Radiation Definition and Examples

Radiation and radioactivity are two easily confused concepts. Just remember, a substance does not need to be radioactive to emit radiation. Lets look at the definition of radiation and see how it differs from radioactivity. Radiation Definition Radiation is the emission and propagation of energy in the form of waves, rays or particles. There are three main types of radiation: Non-ionizing radiation: This is the release of energy from the lower-energy region of the electromagnetic spectrum. Sources of non-ionizing radiation include light, radio, microwaves, infrared (heat), and ultraviolet light.Ionizing radiation: This is radiation with sufficient energy to remove an electron from an atomic orbital, forming an ion. Ionizing radiation includes x-ray, gamma rays, alpha particles, and beta particles.Neutrons: Neutrons are particles found in the atomic nucleus. When they break away from the nucleus, they have energy and act as radiation. Examples of Radiation Radiation includes emanation of any portion of the electromagnetic spectrum, plus it includes the release of particles. Examples include: A burning candle emits radiation in the form of heat and light.The Sun emits radiation in the form of light, heat, and particles.Uranium-238 decaying into Thorium-234 emits radiation in the form of alpha particles.Electrons dropping from one energy state to a lower state emit radiation in the form of a photon. Difference Between Radiation and Radioactivity Radiation is the release of energy, whether it takes the form of waves or particles. Radioactivity refers to the decay or splitting of an atomic nucleus. A radioactive material releases radiation when it decays. Examples of decay include alpha decay, beta decay, gamma decay, neutron release, and spontaneous fission. All radioactive isotopes release radiation, but not all radiation comes from radioactivity.

An Education In Language - 3188 Words

An Education in Language by R. RODRIGUEZ Born in 1944 in San Francisco, California, Richard Rodriguez grew up in a home in which Spanish was the first language; consequently, like millions of Americans he learned English as his second language. As a child, Rodriguez experienced an oftimes painful struggle to master English, which he calls his â€Å"public† language. As an adult, he attended Stanford University in California and Columbia University in New York, following which he did graduate work at the Warburg Institute in London and the Uni ­versity of California at Berkeley. Best known as a writer and lecturer, Rodriguez cur ­rently lives in San Francisco. Some educationists have recently told me that I received a very bad education. They†¦show more content†¦(No longer so desperate for the consolation of intimacy.) My brothers and I didn’t rush home after school. Even our parents grew easier in public, following the Americanization of their children. My mother started referring to neighbors by name. My father continued to speak about gringos, but the word was no longer charged with bitterness and suspicion. Hearing it sometimes, I wasn’t even sure if my father was say ­ing the Spanish word, gringo, or saying, gringo, in English. Our house was no longer noisy. And for that I blamed my mother and father, since they had encouraged our classroom success. I flaunted my second-grade knowledge as a kind of punishment. (â€Å"Two negatives make a positive!†) But this anger was spent after several months, replaced by a feeling of guilt as school became more and more important to me. Increasingly successful in c lass, I would come home a troubled son, aware that education was making me different from my parents. Sadly I would listen as my mother or father tried unsuccessfully (laughing self-consciously) to help my brothers with homework assignments. My teachers became the new figures of authority in my life. I began imitating their accents. I trusted their every direction. Each book they told me to read, I read and then waited for them to tell me which books I enjoyed. Their most casual opinions I adopt ­ed. I stayed after school â€Å"to help† – to get their attention.

Human Rights Analysis Free Answers to Students-Myassignmenthelp

Question: Discuss about the Human Rights Analysis. Answer: The following essay is going to address the issue of human rights as it has been discussed in the provided case study. The topic seems to be hovering around the issues on double standard and hate speech. Since the4 social complexity is rising vehemently, and the social activists are on the mode of such understanding level, it has the opportunity of the senses which has been taking part in all sorts of formative activism. The essay has two parts. The first part is going to address the issues as indicated in the most respective genre of human rights and its generalising powers. It is going to be a discussion thread and the second part is going to analyse the details of the provided case study. There are certain level of critical understanding of the case analysis on double standard and hate speech. These two issues are extremely violent and conflicting while dealing with human being and his social interference. Creation of Thread Discussion: In general sense, threads are created in order to design a conversation level that has discussions on the topic and reply according to the concept building process. Following is the structure of thread that has constituted posting details on argumentative discussion on the double standard and human rights related issues. Student 1 Initial response to the Case Topic: While responding to the topic of discussion I have determined to carry on with the fact that my understanding on the subject hate speech and double standards is quite negative. I do not think that a person should be engaged in the position to raise his or her voice on the basis of religion. There are much more serious issues that can be dealt with. I have recently gone through two of the videos that portrayed outrageous speech of two different religious preachers and practitioners from two major Asian countries Bangladesh and India. Both of the countries have been in news for recent days because of constant growth of some sensitive issues regarding religious difference and conflict. Constant growth of religious difference and hatred between two of the major Asian religions- Hinduism and Islam has been quite outrageous in recent days when an Islamic clergy from Bangladesh disgraced his religious compatriot for attending so called Hindu festival poila baishakh- the New Year for the Be ngali community. On the other hand, several places in India is frequented by the Hindu armed forces who are supposed to celebrate Ram Navami- another Hindu festival. In these two scattered case, hate speech against each other has raised agitation among people against the other religions. Is this a state of country or a world that is called democracy? I do not think so because the entire world seems to be moving backward and people are sitting without a voice against the vehement practice. Reply from Student 2: In this case I have a say that most of the religious factors are not responsible. I think that most of the religious figures- especially the extremists are not ready to acknowledge the fair existence of the other religions. Religion is no longer limited to human race. It has rather extended its view to racism and gender bias. Hence we face such complexity in the modern age. How could one forget the Christian rage upon the Jews during Nazi period? Student 1 Reply: You may seem right, though there is no direct provision of involvement in religious aspect. Student 2 Reply: I do not agree to it at all because the first and the foremost cause of such hate speech is the counter version or reverse attack of what they have been undergoing for decades and centuries. People have a mindset that a particular religious group has proven themselves as vehement. Student 1 reply: This is because most of the cases the media does not play an unbiased role. As the media has the problem to b e biased and human right is not properly projected they are bound to create a misconception pertaining to this proble. Student 2 Reply: Yet, I think that this problem needs to be critically reviewed and addressed to a greater level so that a better world can be revived. Student 1reply: Agreed! A Reflective Insight on Hate Speech and Double Standard The European legal treatment of Islamophobic as well as homophobic speech does the illustration of the two horns of the impasse that the democratic states are facing to forbid hateful speech. From the perspective of U.S. First Amendment, the European approach to speech is having the involvement of Islam specifically, which is representing a worst-of-both-worlds standpoint, whereas regarding the extension of their approach in regard to racist hate speech, European legislators as well as judges have banned anti-Muslim as well as pro-terrorism speech (Khan 2015). Prosecuting the right-wing extremists to say or write matters that lack direct provocations towards violence are having certain probable negative aspects that have been reflected upon by other scholars. Such prosecutions might be having the propensity for turning the haters into victims as well as martyrs, and they might at times do the driving of hate institutions underground in ways that makes it very tough in monitoring them. The counter-balancing of these downsides are done by the significant symbolic message that are targeted by the full as well as equal polity members, who receive safety as well as status from the state. But, a negative aspect in this context is associated with the other vulnerable groups, which even though get targeted by hateful speech have not been banned, are still not full and equal members (Hasan 2015). Irrespective of the changes that occurred in the legislation such as the 2006 Racial and Religious Hatred Act in Britain, the years that followed Danish cartoons publication in 2005 did the witnessing of virtually no success in respect of appeals from Muslims towards national and global legal establishments for restricting the publication of the Prophets caricatures. Muslim governments as well as NGOs are continuously trying to do the persuasion of Western states for including Islam within the protective domain of their present laws regarding blasphemy or hate speech or creating a new legal aspect of religious insult or religious defamation. However, Danish prosecutors declined for inducting the editors or cartoonists at Fyllands-Posten in respect of speech that was associated with blasphemy or hate. Moreover, the Danish courts also did the rejection of a private complaint regarding defamation (Khiabany 2015). In fact, after the January 2015 terrorist attack on the offices of Charlie Hebdo as well as a Kosher grocery store in Paris, there occurred the juxtaposition of the French celebration regarding the right of the magazine in mocking the powerful as well as powerless in a similar way. In this context, it can be stated that the speech related prosecution of the French Islamists did the predation of both the Charlie Hebdo attacks as well as the 2014 anti-terrorism law. Hence, the signal sent by the legal responses states that the European society members are having the freedom for mocking Islam but not advocating radical Islamism (McGEE 2015). In the same manner, the Europeans are having the freedom for mocking Islam but not mocking minorities based on race. The Muslims in Europe have constantly raised their objection regarding a double standard. Human rights in many countries are complex and contentious. There may be a debate over the rights and responsibilities of citizens in a country. Countries have various laws pertaining to expressions of hate speeches against religions, races or other nations. However the matter faces different treatment in different country. For example, in Australia expression of hatred towards someone elses race, religion or caste is not serious an offence enough to be punishable by law. Even the Australian Human Rights Commission does not have the power to take an action against the agitator if no complaint is lodged. The victim is required to initiate the process by lodging a complaint the person. There are once again several extents to which these complaints go. While some complainants do not advance much further while there are cases which reach the court and cause much debate. Australia, though home to people of several origins does not deal with racist or hateful comments strictly. Less than 2 % complaints are tried or backed by court order and most of them are mediated by either removal of the hateful materials or seeking an apology (sbs.com.au 2017). The United Kingdom has stringent laws dealing with hatred speeches involving caste, race, religion, nationality and other individual aspect. The Public Order Act 1986 recognises comments condemning a person race, colour, nationality or ethnic origins. The person who threatens, abuses or expression racial hatred is liable with a maximum sentence of seven years, fine or both. The Criminal Justice and Public Order Act 1994 imposes a sentence of six, fine or both. However, all hateful speeches may not be dealt with strictly in the country. Dale McAlpine, a Christian preacher was arrested for preaching homosexuality a sin on April 20, 2010. However, the jury decided not be prosecute the person and the police paid him compensation for arresting him. This action or treatment of a person spreading hate speech clearly goes against the British laws enacted to protect the dignities of its population with diverse origins. The freedom of speech is guaranteed in France to all citizens TheLaw on the Freedom of the Press of 29 July 1881. The freedom to express does not empower a person to spread comments or speeches targeting other persons race, religion, ethnicity, physical deformity or any other attribute. It is both a civil and criminal office which attracts a year of imprisonment, a fine of 45000 or both. The Gayssot Act 1990 empowers a person to file a case if he considers articles in newspaper or any other print media hurts his sentiments. The Gayssot Act awards a person with a jail sentence for 5 years and 45000 for trying to demean the harm on Human rights inflicted by the Nazis during the World War II. For example, in 1974 a judge prohibited a poster of a film showing a half clad woman crucified to a cross which hurt the sentiments of the Christians. This showed that unlike Britain and Australia, the French authority is stricter when it comes to protection of human rights. Reference Bonotti, M., 2017.

