââ¬â¢ their peers through the repeated use of negative actions, such as physical, verbal or relational aggressionâ⬠.à Despite noted differences in bullying behavior noted among grade levels, other research determined that the patterns of bullying and the social rejection that results from this type of behavior are established early.à A child with overly aggressive tendencies will quickly become labeled as a bully and will be socially rejected from the group, contributing to further disruptive behavior.

Business report Essay Example | Topics and Well Written Essays - 1250 words
Business report - Essay Example Essentially a service sector organization, Woolworths purchases its goods mostly from Australian farmers and since most purchases are domestic, their products are fresh. The report would focus on how such a successful firm can enter the Indian markets given that there is currently a retail boom in India as well (Ramaswamy and Namakumari 2009, 105). Since Woolworths is into fresh food, it is imperative that procuring the food items from Australia and shipping the same to India would not make sense. Thus, the best option to avail is to procure it from the Indian farmers and sell it in the same country, though the model they should follow has to be reviewed thoroughly in order to make a fitment between the demands of the Indian market and what Woolworths would like to offer. In the case of Woolworths, since the primary product offering is fresh food items as well as processed food, it is obvious that the basic requirement is not technological or even manufacturing plants but a sound inf rastructure that would ensure strong linkages with the markets ââ¬â both of the farmers who are to supply the produce on a regular basis as well as the customers who are to buy the same. However, the main focus of Woolworths should be on value addition to those products. The report would focus on the macro environmental factors that are likely to come into play if Woolworths were to expand into the Indian retail markets. Thus, the report would start with the PESTL analysis and then move on to the specifics of the firm by doing a SWOT analysis of Woolworths. Having done these two analyses, the recommendations, whatever suitable for Woolworths, would be made in order to make the expansion project a success. PESTL Analysis The first analysis that should be performed is the PESTEL Analysis, which is defined as amalgamation of various macro-environmental forces that drive the organizationââ¬â¢s performance and comprises the political, economic, sociological, technological, ecologi cal and legal forces (Viardot 2004). Furthermore, ââ¬Å"it assists companies in the selection of attractive markets and the appropriate entry modeâ⬠(Aubert and Frigstad 2007). Political India is typically a politically stable nation that has been trying to attract FDI, and more so in retail. This should prove to be an advantage so far as the political environment of Woolworths in India is concerned (Krafft and Mantrala 2010, 130). Even Asian countries like India and China have slowly opened their doors to globalization, thereby welcoming conglomerates like Woolworths. In the wake of globalization, regulation and tax policies and FDI policies are to be relaxed considerably and even China and India have deregulated and delicensed various products making it further congenial for Woolworths to operate. However, various quarters of the political sector has exhibited stiff resistance to FDI in retail and especially multi brand retail (Datt 2008, 178). It is clear that since the gov ernment is keen on investment in FDI, thus the environment would work to the benefit of Woolworths in India. Legal The legal environment of Woolworths in India again points out to some of the encouraging features of increased investment in FDI on the part of the government as well as other legalities that may have to be fulfilled while opening retail outlets in India.

