Resistance: Rescue and Resistance in Nanjing. Facing History and Ourselves. Accessed December 01, 2018. https://www.facinghistory.org/nanjing-atrocities/atrocities/rescue-and-resistance-nanjing. Ã Ã Ã Ã Ã Ã Ã When the Japanese attacked Nanjing many people fled the country and continued to fight against them because they were not giving up yet. Others that stayed in the country still fought as well as helped the ones that were injured or sick. The ones who refused to flee were staying to help people in the refugee camps where they provided safety. Many of the people felt they needed to stay and help those who needed it. They didnt want the Japanese to win and take over so they had to do what they has to and resist against them. In the letters they talked about the Committee safe groups that were made. This source is good since it directly explains what each person had in mind and how they planned to resist. Some people within the country believed that them staying there would make things worse. The injured and sick were already going to die so they saw no point in staying and trying help when they would just sacrifice themselves. NICK B. WILLIAMS Jr. | Times Staff Writer. Cambodian Resistance Goes on Offensive : Despite Differences, 3 Factions Operate as More of a Guerrilla Force. Los Angeles Times. August 08, 1985. Accessed December 01, 2018. https://articles.latimes.com/1985-08-08/news/mn-3333_1_guerrilla-force. Ã Ã Ã Ã Ã Ã Ã The Cambodians resisted against the vietnamese by starting a movement and became almost like a Guerilla force. Since the Vietnamese drove them out of the camps they needed to step up. The Cambodians resistance movement was probably the most effective since quite a few Vietnamese soldiers were killed. In the Los angeles times it said In past years, the non-Communist factions operated close to their border bases. With all three factions now pressing to carry the fight to the interior, ?we are stepping on each others toes, Abdul Gaffar Peang-Meth, a spokesman for the Khmer Front, said recently (Los Angeles Times). Although the killing of some vietnamese may have been effective in showing they resist, both countries are just getting on each others nerve, therefore causing the unnecessary conflict that will continue. This is considered a good source because it was first written at that exact time so we as readers can get that full effect and know that the info rmation we are obtaining is reliable. This bias in this is many think the Cambodians shouldnt have resisted and said they started the conflict between them. If they just backed off and didnt force into it, they would be fine.But as for the Cambodians they knew that standing by wasnt an option and they needed to resist against them. Genocides we have studied: United States Holocaust Memorial Museum. Accessed December 02, 2018. https://www.ushmm.org/remember/the-holocaust-survivors-and-victims-resource-center/benjamin-and-vladka-meed-registry-of-holocaust-survivors/behind-every-name-a-story. Ã Ã Ã Ã Ã Ã Ã This source has a collection of stories written from Holocaust survivors themselves, explaining their experience and feelings. One of the victims that survived was Jakob, he wrote his story and talked about what happened during the whole thing. He wrote In the ghettos, typhus, malnutrition and other diseases ravaged the population, which caused many deaths, especially among the elderly and children. It was a miracle that I survived typhus (Ushmm- Jakob). This quote shows what he went through along with many others and emphasizes the true struggles that Jews went through. Having a survivor write about the holocaust makes it so real which helps to relate to the reader and appeal to their emotions. The Holocaust is considered a genocide because all Jews were forced out of their homes and put into concentration camps where they were tortured to their death. In the letter Jakob talks about how some people think they know what it was like to be in the holocaust but there are actually no words to describe it. This can cause bias between victims and other people because outsiders have absolutely no idea what it was like and for them to say they do is very disrespectful. Kifner, John. Armenian Genocide of 1915: An Overview. The New York Times. December 07, 2007. Accessed December 02, 2018. https://archive.nytimes.com/www.nytimes.com/ref/timestopics/topics_armeniangenocide.html?mcubz This is an article written by John kifner explaining an overview of the Armenian Genocide and what happened/ the causes. The Turks attacked the Armenians after WWI was over simply because the Armenians wanted to help Russia overthrow Turkey. Armenians were tortured and stripped of their pride when they were forced to go on marches naked in front of everyone.This is a good source since it was directly written from that point of time and shows the Armenians side of it instead of just the Turks intake. In this case,The turks decide what history is because they are the more powerful ones but as for this source it allows the Armenians to tell their story. The bias with this genocide is between the Turks and Armenians themselves. The Turks deny that a genocide took place because theyre afraid of the truth coming out. The Turks tried to claim that they didnt even carry out genocide and it was the Armenians that brought it on themselves. For this reason some believe the Armenians owe them an apology as they did it for a reason. Books: Matuszak, Nancy. History behind the Headlines: The Origins of Conflicts Worldwide. Farmington Hills, MI: Thomson/Gale, 2002. Ã Ã Ã Ã Ã Ã Ã This book talks about the torture the people of Nanjing went through as well as the war crimes being placed. This book is a good source because it shows what happened after the genocide was over and how the Japanese will be held accountable for their actions. They were finally held responsible in the end. Anyone that was on the Japanese side may now think other wise after reading this book. In the book it explains the truth about the genocide and exploits the Japanese making them look like the enemy they always have been. The only bias that could still be true is with the ones who still believe in the Japanese and think what they did was truly reasonable. Showalter, Dennis E. History in Dispute. Farmington Hills, MI: St. James Press/Gale Group/Thomson Learning, 2002. Ã Ã Ã Ã Ã Ã Ã This book tackles the main question of why the Holocaust is portrayed so differently from other genocides. In the book it said that the specific people were targeted,the Jews, and defined differently, making it different from others. This is a good source because it really digs deep into the holocaust and exactly why it is a more talked about genocide. Readers will be able to understand not only why the holocaust is considered a genocide but also other genocides and the reasons for it. Since the Holocaust is very well known, after this book youll know more about other genocides and get a feel for more terrible attacks, The holocaust isnt the only important one to note. The bias that this book takes on is the fact that other genocides are important to and need to get as much attention as the holocaust has. Theres a lot to learn and understand and victims of other attacks should be given the opportunity to speak freely of the events.