Mule killers Essay Example

Mule killers Essay It is very clear that the narrators father is very childish; he simply doesnt understand that Eula doesnt like him, and that he will never marry her. He doesnt realize the seriousness of the girls pregnancy, it seems like he thinks its just a disease thatll disappear again. Also, he doesnt understand why his father cries and prays. First when he is an old man, he realizes why his father cried. In the end the father and son are together picking asparagus in what used to be the narrators mothers garden. She is now dead, and nothing has grown in the garden since she died. It is very clear: he must have married the boring girl; why else would they be in her garden? When the mother lived, the garden was filled with beautiful flowers and herbs, now it is a big wilderness. As said before the father was very childish at the age of eighteen. He was very immature and he didnt understand the cause of his actions. Of course he has become more experienced and mature through the following years, but first in the end he admits who his father really cried for that night.

The narrators father never gets what he wishes for; he must deal with the second best. Eula was taken away from him, and Orphan was taken away from him too, he had to die because of the technological progress. In the end he even lost his wife. Text 4, the poem To His Lost Lover actually describes the fathers life well. The poem is about a man who lost his love, and he never fulfilled his wishes with his love. We dont know if she died or if she left him, but in both cases it matches the fathers life: he never had Eula, but he did dream about them doing things together and getting married. As said before, he lost Orphan too, who he loved very much indeed, and then in the end he lost his wife. The story doesnt tell whether he learned to love the mother of his son, but he probably did. She was all he had in life, and as he grew older and more mature, he probably learned to appreciate her, and when he finally learned that, she died. So he has had several lost lovers through time. Another theme is the change from child to adult. Teenagers are no longer children, and not yet adults. They dont have the innocence of a child, and they dont have the experience of an adult. In the teenage years the innocence and experience meet, and the teenager creates his or her own identity. This is described very well in William Blakes poem The Ecchoing Green from 1789. The first two paragraphs describe the innocence of childhood. Children are playing on the green, the sun is rising, the merry bells ring, the birds sing laud and the old people are laughing it is all very idyllic.

Cloudstreet by Tim Winton.

Cloudstreet by Tim Winton. The values and attitudes endorsed by a novel can best be identified through an examination of its conclusion and this is evident in the novel Cloudstreet by Tim Winton. Through close analysis of its conclusion, it can be seen that the main values and attitudes within and towards various concepts such as family, place and reconciliation presented in Cloudstreet, as a whole, are endorsed quite comprehensively in the closure of the text. Using particular techniques of characterisation, theme and narrative structure, these values and attitudes are made evident in the exposition of the text, where the characters have other values, and throughout the development, where the characters go through a life changing process, leading up to the conclusion, of which the characters realise the importance of these concepts.The concept of family is evidently valued in the conclusion of Cloudstreet. The novel endorses the importance of family and how the unity of family members can be rewarding as well as comforting.My sister and her baby.While some of the characters value complex structures of living, such as Oriel's value of hard work, Cloudstreet highlights that these structures of living cannot replace the joys, love and security experienced within family life. This importance of family togetherness can be identified within the conclusion of the novel, where the Pickles and Lambs are having a picnic together 'by the river'. They are happy, dancing and 'dizzy with laughter', embraced with an abundant supply of food of which Winton describes expressively, "Out of the crates come hams, cold chickensa jar of anchovies and a vat of pickled onions."(pg 422). The atmosphere of the family picnic is rather blissful, "But here, here by the river, the beautiful, the beautiful, the river, the Lambs and the Pickleses are lighting up the morning like a dream" (pg 423),

Class Project - Coursework Example They were different fronts changing each other on this territory during three days. As fronts are boundaries between air masses with different temperature and can also differ with content, I thought interesting weather changes could happen there. I also checked a temperature changes and weather history at the other site (www.wunderground.com). As I said, on synoptic maps we can see different marks on chosen place during three chosen days. There is a mark L – Low, - Cyclone 28th of July 2014. Near L’s usually are strong winds, which can change weather and bring clouds and precipitation. Also there is a yellow front line. 29th of July 2014 we can see a different front – a blue one, - there. Also Cyclone had changed coordinately. Last day it was L – Low, this day it’s H – for High. Winds blow clockwise here. It’s anticyclone, so clouds should be gone and weather could be fine (Calvert, J. B). 30th of July anticyclone is moving East. Also yellow marks for fronts are back. So clearly, these three days had been not the most boring ones. 28th of July. Temperature wasn’t very stable. It was the highest about 6 AM – 83-84F and all morning it was pretty warm. Temperature was lowing ‘till noon and about 7 PM was 53-54F. So it’s 30F per day change. Dew point this day was more or less stable, though lowed to 37F about 6 AM (about that time, when temperature was the highest). In the evening it was stable – 56-57F, though temperature was the lowest. Looking at PH graph, we see that it changes a lot. Again with the highest temperature about 6 AM it was low – a little bit more, than 20% and in the evening – about 80% while temperature was the lowest. So I suppose it was raining in Steamboat Springs, because as we also knew from synoptic map, there was a cyclone that day. But RH jumped. Again, it was the lowest about 5 AM (30%) and had reached mark 80% in the evening. As we

Additionally, the water needs to be of lower temperatures, which are some of the ideal conditions for surfing. The 9.0 Japan earthquake of March 11, 2011 was indeed a surprise to many. Scientists, despite having predicted the earthquakes occurrence, never expected its large size. Additionally, the earthquake resulted in the death of approximately 18,000 people, even though warnings were issued especially in people’s cell phones. The earthquake also shifted the earth from its normal axis of rotation through the redistribution of mass. Question 2: Looking at the Ring of Fire, name 8 other countries, besides Japan, that are familiar with frequent earthquakes. Tell me about 1 of them that made headlines in the news within the past year. In the ring of fire, other countries familiar with frequent earthquakes besides Japan include Canada, United States, Costa Rica, Mexico, Bolivia, Chile, Guatemala, and Russia. One of the nations that has made headlines in the past year is Costa Rica, in which a powerful earthquake of a magnitude of up to7.6 shook the nation and a wide swath of Central America early in the morning in mid-2013, making substantive news headlines. Pacific Ring of Fire refers to an area with frequent occurrences of earthquakes and volcanic eruptions, contributed to by tectonic shifts in the earth’s plates. Because of such factors, the pacific ring of fire experiences an increased number of tsunamis considering the frequent movement of the earth’s plates. There exist three major types of tides, semidiurnal tides, mixed tides, and diurnal tides. Semidiurnal tides involve the existence of two high tides of equal heights and two low tides of equal heights. Mixed tides on the other side have two periods of high water and two periods of low water each day; however, the tidal heights are not equal.