Conventional in situ construction
Conventional in situ construction 2.1 Introduction In architecture and building, in situ refers to construction which is carried out on the building site using raw materials. In-situ is most commonly a mixture of aggregate (known as builders mix) blended with portland cement and clean water, that is free of oils, acid and others. Portland cement is made from lime, silica, alumina and gypsum with the raw materials being readily available throughout the country. Aggregate meanwhile is most commonly sand, gravel and crushed stone and constitutes 60 to 75pc of the volume of most concretes. In-situ concrete is strong, durable, stable, readily available and relatively economic in terms of construction and life time maintenance. It is the ideal structural material, in building sites that have difficult access. Other qualities that make it an ideal construction medium include the ability to control of form and shape, the enclosure of space and structure in one material, its compatibilty with most other materials, the ability to form integral surface finishes and colour of its compatibilty with most other materials. In-situ concrete structure usually used in industrial and commercial service industry such as school,hospital and hotel.The basic form of in-situ concrete structure are columns, beams, walls and floor. Compare that withprefabricatedconstruction, in which building components are made in a factory and then transported to the building site for assembly unlike insitu method of construction. Conventional building method or in situ construction method, is also defined as components of the building that are made at site through the processes of timber or plywood formwork installation, steel reinforcement, and cast in situ. Conventional buildings are mostly built of reinforced concrete frames. The traditional construction method uses wooden formwork. It is much more costly for construction which includes labour, raw material,transportation and low speed of construction time. This system is suitable for a country where unskilled labour is limited. There is no heavy machinery or high technolog y involved compare to precast method. 2.2 Advantages of using in situ The objective of an in situ method is to eliminate and reduce the traditional site-based trades like traditional timber formwork, brickwork, plastering and to reduce labour content. By using in situ method, alteration can be made at the last minute, design can be proceed as the structure is built and the rates of the production can be fast. 2.3 Disadvantages of using in situ However, conventional in-situ construction method also have their own disadvantages. It will lead to the higher amount of wastage compare to precast method. For example, in term of mixture of cement,sand and aggregates. It also require all activities involve high labour and plant on site. Besides,construction is also influenced by the weather and the reinforcement and formwork tend to be labour intensive.

Military Essay -- Department of Defense, ASVAB
According to the DOD, (2011) the department of defense doesnââ¬â¢t allow any third party anything in association with the military or any of itââ¬â¢s governmental functioning counter parts ala... national guards, reserves, commission corpse, naval reserves , marines reserves etcâ⬠¦ DODD rule 8750 insures that all military servicemen must be certified in their prospective fields and be proficient in their MOS field after boot camp and AIT. (DoDD, 2011) To become a soldier one must first visit a local recruiting office; there a person may engage in talks with a recruiter, the recruiterââ¬â¢s main job is to help assess the civilian enquires about their military desires, the recruiter must talk to a recruit and his legal guardian or parents as no one under 18 canââ¬â¢t make decisions for themselves without their parents/ guardians permission. The recruiter then will start the process, one of the recruiterââ¬â¢s first assignments is to get the civilian ASVAB scores from their local high school or if the recruit is from out of town they can be retested on the ASVAB. The ASVAB stands for Armed Services Vocational Aptitude Battery test and it accesses a recruitââ¬â¢s probability for enlistment, military job placement and career exploration after the military. ASVAB scoring is based on (IRT) Item Response Theory, this model is used because it measures the examineeââ¬â¢s ability to be placed on the same scale as everyone else and each test is tailored to a specific ability level needed when the examinee picks their military job. The IRT model uses the (3pl) in which measures a examineeââ¬â¢s level of ability to respond to a individual item or characteristics, especially those characteristics that represents difficulty, discrimination (How an item discriminates among ex... ...any part of the (PRT) theyââ¬â¢ll be giving more intense exercises to perform this is to increase their stamina, and get them ready for the next phase of Army training as each phase last 3 weeks and getââ¬â¢s more intense until the last phase.

Hometown Deli
Hometown Deli Case Study The Hometown Deli was established by your grandfather in 1952 in your hometown. It offers many different kinds of specialized coffees, teas, a full service bakery, homemade soups, sandwiches, and salads. The Deli has been a local hotspot for many years and has served as a community gathering place. Your grandfather recently retired from the business and has asked you to take it over. You are very excited about this opportunity! Unfortunately, business has been steadily declining over the last five years. Although your grandfather was an expert at running the deli, it is outdated.There are no computers in the store and all ordering takes place manually.