Research paper on Armenia Essay Example | Topics and Well Written Essays - 1750 words

Research paper on Armenia - Essay Example In this paper, we will focus on the historical contexts of Armenia. With that, we mean that we will delve into the historical times of the country and what cultural attachments there are for us to see and understand from in the context of Armenia as a historical state. Whilst on the topic of research for this paper, we find that Armenia as a nation has never found things going easily for herself. There have been invasions, troubles, and battles all around which have marred the historical significance of the country nonetheless. Armenia since prehistoric times has been proposed as the Garden of Eden as it is surrounded by the Biblical mountains of the Ararat. The Armenian highlands are credited as being as first ones in the world to have any traces of human civilization. The capital of Armenia, Yerevan has founded in the year 782 BC and is a rich splendor when the talk rises up concerning the heritage of human civilizations. Orontid Dynasty is known as the first kingdom which was formed within Armenia and this had its fair share under the different dynasties that actually existed within the time until 428 AD. This kingdom became one of the most powerful ones between 95 and 66 BC. There were periods of independence which were enjoyed by Armenia during this time as well as autonomy was there for the rulers to enjoy during the dynasty. The dynasty thus can easily suggest to us the sort of aura Armenia had for its countrymen and women yet it failed to live up to the historians’ expectations in the matter that there were troubles looming all around.

Installation Of Windows 7 Computer Science Essay

Installation Of Windows 7 Computer Science Essay It choosing an operating system operating system, one must not only consider the features of his/her PC personal computer but also the compatibility of that PC with the OS of his/her choice. Windows 7 is compatible with almost all modern computers. The installation of Windows 7 is much easier and takes a shorter time than many other operating systems. Windows 7 comes in different editions including Enterprise, Ultimate, Professional and Home Premium. The installation process for all the versions is similar. However, one should choose the version that suits his/her interests to the fullest. The concept of the installation of Windows 7 can be broken down into steps that guide a user through the process. A clean installation will yield the best for any user who is interested in using Windows 7. Discussion Performing a clean installation should not be viewed as a hard task. Before a user starts installing the OS, he/she should first check the system requirements for windows 7 to ensure that the PCs hardware is compatible and is supported by the OS. Johnson (30) notes that it is necessary to download all the necessary drivers pertinent to Windows 7 from the manufacturers websites. The drivers can be saved in a USB drive or a CD-R before the installation begins. The operating system is usually available in a bootable DVD. For one to boot from the DVD, he/she needs to manage the boot sequence. The boot sequence appears under the BIOS set up. CD-ROM/DVD-ROM is the preferable boot device that a user should select. Johnson (33) also notes that there needs to be several other preparations that a user ought to make before installing the OS. In case a user does not want to lose the data already stored in the PC, he/she should back it up in a removable device to avoid overwriting the data accidentally and irrecoverably. He adds that an installation key is necessary (Johnson 34). Without the installation key, a user cannot install this operating system. The first step in the installation process involves inserting the Windows 7 DVD in the DVD tray then booting the machine. Since the boot sequence has already been selected, the user should click on Enter and continue with the process. Once this is done, the OS will start loading files. After the files are fully loaded, one needs to select the language of his/her choice and click on continue. In the next process, the user is allowed to install Windows 7 or repair the earlier version in case it was broken. As Andrews (114) asserts, it is essential for a user to read the license terms to avoid future complications that may arise if one realizes that the pack is not compatible with his/her machine. . Since this is a clean installation, a user should select Custom (Advanced) instead of Upgrade. Additionally, a user should select the drive in which to install the OS. According to Jimmy Westwood, an IT technician at Microsoft, it is essential to delete the earlier version of the OS before installing a new one to avoid excessive and unnecessary allocation of disk space during clean installation (Bott, 49). In case a PC has one hard drive, a user may choose to partition it by clicking on the Drive Options. Bott (51) notes that Windows 7 requires not less that 16GB free hard drive space. However, the operating system takes only 7GB of this space. After satisfactorily allocating the space, click on Next and continue with the process. During the installation process, the PC restarts several times. Eventually, after the installation process is completed, the user is supposed to provide the username and computer name before continuing. Andrews (115) adds that, for security purposes, a password is highly essential. The next step involves the activation of the operating system. Windows 7 activation is essential to avoid expiry of the OS. However, a user may choose to continue without entering the activation key, but the OS will run for a trial period of 30 days. Therefore, one must activate the OS within the 30 days, after which he cannot access his/her PC since the OS is expired. This indicates a notable difference between Windows 7 and Windows XP installation. In XP, a user cannot continue with the installation process without providing the activation key since XP does not have a trial mode. After successfully activating Windows 7, the pack is almost ready for use. One can choose to configure the updates, although Johnson (36) suggests that this should be done after the OS is fu lly installed and running successfully. The rest involves the setting of ones time zone and location. Home and work networks are highly recommended while configuring ones location. Public networks are not trustworthy in most cases. Comparably, the installation of Windows 7 is much easier that installation of Windows XP. It is also more user-friendly and streamlined than the latter versions. However, Windows 7 is associated with some restrictions such as portioning that are not there in Windows XP and Vista. Nonetheless, the procedure should take not more than an hour considering its simplicity. Additionally, the shift from Windows XP to Windows 7 is technically easy because of the in-place upgrade provided in this new version of Windows. The installation process of Windows 7 and Windows XP bear some similarities. In both operating systems, a user can opt for dual boot installation. This allows a user to operate his/her PC using two operating systems. However, the process needs care since one of the operating systems may delete the other (Bott 49-51). Furthermore, once installed, Windows 7 offers a multiplicity of advantages to its users compared to Windows XP. Windows 7 offers integrated and secure Virtual Private Network support through DirectAccess software. This implies that servers can be controlled effectively through the software. Second, the OS offers prior integration especially for the Windows 7 Enterprise and Ultimate Editions. This feature is absent in earlier versions. Third, the OS offers easier and less invasive user account control than windows XP (Andrews 121). Conclusion The shift from windows XP to Windows 7 requires a clean installation for a user to get the best benefits. The installation procedure requires several preparations such as the acquisition of drivers, activation key, as well as a check on the compatibility of the hardware with the OS. Although a user may function with the trial mode for 30 days, it is essential to provide the activation key to avoid the expiry of the OS. Conversely, XP installation requires the key and one cannot continue with the process without providing the key. For both XP and Windows 7, a user can do a dual boot installation to function with two operating systems. The installation process for Windows has been noted as easy as and more efficient than that of Windows XP.

Government and Politics - The Benefits of Federalism :: Exploratory Essays Research Papers

Government and Politics - The Benefits of Federalism In the early days of the United States, it was obvious to many that a system combining both federalism and representative democracy was needed. According to the textbook, â€Å"the people were too widely dispersed, and the country’s transportation and communication systems too primitive to be governed [solely] from a central location† (pg. 58). Although today both communication and transportation are highly advanced, America still maintains a federal system. The driving force behind that system is our increasingly expanding diversity. The United States ranks fourth in the world in size (www.stats.demon.nl/chart.area25.htm) and third in population (www.census.gov/ipc/www/idbrank.html). There are 213 languages spoken in America (www.sil.org/ethnologue/countries/USA.html) and probably just as many religions practiced. Federalism is the method by which this diverse population is better represented in the democracy of the United States. The national government makes many important decisions that impact our daily lives; however, there are some issues on which the opinion of the American public varies widely. In our federal system, the states are usually responsible for making policies that involve social, family, and moral/religious issues. This is one of the most important advantages of a federal system. The decentralization of the government allows the desires and needs of smaller groups of people to be acknowledged and fulfilled at the local level. Californians differ in many ways from residents of Arkansas who differ greatly from Alaskans. Variations in culture and lifestyle create needs for different political policies. A large, single, centralized government would be unable to make efficient social policies that were compatible with the convictions of a majority of America’s diverse groups. However, the national government still has enough power, through a system of checks and balances , to obliterate local policies that infringe upon the human rights of smaller factions. Federalism is not, of course, without disadvantages. To begin with, more levels of government equal a larger bureaucracy with many more people involved in the decision-making process. This provides more opportunities for corrupt government officials. Federalism also means that a complex tax system must exist so that each level of government receives funds from those in its jurisdiction in order to carry out laws and policies.

Quantitative Analysis by Spectrophotometric Methods Essay Example

Quantitative Analysis by Spectrophotometric Methods Essay Example Quantitative Analysis by Spectrophotometric Methods Paper Quantitative Analysis by Spectrophotometric Methods Paper Abstract In this experiment, the absorbance of KMnO4 was measured by spectrophotometric method to determine the molar concentration and the molar extinction coefficient of KMnO4. In part 1, in order to determine the maximum absorbance wavelength of KMnO4, we measured the absorbance of the sample solution which contains KMnO4 at the wavelengths between 330nm and 660nm, and plotted the ? and A points; the ? max was 530nm. In part 2, the effect of concentration on the absorbance was examined. We prepared five differently concentrated (but, same path length) solutions, and measured the absorbance of them at the ? ax(530nm) discovered in part 1; According to the results, higher concentrated solution had higher absorbance value. The extinction coefficient(? ) could be calculated from the results determined in part 2 and Beer’s Law; ? = 1. 7 x 103. In part 3, the absorbance of the KMnO4 solution of unknown concentration was measured, and using Beer’s law and dilution equation, the initial concentration of the unknown was determined; The concentration of the solution (unknown # : 15) was calculated to be 3. 3 x 10-3M. Introduction Our eyes are sensitive to light which lies in a very small region of the electromagnetic spectrum labeled visible light. This visible light corresponds to a wavelength range of 400 700 nanometers (nm) and a color range of violet through red. The human eye is not capable of seeing radiation with wavelengths outside the visible spectrum. The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. The white light is a mixture of the colors of the visible spectrum. Black is a total absence of light. Figure 5. 1 The electromagnetic spectrum. Although visible light acts as a wave in some respects, it also displays properties characteristic of particles. The particle-like properties of visible light are exhibited through small, energy-bearing entities known as photons. The energy of a photon is: E photon = hc / ? (1) where h = Plancks constant, 6. 626 x 10-34 J/s, c = speed of light, 3. 00 x 108 m/s, and ? = wavelength of light. Light is energy, and when energy is absorbed by a chemical it results in a change in energy levels of the chemical. Molecules normally exist in discrete energy levels. Vibrational energy levels exist because molecular bonds vibrate at specific frequencies. Electronic energy levels exist because electrons in molecules can be excited to discrete, higher energy orbitals. The energy (E) of light depends on its wavelength. Longer wavelengths (infrared) have less energy than shorter wavelengths (ultraviolet). A molecule will absorb energy (light) when the energy (or wavelength) exactly matches the energy difference between the two energy states of the molecule. In absorption, light - sunlight which is white light - strikes an object and part of the light may be absorbed by the object. The light we see coming from that object is the light which was not absorbed by the object. We see the not-absorbed light as the color of the object. If no light is absorbed, the object appears to be colorless. A spectrophotometer is employed to measure the amount of light that a sample absorbs. The instrument operates by passing a beam of light through a sample and measuring the intensity of light reaching a detector. The beam of light consists of a stream of photons. When a photon encounters a molecule, there is a chance the molecule will absorb the photon. This absorption reduces the number of photons in the beam of light, thereby reducing the intensity of the light beam. The ratio of transmitted light intensity(I) to the incident light intensity(I0) is the transmittance, T: T = I / I0 (2) The amount of light a sample absorbs is affected by its concentration. If there are samples of same substances but different concentrations, the amount of the absorbed light will be different. In higher concentrated solution, more absorbing molecules are present in the path of the light, and the chance the light strikes the molecules will increase. So, more light will be absorbed by the sample; less light will be transmitted. In contrast, in lower concentrated solution, less light will be absorbed, and more light will be transmitted. The concentration is represented by the symbol C and is typically measured in mole/L. Another factor that affects the amount of light a sample absorbs is the path length which is the length of sample that the light passes through. The path length is represented by the symbol l and is typically measured in centimeters. When the light travels through longer distance, it will strike more absorbing molecules, so more light will be absorbed, and less light will be transmitted. The relationship of two factors (path length concentration) can be combined to yield a general equation called Beers Law. log10T = A = ? lC (3) The quantity ? is the molar absorptivity; in older literature it is sometimes called the molar extinction coefficient. It is the measure of how strongly a substance absorbs light at a particular wavelength; a larger extinction coefficient means that substance absorbs more light. The units of ? are usually in M-1cm-1 or L mol-1cm-1. A is the absorbance of light by a sample, and in this experiment, it was measured directly by a spectrophotometer. Experimental 1. Maximum Absorbance Wavelength: For the first part of this experiment, we determined the wavelength at which a selected substance (KMnO4) would absorb best. We obtained 10ml of 0. 0040M KMnO4, and using a graduated 1. 0-ml pipette and a pipetting bulb, transferred 1. 00ml of it into a 25. 0-ml volumetric flask. We filled the flask half full with deionized water, and added 1. 0ml of 3. 0M H2SO4. After mixing the contents, we filled the flask completely with deionized water and mixed them again. After the sample solution was prepared, we calibrated a spectrophotometer using a blank solution; in this experiment, deionized water was used for the bla nk solution because H2SO4 is transparent in the visible region. For measuring the absorbance of KMnO4, first we selected a wavelength, and placed a cuvette containing blank solution, then replaced it with the other cuvette containing the prepared KMnO4 solution. The absorbance was measured at the wavelengths between 360nm and 660nm, and each time a new wavelength was selected, the spectrophotometer was recalibrated. After all the absorbance values were measured, we plotted the absorbance data versus the wavelength to determine ? max which was used for the remainder of the experiment. 2. Standard Absorbance Curve: For the second part of this experiment, we examined the effect of varying the concentration on the absorbance. Five differently concentrated KMnO4 solutions were prepared for this part. For each 25. 00ml sample, 1. 00ml, 0. 80ml, 0. 60ml, 0. 40ml, and 0. 0ml of 0. 0040M KMnO4, 1. 0ml of 3. 0M H2SO4, and deionized water were added. The concentration of each solution was calculated using the dilution equation, M1V1 = M2V2. After a sample was prepared, we set the spectrophotometer to the ? max discovered in first part, calibrated using the blank, and then examined the absorbance of the sample. After all the findings were examined, we m ade a plot of the absorbance versus concentration. The molar extinction coefficient could be calculated using the Beer’s Law and the measured results. The inside diameter of the cuvette (path length) was measured with calipers. 3. Concentration of an Unknown: In the last part, we determined the concentration of unknown solution using the results (the path length and the extinction coefficient) determined in the second part. We obtained a solution of KMnO4 of unknown concentration. We followed the same procedure as for the second part to dilute the unknown solution; added KMnO4, H2SO4, and deionized water to make 25. 00ml sample, and calibrated the instrument with the blank solution at the ? max, and then measured the absorbance. The concentration of the unknown before it was diluted could be determined using the dilution equation in a reverse way. Results Discussion 1. Maximum Absorbance Wavelength: In part 1, we determined the sample’s absorbance spectrum to find the wavelength (? max) at which KMnO4 absorbs best. The absorbance data measured in this part is shown in Table 1, and Figure 1 is the absorbance spectrum constructed by plotting A vs ?. Table 1: Data for Maximum Absorbance Wavelength Wavelength360380400420440460480500 Absorbance0. 1450. 0770. 0210. 0080. 0170. 0510. 1320. 253 Wavelength520540560580600620640660 Absorbance0. 3620. 3600. 2460. 1130. 0400. 0300. 0220. 018 Figure 1: Absorbance Spectrum of KMnO4 According to the graph, ? max of KMnO4 is about 530nm, and it means that at the wavelength 530nm, KMnO4 absorbs light best. 2. Standard Absorbance Curve: In part 2, we examined the effect of varying the concentration on the absorbance. We prepared five differently concentrated solutions (the higher concentrated solution appeared darker pink-violet), and using dilution equation, the concentrations were calculated. Figure 2: Color of permanganate in different concentrated solution The calculated concentration and the measured absorbance of each solution are summarized in Table 2. Table 2: Data for Standard Absorbance Curve Volume (ml)Concentration (M)Absorbance 1. 001. 6 x 10-40. 320 0. 801. 3 x 10-40. 252 0. 609. 6 x 10-50. 185 0. 406. 4 x 10-50. 122 0. 203. 2 x 10-50. 057 As shown in Table 2, when concentration decreased, the absorbance value also decreased. A plot of the absorbance verses concentration (Figure 4) resulted a straight line, and according to the equation (3), the Beer’s Law, we knew that the slope(2036. 563) of the line equals ? l. The path length(l) of the cuvette was measured to be 1. 18cm, and the extinction coefficient(? ) at 530nm was calculated to be 1. x 103; The molar extinction coefficient varies with the wavelength of light used in the measurement. Figure 3: A plot of Absorbance vs. Concentration 3. Concentration of an Unknown: The concentration of the unknown (#15) solution was calculated using Beer’s Law and dilution equation. Table 3 shows the data gathered. Table 3: Data and Calculation for Unknown KMnO4 Concentrat ion TrialVol. of KMnO4 AbsorbanceCon. after dilution (M)Con. before dilution (M) 11. 0 ml0. 2511. 3 x 10-43. 3 x 10-3 20. 8 ml0. 2121. 1 x 10-43. 4 x 10-3 30. 6 ml0. 1557. 7 x 10-43. 3 x 10-3 The mean concentration before dilution was calculated to 3. x 10-3M. In part 1, the maximum wavelength of KMnO4 was found as 530nm. When MnO4- is dissolved in water, it appears pink-violet, and as shown in color wheel below, it absorbs primarily yellow-green light. (The color a substance appears to be is directly across the wheel from the color of light that substance has absorbed. ) The range of the wavelength of green-yellow light is between 495nm ~ 590nm, so the maximum wavelength measured (530nm) is reasonable. Figure 4: The Color Wheel The absorbance spectrum shows how the absorbance of light depends upon the wavelength of the light. The spectrum itself is a plot of absorbance vs. wavelength and is characterized by the wavelength (? max) at which the absorbance is the greatest. The value of ? max is important for several reasons. This wavelength is characteristic of each compound and provides information on the electronic structure of the analyte. In order to obtain the highest sensitivity and to minimize deviations from Beers Law, analytical measurements are made using light with a wavelength of ? max. In part 2, we observed that the absorbance was lower in less concentrated solution. Before the experiment was done, we expected that in lower concentrated solution, because fewer number of absorbing molecules would exist, so less light would be absorbed; the expectation was correct. As I mentioned above, the solution appears pink-violet because permanganate absorbs primarily green-yellow light. The pink-violet color was darker in higher concentrated solution as in figure 2, and it can be explained that more green-yellow light was absorbed, so the violet color appeared darker. In part 3, we measured the absorbance of diluted unknown KMnO4 solution to determine the concentration of it. I got the sample of unknown number 15. We’d already known the value of the path length and the extinction coefficient, so we could calculate the concentration using the Beer’s Law. The solution was diluted to 25ml, so, in order to determine the initial concentration of the unknown, we used the dilution equation in a reverse way. The absorbance of the unknown was similar to the absorbance of the known sample, so I expected that the concentration would be similar; the known concentration was 0. 0040M, and the unknown concentration determined to be 0. 0033M.