Agar Cube Lab Report Essay Example
Agar Cube Lab Report Essay Example Agar Cube Lab Report Paper Agar Cube Lab Report Paper Hypothesis: I expect to find that when the surface area o volume of a cell reaches a certain level, diffusion alone wont be able to supply the cell materials needed, and as single-celled organisms take in and release substances by means of diffusion across the cell membrane, this process limits cell size. I predict that as the rate of diffusion will be too slow to deliver materials to the center of the cell in the larger cells, it could result in cell malfunction. Variables: The independent variables are the dimensions of surface area to volume ratio of the agar cube. (1 CM, 1. CM,CM) The dependent variable, the variable am observing/recording, is the time of diffusion (Noah turns the agar cube pink as it disperses into it). The controlled variables will be keeping the concentrations of the Sodium Hydroxide constant, to use agar jelly from the same batch. Also, theres the room temperature which is kept constant and the room pressure. Materials: 250 ml beaker Measuring tape Dull knife Stirring rod Phenolphthalein agar cubes (xx CM, 1. CM,1 CM) Hydrochloric acid (1 m) Paper towel Ruler Procedure: 1- Obtain agar cubes and hydrochloric acid from your lab instructor. Cut the bubs so that one has a length of 1. 00Ã ±0. 05 CM, another 1. 50Ã ±0. 05 CM, and the 3rd 2. 00Ã ±0. 05 CM. 3- Examine the cubes closely and then place them in the ml beaker. As we can see the cube with the largest surface area and volume has the smallest surface area to volume ratio. If the surface area to volume ratio gets too small, then the substances wont be able to enter the cell fast enough to fuel the reactions, because the surface area controls the rate of the exchange of materials while as the volume grows larger it will need more materials to enter and exit, in a more quicker rate, therefore waste products will start to accumulate within the cell as they will be produced faster than they can be excreted. In addition, the cells will not be able to lose heat fast enough and so may overheat. This was concluded from the experiment, where as the Agar cube dimension were larger, the rate of diffusion was much mallet from the Agar cube with the smaller dimension, where the last had a larger V: AS ratio than the larger cube. Errors and Improvements: Error Improvement Parallax error, resulting in a misreading in volume. This is caused by reading the volume readings from an angle, thus to solve this error, readings must be read at the human eye level, where the meniscus being measured at and the eye, are at the same horizontal level for accurate reading intakes. The measuring cylinders that were used for the HCI were not divided by the same rate of division. Use the same type of cylinders for all trials, like a limerick cylinder to measure the amount of aqueous (HCI ) more accurately. The sizes of the cubes were not exact as mentioned ( Ex: 1 CM is not exact ) and as a result the results obtained may not be very accurate. When cutting, a more precise instrument must be used. If no other instrument is found, a more sharper knife can be used accompanied with a more specific ruler. Injury of the surface of the cubes due to hard stirring by the rod. Stir at a slower rate for a longer time than stirring hard for a little time, in addition to that a thinner rod can be used for stirring.

The Golden Door To America Essays - Demography, Population
The Golden Door To America Essays - Demography, Population The Golden Door To America Writen by Randy j 11/24/00 I wrote this paper for Political Life 1110 Should America Close the Golden Door? America has, is, and will always be a nation of immigrants: the great melting pot. In the years that have passed since Emma Lazarus poem was inscribed on the Statue of Liberty the golden door has seen times when it was open wide and times when it was closed shut to almost all immigrants. Many people tend to look at the present immigration problems as a purely modern dilemma. The truth is America has always struggled with the issue of immigration, both legal and illegal. Changing times however make it imperative that our government re-examine and adjust todays immigration laws to todays standards. Those standards however are not easily defined. All too often the issue of immigration is used as a political tool or is lost in heated moral debates. In any discussion about immigration you will have those who claim it is good for our nation and those who claim it is ruining the nation. More often than not the bottom line in any debate of this sort is m oney; will more or less immigration mean more or less money for those already in America. The moral debates come down to a question of who we are as a nation and how we want the rest of the world to perceive Americans. If this great country was forged and built by immigrants passing through the golden door , then how can this same country turn away new immigrants. The inscription on the Statue of Liberty invites all to enter, yet not all are allowed to enter. Immigration has become a selective process with many gray areas. Now Americans are faced with a new dilemma; the nation must decide not whether it is willing to accept new immigrants, but whether it can afford new immigrants. All new immigrant, both legal and illegal must be considered in this equation. Congress can attempt to ease the burden of legal immigration by passing restrictive laws and only allowing in those who they believe will become self-sufficient. Congress must also find a way to slow the flow of illegal immigrat ion by enforcing the laws already in place. What this paper will attempt to do is bring the immigration issue into perspective. America most certainly has immigration problems but they will not be fixed by eliminating immigration all together. In fact, America will never totally eliminate immigration, because no matter how tightly the door is closed some illegal immigrants will get through. As long as America continues to be seen as a nation of prosperity, opportunity, and freedom there will be those who wish to come to America. Immigrants have always come to America looking for a better life and Americans are always forgetting that their forefathers were once looking for that same life. As a nation there must be a decision on whether immigration is an issue of conscience or economics. History of Immigration Laws Though most Americans see immigration as a modern problem it has been heavily debated since the 19th century. Throughout most of Americas history immigration was seen as a natural process that benefited the nation (Divine 2). Until the 1890s there were no clearly defined policies on immigration. During this time the country started questioning the economic benefits of more immigrants, so things have note changed in that respect. In May 1921, the first bill in American history restricted European immigration and created the quota system (Divine 5). This turn toward restriction could be justified by the downward turn in the economy. Who could argue for more immigrants when the nations own citizens couldnt find work. The slowing economy and the spirit of intense nationalism in the United States at this time made immigration a hot topic (Divine 23). After the depression hit everyone was in agreement that there was a need to limit immigration, of course the extent of those limits were not easily agreed upon (Divine 77). World War II brought with it a new set of immigrants, and eventually the passing of the Displaced Persons Act of 1947. This allowed immigr ants, displaced by the war to enter