Stomach Cancer Essays

Stomach Cancer Essays Stomach Cancer Essay Stomach Cancer Essay The human body is a complex system that has to be fully understood by us. It houses all the systems necessary for life. Each system works dependently with each other to sustain life. To acquire optimum body functioning, there should be a healthy relationship between the systems in our body.   Stomach, being part of the digestive system, holds a critical role in our body.   Like all the other organs in the human body, several alterations have been recorded that are considered threat to the human health. One of these is stomach cancer or otherwise known as gastric cancer. In order to understand what gastric is, it is imperative to determine first the anatomical and physiological structure of the stomach. This paper seeks to answer the following questions: 1.  Ã‚  Ã‚  Ã‚  Ã‚   What is a stomach? 2.  Ã‚  Ã‚  Ã‚  Ã‚   What is stomach cancer? 3.  Ã‚  Ã‚  Ã‚  Ã‚   What causes stomach cancer? 4.  Ã‚  Ã‚  Ã‚  Ã‚   Is stomach cancer caused by an individual’s genetic make up? 5.  Ã‚  Ã‚  Ã‚  Ã‚   Is stomach cancer caused by an individual’s environmental factors? 6.  Ã‚  Ã‚  Ã‚  Ã‚   How is stomach cancer diagnosed? 7.  Ã‚  Ã‚  Ã‚  Ã‚   What are the current treatments for stomach cancer? 8.  Ã‚  Ã‚  Ã‚  Ã‚   To which gender is stomach cancer most prevalent? 9.  Ã‚  Ã‚  Ã‚  Ã‚   To which race is stomach cancer most prevalent? The stomach is an expandable sack located mostly under the left lung, between the muscular diaphragm which pushes up the lung, and the coiled small intestine. The stomach is closed by important organs in the abdomen. To the right of the stomach is the liver, to its lower left is the spleen, and underneath it is the pancreas. The esophagus enters the stomach at the gastro-esophageal junction, while the small intestine exits it at the lowermost antrum. The front of the stomach rests on the abdominal wall, and lower parts of it also contact the upper left kidney and transverse colon. The important areas of the stomach itself are the greater curvature, the lesser curvature, the fundus and the cardia. The stomach has a delicate inner lining, made up of columnar epithelial cells, and acid secreting cells called parietal cells. The chemicals that protect this lining are called prostaglandins. The stomach has an impressive blood supply, mainly from the celiac artery which comes off of the main artery, the aorta. There is also venous drainage of blood to the spleen and liver. A secondary drainage system, called the lymph system, filters the blood in normally pea-sized lymph nodes. These are connected to lymphatics in other abdominal areas by lymph channels. Lymph nodes are full of white blood cells that help purify the blood serum; lymph nodes often enlarge when they detect spread of diseases. The point is that the stomachs rich blood supply and many drainage paths can act as conduits for spread of infections or cancers. The main purpose for the stomach is digestion of foods. Digestive process begins with the saliva in the mouth. In our diet, the stomach activates Vitamin B12, secretes hydrochloric acid to break down food, and churns the food into pulp. It can also directly absorb substances like alcohol and caffeine. The stomach is susceptible to an increase in the concentration of hydrochloric acid brought on by stress, certain foods, and the effects of tobacco smoke. While the stomach is normally protected against its own acid by an inner membrane, breakdown of this membrane leads to inflammation of the stomach, called gastritis.   An area that loses its membrane is also at risk to get an actual hole, called an ulcer. An ulcer may be shallow, and heal quickly, or it may be very deep and even perforate the outer stomach wall. Perforation is a surgical emergency. Fortunately, there are many medications now available which help reduce stomach acid concentration such as   Zantac, Pepcid and Tagame t, helping ulcers heal and preventing formation of new ones. Also, soothing protectants such as Carafate and even artificial prostaglandins can be given. These medications are often given preventively when the body is under great stress, such as after major surgery. While most stomach problems are minor ones, such as a mild virus or indigestion, occasionally serious disease strikes the stomach. The stomach is composed of various cells, which are intricately combined together into tissues which form the organ. These cells divide to produce new ones, and grow very rapidly during womb life, early childhood and puberty. In adulthood, new cells are produced only to replace those that die of old age, injury or disease. Normally, division of cells is under very tight control. This control is exerted by the genes inside each cell, which are housed in long clumps forming chromosomes, which are visible under a light microscope. The genes themselves are made up of DNA, the master genetic code material. If the genes are damaged, say by chemicals or radiation, the control over cell division may be lost in one particular cell. Ultimately, cancer is considered a disease of the DNA. Stomach cancer starts in a single lung cell. That cell starts dividing haphazardly, making millions and billions of copies of itself. It takes up the nourishment needed by other cells, depriving them so the can cer can continue to grow. Quickly growing cells can clump up to form a tumor. A tumor simply means a swelling; it can be caused by inflammation or infection. A benign tumor only grows in its local area it cannot spread and is not cancer. By contrast, a tumor which can spread to other body areas is called malignant and this is cancer. The process of cancer spread to other areas is called metastasis, so only malignant tumors such as cancer can metastasize. Theoretically, cancer can spread to any area of the body, and it often grows better in its area of spread than in its area of origin. It is this capacity for spread that makes cancer so dangerous. If not treated successfully, it ultimately kills by debility, anemia, infection, and compromise of normal body functions. The body is made up of many types of cells. Normally, cells grow, divide and die.  Sometimes, cells mutate and begin to grow and divide more quickly than normal cells.  Rather than dying, these abnormal cells clump together to form tumors. If these tumors are cancerous they can invade and kill your bodys healthy tissues. From these tumors, cancer cells can spread and form new tumors in other parts of the body. By contrast, benign tumors do not spread to other parts of the body. Stomach cancer, also called gastric cancer is the growth of cancer cells in the lining and wall of the stomach. There are 85% cases of gastric cancer which are   adenocarcinomas that occur in the lining of the stomach. Approximately 40% of cases develop in the lower part of the stomach (pylorus); 40% develop in the middle part (body); and 15% develop in the upper part (cardia). In about 10% of cases, cancer develops in more than one part of the organ. Stomach cancer can spread or metastasize to the esophagus or the small intestine, and can extend through the stomach wall to nearby lymph nodes and organs such as liver, pancreas, and colon. It also can metastasize to other parts of the body specifically the lungs, ovaries, bones. The American Cancer Society estimates that in 2006, about 22,280 new cases of gastric cancer will be diagnosed in the United States and that about 11,430 people will die of the disease. Most people diagnosed with stomach cancer are in their 60s and 70s. The majority of these people who are diagnosed with gastric cancer are more than the age of 65.   Stomach cancer is the second leading cause of cancer-related deaths. Carcinoma of the stomach is the most common form of gastric neoplasm and accounts for about 2.6% of all cancer deaths (Cancer Facts and Figures, 1991). Stomach cancer has decreased 5-fold in the U.S.A. over the past 50 years. It is more common in males, extremely rare in children, and the average patient is 55 years old. The cause of stomach cancer is unknown, but there are certain predisposing factors recognized. Genetic factors seem to be important, since gastric cancer is more common in persons with blood group A. Geographic of environmental factors appear to be important since gastric cancer is common in Japan, China, Chile and Iceland. The incidence rate in Japan is one of the highest in the world. There are studies that showed that Japanese immigrants to the United States have an incidence rate comparable to that of other Americans. Genetic or hereditary risk factors include hereditary nonpolyposis colon cancer (HNPCC) syndrome and Li-Fraumeni syndrome which are conditions that result in a predisposition to cancer. People with type A blood also have an increased risk for stomach cancer. Medical conditions that increase the risk for the disease include pernicious anemia which results from a vitamin B-12 deficiency, chronic inflammation of the stomach or otherwise known as atrophic gastritis and intestinal polyps. The most important environmental factors in the cause of gastric cancer are (1) salt added to food; (2) food additives such as nitrates, in pickled or salted foods such as bacon; and (3) food factors in water and vegetables such as Vitamin C. Dietary salt enhances the conversion of nitrates to carcinogenic nitrosamines in the stomach. Salt is also caustic to the stomach and can cause chronic atrophic gastritis. Finally, hypertonic salt solutions delay gastric emptying. Delayed emptying increases the time during which carcinogenic nitrosamines can exert their effects on the stomach mucosa. The metabolism of nitrates and nitrites is very complex. Nitrates interact with amino acids in the stomach to form nitrosamines. The conversion of those carcinogenic nitrosamines is enhanced at a low PH by iodides and thiocyanates. Nitrates are thought to be active only when converted to nitrites and to cause stomach cancer once atrophic gastritis has occurred. Stomach cancer usually begins in the glands of the stomach mucosa. Approximately, 50% of all gastric cancers develop in the prepyloric antrum. Atrophic gastritis and intestinal metaplasia are strongly linked to the development of gastric cancer. Insufficient acid secretion by the atrophic mucosa creates a relatively alkaline environment that permits bacteria to multiply and act on nitrates. The resulting increase in nitrosamines damages the DNA of mucosal cells further, promoting metaplasia and neoplasia. Duodenal reflux may also contribute to intestinal metaplasia. The reflux contains caustic bile salts to destroy the mucosal barrier that normally protects the stomach. There are three general forms of gastric carcinoma. Ulcerating carcinoma is the most common type and must be differentiated from a benign gastric ulcer. Polypoid carcinoma appears as a cauliflowerlike mass protruding into the lumen and may arise from an adenomatous polyp. Infiltrating carcinoma may penetrate the entire thickness of the stomach wall and is responsible for the inflexible â€Å"leather bottle stomach† or otherwise known as linitis plastica. The clinical manifestations of stomach cancer come in stages. The early stage is generally asymptomatic of produce vague symptoms such as loss of appetite, malaise and indigestion. Later manifestations of gastric cancer include unexplained weight loss, upper abdominal pain, vomiting, change in bowel habits and anemia caused by persistent occult bleeding. The prognosis is poor because symptoms do not occur until the tumor has penetrated the muscle layers of the stomach, spread to surrounding tissues and entered the draining lymph nodes and veins, causing distant metastases. Generally the first manifestations of carcinoma are caused by distant metastases. There are a range of choices by which stomach cancer is diagnosed. The choice of diagnostic tests depends on the clinical manifestation at the time of presentation. Most symptoms suggest a problem in the upper gastrointestinal tract. Direct endoscopic visualization and biopsy usually establish the diagnosis. Another definitive technique is microscopic examination of exfoliated cells obtained by lavage during endoscopy- an examination using a flexible viewing tube. Endoscopy is the best diagnostic procedure because it allows a doctor to view the stomach directly; to check for Helicobacter pylori-the bacterium that may play a role in stomach cancer; and to obtain tissue samples for examination under a microscope. The noncancerous stomach polyps are removed using endoscopy. If carcinoma is confined to the stomach, surgery is usually performed to try to cure it. Most or all of the stomach and nearby lymph nodes are removed. The prognosis is good if the cancer has not penetrated the stomach wall too deeply. In the United States, the results of surgery are often poor because most people have extensive cancer by the time a diagnosis is made. In Japan, where cancers are detected earlier by mass screening using endoscopy, the results of the surgery are better. If the carcinoma has spread beyond the stomach, the goal of treatment is to ease the symptoms and prolong life. Thus, chemotherapy and radiation therapy may relieve symptoms. Sometimes, surgery is used to relieve symptoms. For instance is when the passage of food is obstructed at the far end of the trunk, and out the right or left gastric artery. The bleeding site is identified by arteriography, after which a vasopressin infusion is started. Newer experimental methods include electrocuagulation, photocoagulation and application of polymers. At times when conservative methods fail, surgery may be the only method of treatment even though these patients are critically ill and poor surgical risks. The most effective surgical procedure is total gastrectomy, since these erosions are multiple or diffuse and tend to bleed again. The following data show the rate of incidence of cancers in the United States that have been evident not just for those who are whites, but also among the blacks, either female or male.   Please click this cancer.org/docroot/stt/stt_0.asp and attach them to the paper. I made it right like this coz it is difficult to paste the maps, graphs etc. to this order. From this site, you can download the maps and graphs which will show the incidence of gastric cancer not just in the US but worldwide. Indeed, there are several factors that predispose the onset of stomach cancer. Whether these factors are genetically based or have been caused by environmental factors, it is critical to be well-educated about stomach cancer. One could not directly conclude whether stomach cancer is caused by genetics or by the environment. In fact, studies have shown that all these factors can cause stomach cancer to an individual and may even worsen the condition, as the case there may be. Having enough knowledge as well as making the right treatment choices can make the difference of life or death. Understanding the causes and treatments of stomach cancer will help a person be conscious of his health. Through awareness, the whole population will get rid of the factors that might cause this cancer. By doing so, the incidence of stomach cancer will be lowered down and that good and sound health will already be acquired by the population, regardless of gender, race or socio-economic conditions.