Emphysema lung disease Essay Example | Topics and Well Written Essays - 750 words
Emphysema lung disease - Essay Example Chronic exposure to cigarette smoke decreased elasticity of the lungs and destroys the alveoli. Another cause of emphysema is deficiency of alpha-1-antitrypsin, a substance that fights a destructive enzyme in the lungs called trypsin. An alpha-1-antitrypsin deficient person cannot fight the destructive effects of trypsin and the lung is slowly destroyed. Though the role of genetics in the development of emphysema is unclear, alpha-1-antitrypsin deficiency may be inherited. Other causes of emphysema are air pollution, abnormal airway reactivity, sex and old age. Air pollution has similar effect on the lungs like cigarette smoke. The pollutants will inflame the airways and destroy the lung tissues. Abnormal airway reactivity, such as bronchial asthma, can lead to emphysema. The differences between male and female hormones are suspected to make more men develop emphysema than women. It is also found that lung function normally declines with age, that lung tissues are destroyed as one gets old and this condition will lead to emphysema. The most common symptom of emphysema is shortness of breath. Due to the collapse of the chest wall, a person with emphysema has to struggle to exhale completely because his airways are close when exhaling. In the advance case of emphysema, a person may engage in "purse-lipped breathing" wherein the person purse his lips, leaving only a small opening. When exhaling, the lips block the flow of air and increase pressure in the collapsed airways. Since air is trapped behind obstructed airways, a person with emphysema may develop a "barrel chest" where the distance from the chest to the back becomes more pronounced. Other symptoms are cough and wheezing and decrease in tolerance for exercise.When experiencing shortness of breath, decrease in the ability to exercise or perform daily activities, a persistent cough or wheezing, consult your doctor since these may be indicative of other diseases such as heart problem and other lung diseases. The doctor can also help in formulating a plan to quit smoking. Watch out if the lips, tongue, fingernails, or skin turn blue since these indicate cyanosis or severe worsening of your lung condition. If these symptoms are seen, rush to the hospital's emergency department. If the doctor suspects emphysema in a patient, he will recommend physical examination, with particular focus on breathing sounds, heart sounds, and general physical appearance. A number of tests may be ordered or performed such as chest x-ray, lung function tests, bloods tests. These tests will gauge the extent of the disease, the remaining lung function, and the presence of lung infections. Looking at the chest x-ray results, the doctor can identify changes in the lungs that may indicate emphysema, detect presence of an infection or a mass in the lung (such as a tumor). The lung function tests will give specific information on how the lungs are working mechanically. In the lung function test, the patient is made to breathe into a tube that is connected to a computer or some other monitoring device. The lung function tests measure how much air the lungs can hold, how quickly the lungs can expel air during expiration, and how much reserve capacity the lungs have for increased demand such as during exercise. The blood tests will check white blood cell count, which in turn indicates an acute