Introduction to the research process Essay Example | Topics and Well Written Essays - 2000 words

Introduction to the research process - Essay Example These purposes give a clear notion about the hypotheses the study is built on, although no formulation can be found in the text. Firstly, the authors believe that both groups (diabetic patients and health practitioners) tend to demonstrate certain level of coincidence in perception of the issues that affect efficiency of the management of type 2 diabetes. Secondly, Pooley et al assume that the nature of the respondents' views coupled with the level of coincidence between the views of professionals may elucidate the major characteristics of a highly effective patient empowerment approach. The authors provide a good synthesis of relevant information on the previous studies thus linking potential findings of their study to a wider framework of theoretical knowledge on the management of chronic conditions similar to diabetes. They also identify gaps in the existing body of knowledge thus fully justifying the need for their own research being performed. Methodological framework employed by the authors for their study deserves particular attention. Specific nature of the formulated research purposes raised a set of strict requirements to be addressed within a certain methodological framework. It might be misleading to discuss appropriateness of the methodology used in the study without mapping the basic characteristics of qualitative and quantitative techniques utilised by the researchers. Discussion Quantitative methodology employs methods historically applied in the natural (physical) sciences. The primary task of quantitative research is to ensure validity and reliability of results (Dingwall et al, 1998). The concept of reliability as applied in quantitative research can be defined as: "The extent to which results are consistent over time and an accurate representation of the total population under study is referred to as reliability and if the results of a study can be reproduced under a similar methodology, then the research instrument is considered to be reliable" (Golafshani, 2003: 598). Quantitative research implies standardized questionnaires and methods of data analysis, specific position of the researcher whom is considered external to the research he carries out, replicability of the results regardless of the context, etc (Wainer & Braun, 1998). While reliability and validity are the most often cited strengths of the quantitative methodology, poor applicability of this methodology to studying a phenomenon difficult or impossible to quantify is considered a serious weakness. The main drawback that limits applicability of quantitative paradigm in health research is the so-called 'decontextualization': models built using data obtained through quantitative methods do not take into account certain variables that act in the real world context (Patton, 1987). Qualitative methodology represents a distinct research paradigm that ensures the researcher' immersion in the context of his study, makes him an active participant of the study. Qualitative framework utilizes a naturalistic approach seeking to understand phenomena in a specific context, such as "real world setting [where] the researcher does not attempt to manipulate

Individuals with Disabilities Education Act Essay

Individuals with Disabilities Education Act - Essay Example The phrase "free and appropriate" would come to be one of the first ideas school administrators and special education teachers would consider when planning and serving those students. The first component declared that all students, no matter what their disability, were entitled to a public education that had to be free of expense and suitable to each student's needs - or "free and appropriate." The second component created safeguards to prevent improper identification of children who were culturally or linguistically different from the student norm. Evaluations had to be administered in the child's native language by a skilled professional. They had to address specific areas (e.g., speech, language, math, behavioral), be made up of more than one procedures, fair to the students, and given by a multidisciplinary team with members representing all components of the students' education ("The Education For All Handicapped Children Act (PL 94-142) 1975"; "Public Law 94-142 (S.6); Nov. 29, 1975 Education for All Handicapped Children Act of 1975"). The third component involves the creation of an Individualized Education Plan (IEP) to meet their individual educational needs. An IEP team must meet annually and examine the plan for possible updates. The principle of Least Restrictive Environment forms the fourth component. It states that disabled children must be educated with non-disabled students to the greatest possible extent education ("The Education For All Handicapped Children Act (PL 94-142) 1975"; "Public Law 94-142 (S.6); Nov. 29, 1975 Education for All Handicapped Children Act of 1975"). The fifth component states that a system of due process and checks and balances will be used for disabled students and their families. Parents must give permission for testing and placement, may examine student records at any time, have an independent evaluation performed by an outside party, have a hearing, make appeals, and expect confidentiality ("The Education For All Handicapped Children Act (PL 94-142) 1975"; "Public Law 94-142 (S.6); Nov. 29, 1975 Education for All Handicapped Children Act of 1975"). The last component declares that parents have a right to be included in all phases of the placement, including assessment, placement, and IED development education ("The Education For All Handicapped Children Act (PL 94-142) 1975"; "Public Law 94-142 (S.6); Nov. 29, 1975 Education for All Handicapped Children Act of 1975"). Over the years, the law was reauthorized several times and experienced many important changes. PL 99-457, in 1986, expanded the scope of IDEA by adding provisions for the education of infants and toddlers (essentially from birth) with special learning needs. Its goals were to improve the development of infants and toddlers with disabilities, and to reduce the potential for developmental delay. It also wanted to reduce the chances of such a child being institutionalized. It sought to help families meet the special needs of those children, and tried to keep them out of special education, when possible. (Apling and Jones, 2002). In 1990, PL 101-476 gave the law its current IDEA moniker and ordered states to extend all the provisions of PL 94-142 to preschool-age children; public funding would facilitate these early intervention services. The expansion was based on the idea that falling cognitively behind

Happy Days Assignment Example | Topics and Well Written Essays - 250 words

Happy Days - Assignment Example Additionally, the improved economic conditions catapulted many Americans from low class to medium income earners. Most families could afford a car, and top of range products such as fridges, televisions among others. It is also worth noting that 50s marked an era of tremendous growth in the housing industry as well as transport infrastructure and networks. The increased number of affordable houses and high quality road networks made life easy for Americans. On a different note, entertainment became entrenched in people’s lives hence improving social life for Americans. Most significantly, Americans were enjoying high quality of life compared to many countries in the world. This made Americans feel at the epitome of the world. However, not everybody enjoyed the happy moments. An appreciable portion of Americans was already on their old age and had suffered the aftermath of World War II making it difficult for them to enjoy the 50s. Additionally, political critics and conservatists spent more time critiquing the government instead of taking advantage of the overwhelming opportunities present during that time. Left behind were the uneducated citizens, and African Americans who could not fit in the job market. Without a good source of livelihood, such groups could not enjoy the benefits of 1950 era. However, the 50s was by general means, good moment for

The five major ideas in reading are some of the basis of the curriculum and the instructions. They inspire the various assessments that to be used. Phonemic Awareness: It involves the ability to and be able to manipulate sounds in words. It also involves the ability to isolate letters and sounds and also to blend sound and segment sounds. Alphabetic Principle: This refers to the capability of associating sounds with letters and uses these sounds to form new words. Fluency with text: Is the effortless and the ability of the reader to read words in connected text automatically. Vocabulary: Being able to effectively understand and use words so as to acquire and convey meaning. Comprehension: This process involves the intentional communication that takes place between the reader and the text to be able to convey meaning. Literacy Centers Each day a child will be expected to participate in centers. This will allow the children to be able to explore various materials, try to reinforce concepts already taught and direct their own learning. The centers are likely to change weekly. They include: Word wall centre, Art centre, Listening centre, poetry centre, spelling centre and Reading centre. Writing, Spelling and Phonics The children will be given the courage to apply their knowledge of letter sounds as temporal spelling. After the child knowing how to say words slowly as well as listening to the sounds, this should help him record the message and think of himself as a writer. As the child progresses, he will be expected to move toward a more convectional spelling and therefore will be held increasingly accountable. Words and spelling of high frequency are taught when working with words block of time. In each week, there will be an introduction of word wall words which will be seen by the child always during the time of reading and therefore he will need to spell frequently while writing. To add on that, through these words, the child will be taught letter sounds and some spelling patterns of the words that are well known such as â€Å"at† so that they are able to spell words like â€Å"fat†, â€Å"sat†, â€Å"mat† and even â€Å"cat†. The goal is to enable the child recognize the spelling patterns and then consistently use them while writing. The writers’ workshops will consist of ample time for writing, mini lessons and during guided writing sessions, there will be sharing of time. Grammar will be taught to children including the use of punctuation marks. There will be the use of modern manuscript as a form of handwriting. There will be no extra time being spent on teaching formal handwriting, but rather there will be incorporation of the teaching of proper letter formation into some other daily lessons. Reading Curriculum The development of literacy will form the primary focus of the first grade year. There will be a well balanced literacy program which will include a wide range of language experiences which involve reading, writing, listening and speaking (American Association and School Administrators, 2006) Reading aloud to children This will be a guided reading where by the teacher will be required to read allowed for the children to pay extra attention to be able to hear what is being read.

Shared Reading This is also referred to as Independent reading. There are two forms of independent reading: †¢ Children read in group together †¢ Children read alone First, there will be grouping of children to enable them read as a group. In this they will be able to assist each other catch up. Those who are fast in mastering the words are likely to play important roles. After doing this the children will be allowed to read on their own (individually). This is the best time to determine whether a child has got something from the session.

The Existence of Evil :: Philosophy Religion Ethics Essays

The Existence of Evil Six years ago a little girl from my church approached me and asked why the devil existed, and why bad things happen. At the moment I was a little perplexed and did not know what to say. All that came to my mind was that humankind needed a scapegoat to blame for the occurrence of unfavorable incidents. Blaming adverse conditions on the devil is the easy and obvious way out of any situation. All one has to do is to say that the devil was the cause of the situation and wash his hands of the entire problem. At twelve years old, I thought that humanity used the devil as a way to elude responsibility and to ignore the consequences of its actions. It was not until last year that I realized the answer to the little girl's question about the existence of evil. In English class last year I read Arthur Miller's play The Crucible as required reading. According to my English teacher, one theme of The Crucible was that having evil in the world is necessary to balance out the goodness. If either entity overpowered the other, they would throw off the entire balance. Beside maintaining balance, evilness helps humanity to appreciate the goodness in the world. Without ugliness, a person cannot enjoy beauty. Without misfortune, a person cannot enjoy fortune. And without evilness, a person cannot enjoy goodness. No one could enjoy goodness in the world, because there would be nothing to compare with it. Concerning religion, if there was no devil in the world to make humanity miserable, then it would not look forward to heaven. There would be no difference between the two, so humankind would not have to question its actions because there would not be any consequences such as heaven or hell. Imagine a world where everything is perfect, and there is no suffering. Natural laws are bent at the hint of harm to humanity. If a plane carrying passengers starts to plummet, gravity ceases and the plane floats down to earth like a feather. Or if a gun is shot at a person, the bullet turns into a marshmallow so it will not harm anyone. In that world there is no pain nor suffering, just existence. The people do not have to adapt to their environment, because the environment adapts to them. I find this version of life frightening, because the people would take everything for granted.

Black People and African American Actors Essay

â€Å"We black men have a hard enough time in our own struggle for justice, and already have enough enemies as it is, to make the drastic mistake of attacking each other and adding more weight to an already unbearable load. † (Malcolm X) African American men through time have struggled for a power that is out of their reach because others hold the power. August Wilson’s Fences displays a Psychological/Psychoanalytic approach by illuminating the inherent injustice in America’s treatment of African American males and the ways in which this racism affects and invades the societal units – the family. The conventional husband-wife and father-son conflicts are subservient to the plays discussion of racism. Fences is a drama that focuses on the characteristics of black life in a small neighbor in 1957 and the strains of society of the Maxson family. The play shows how the main character struggles against his oppressive past and his present surroundings, and when he tries to regain the power in his life, he fails, and ends up bringing down other with him. The protagonist, Troy Maxson is a restless trash-collector and former baseball player for the Negro League. In the play, Fences, Troy’s past dictates the kind of man he is today. His father, an abusive unsuccessful sharecropper, has had a major impact on Troy. Troy states, â€Å"But I’ll say this for him†¦he felt a responsibility toward us. † (1310; all page references are to class text Literature an Introduction to Reading and Writing, 5th ed. ) This comment is the one good thing that Troy has to say about his father. Despite his father’s meanness, he did feel a sense of duty toward his family. After an incident with his father beating him unconscious, Troy left home at the age of fourteen (Wilson 1311). Leaving the oppressive rule of his father should have brought Troy a feeling of freedom, but Troy found the exact opposite. Troy found that there were no jobs or places for blacks to live so he began stealing to survive. He met a woman and got her pregnant with his first son. Lyons. The responsibility weighed on him because now he had two more mouths to feed (Wilson 1311). To take care of his family, he continued to steal which ended him jail for fifteen years and this is where he learned to play baseball. Troy Maxson was a great baseball player, at least according to his friend Bono. Although he played brilliantly for the â€Å"Negro Leagues†, by the time that blacks were allowed into the Major League Troy was too old. In Troy’s self-created illusion, he believes that he would have made it to the Major League if it were not for the color of his skin (Wilson 1292). Because he never earned the recognition or the money, which he felt he deserved, the discussion of professional sports will often send him into a tirade. In a discussion with Bono and Rose concerning Cory recruitment by a college football team, Troy states, â€Å"Jackie Robinson wasn’t nobody. I’m talking about if you could play ball then they ought to have let you play. Don’t care what color you were. † (1. 1. 78). Troy points out the blatant racism that kept him from a career in the major leagues. He was just as good, if not better, than many of the white players, and yet he did not get a shot. Troy, now fifty-three, has long retired from baseball; he makes a living for himself and his family as a garbage man, and nurses his well-earned bitterness. His life has been warped by white racism, and in turn, Troy is helpless to keep himself from warping his son’s life. Because of the racism, Troy has suffered in life and the tumultuous relationship with his father, Troy tries to control both is son’s lives. Troy has a low expectation of what black men can do with their lives, and is holding his sons back from obtaining successes that Troy could only dream about obtaining. Lyons is ambitious talented jazz musician. Lyons jazz playing appears to Troy as an unconventional and foolish occupation. In the beginning of Fences, Lyons comes to Troy to borrow ten dollars because he girlfriend Bonnie has a job working at the hospital. In Troy’s mind, Lyon is failing in his duty as a man by not taking care of his woman. Troy lectures Lyons, â€Å"I done learned my mistakes and learned to do what’s right it. You still trying to get something for nothing. Life don’t owe you nothing. You owe it to yourself. † (1. 1. 145). The quotation is an example of how Troy feels the black man will never amount to anything in the â€Å"white man’s world†. He also tries to control his son, Cory’s future because he see that he is going down the same road the Troy was on and was rejected from. Troy tells his wife Rose â€Å"The white man ain’t gonna let him get nowhere with the football. † (1. 1. 65). Through racial discrimination is still a huge problem in America during the 50s, things have gotten more equal, especially in the world of sports. Troy however is too stubborn and bitter to admit there has been some progress. Troy is now a fifty-three year old African American male who works for the sanitation department. Troy works to gain power as a man by changing his job situation. Troy goes to his boss, Mr. Rand and asks him â€Å"Why? Why you got white mens driving and the colored lifting? † (1. 1. 10). Troy sees this as oppression, though he knows that he has a job that is awarded to both white and black men, the racial line is till carefully drawn. He is determined to cross this line because he cannot handle any racial prejudices in his life. Troy continues to recount his fight with his boss to his long-time friend, Bono. Troy states, â€Å"You think only white fellows got sense enough to drive a truck. That ain’t no paper job! † (1. 1. 10). Troy feels that blacks are good enough to be drivers; he assumes that they would not be able to handle â€Å"paper† or office jobs. This is another example of how racism is so entrenched that black people are a little racist against themselves. Troy’s characters sought after this job in order to gain back some of the power in his life, even though he does not have a license to drive. He is finally able to prove to himself and the people around him that he is worthy and just as good as any other man, including white men. As a father, Troy feels obligated to provide the necessities of life, but he seems to think his duties end there. During a discussion between Cory and Troy, when Cory asked he father, â€Å"How come you never liked me? † Troy replies, â€Å"You live in my house†¦sleep your behind on my bedclothes†¦fill you belly up with my food†¦cause you my son. You my flesh and blood. Not cause I like you? Cause it’s my duty to take care you. † (1. 3. 107). It is clear the legacy of racism threatens to take another generation. However, he was unable to provide for his family alone and had to use the tragic injuries of his brother, Gabriel, a World War II veteran. Troy uses this money to pay for his house. He says, â€Å"If my brother didn’t have that metal plate in his head†¦I wouldn’t have a pot to piss in or a window to throw it out of. And I’m fifty-three years old. † (1. 2. 64). He feels weighed down by the guilt of using his brother’s destruction as a way to jumpstart his own life. He feels like the only reason he has anything is the fact that his brother life was ruined. Through he has a loving relationship with his wife Rose, he still strays and finds a woman with which he feels he can be a different man. He uses this affair as a way to escape from the responsibility of his life and the constant reminders of his shortcomings as a man. When trying to explain why he had the affair he tells Rose, â€Å"I can step out of this house and get away from the pressures and problems†¦be a different man. I ain’t got to wonder how I’m gonna pay the bills or get the roof fixed. I can just be a part of myself that I ain’t never been. † (2. 1. 98). His affairs results in a baby, and he needs Rose to help him, after his mistress, Alberta, died. Rose accepts the responsibility of raising this child, but she has cut off all emotion bonds with Troy. Rose tells him â€Å"I’ll take care of you baby for you†¦Ã¢â‚¬â„¢cause†¦ like you say†¦she’s innocent†¦and you can’t visit the sins of the father upon the child. From right now†¦this child got a mother. But you a womanless man. † (2. 3. 4). It is with this act that Troy loses more of his control and finds himself even more emasculated than before. Troy was unable to see that he did have control over one aspect of his life, yet he was too worried about proving his worth to others and to himself, that he proved his unworthiness to his own wife. Troy is a resentful victim of his life’s circumstances, a man who has become fenced in from happiness by the conviction that he was never paid what he was owed in any right: not from his father, not from his former baseball career, not from his employers, and not from his family. Troy tried to take back the power that was taken from him by demanding that his loved ones live practical, responsible lives while he has the freedom to have an affair, rebel against racist practices of his employers by protesting the limitation of black workers as lifters not drivers on the trash trucks. Troy refuses to see life in any presented to him but the way he perceives events in his own head. Eventually, Troy’s death leaves many negative attributes an inheritance for his family to sort out and accept. Fences I. INTRODUCTION (4-6 sentences) A. Quote B.