School Dress Codes: one of the most enforced school policies of all time for students of any age and gender.

Marc Handelman Part II: Research Methods Provide a brief overview of some of the research methods used by psychologists. Include strengths and weaknesses of each method discussed. Case studies) are in-depth investigations or studies of a single person, group, event or community. Case studies are widely used in psychology and amongst the best known ones being used in todays times. Case studies can provide great data and have high levels of authenticity of all the information collected also the participants show the most real reactions. (Interviews) in formal interviews are like a casual conversation. There are no specific questions and the participant is given the opportunity to talk about whatever topics he/she feels are important and ask them in their own way. formal interviews are like a job interview. They are set up in the same way in a organized manner in which participants can help determine what are their stress induced activities when put on the spot light. (Questionnaires) Questionnaires can be thought of as a kind of written interview. They can be carried out face to face, by telephone like when you are talking with a clerk representative over the phone The questions asked can be open, allowing flexibility in what people want to answer when being asked specific questions, or they can be more structured requiring short answers which are straight to the point and also they can be given a list of like multiple choice questions. ll of the questions must be carefully asked due to the fact that potentially biased, or offensive questions can be misunderstood.. Part III: Ethics in Research Describe two ethical issues related to research. Why is informed consent necessary for ethical research? Informed consent: this is required for the reason that participants must be informed and h ave had to acknowledge everything that is going to be done in the research and case studies and must have full understanding of what will go on through at all times. Confidentiality: this must be done for the reason that participants in some cases want full discretion of what goes on throughout the research and case studies. Failure to have all this documented could lead a dispute and possibly court actions by the participants. Part IV: The Brain and Mind Identify three major structures of the brain and their respective functions in the human body. The three main functioning areas of the brain are the cerebrum, cerebellum, and the medulla oblongata. The most largest and most functioning area is the cerebrum, which is responsible for the consciousness. The second largest portion of the brain is the cerebellum. It actually looks a lot like a butter fly so IÃ¢â¬â¢ve read and seen on pictures and works to coordinate muscle movement in order to have both smooth and graceful execution in the brain. The third and last area of the brain is the medulla oblongata which is close to the spinal cord. It contains receptors for heartbeat, breathing, blood pressure and reflex centers for vomiting, coughing, sneezing, and swallowing. How to cite Health Care, Papers

SmokingÃ Is a Silent Killer Essay SmokingÃ Is a Silent Killer Researchers claim that smoking is detrimental to memory . Prolonged heavy nicotine use has a negative effect on day-to-day memory, according to research. Researchers from five universities asked smokers and non-smokers to rate their long-term memory, for example remembering to send birthday cards. They found that smoking significantly impaired memory, with heavy smokers reporting the most errors. The survey was carried out by teams from Newcastle, Wales, North Umbria, Westminster and Teesside universities. The survey nvolved more than 700 people. Researcher Dr Tom Heffernan, of the human cognitive neuroscience unit at North Umbria University, also tested everyday memory including remembering where people had put things. The teams also took into consideration how much people smoked a heavy smoker was classed as having more than 15 cigarettes a week and alight smoker between one and four cigarettes a week. Dr Heffernan said: The result of the study reveal ed that smokers reported more errors in their long-term memory than non-smokers with an additional ifference between non-smokers and heavy smokers. There was also a significant detrimental effect of cigarette use on everyday memory function. For example a typical heavy smoker reported 22% more memory-related problems than a non smoker and around 12% more problems than those who smoked only relatively a small number of cigarettes It is concluded that chronic, heavy smoking is associated with impairments in everyday memory, although the precise nature of the deficits are as yet unknown.

Assonance. This technique is used to create an internal rhythm in sentences and phrases. It can be created with a repetition of the vowel sounds. Many writers use assonance to attract readers' attention. It helps to set the mood of reading.Ã Example of assonance - read the famous poem from Dylan Thomas sets the mood for readers: "Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, rage against the dying of the light.Ã Grave men, near death, who see with blinding sight Blind eyes could blaze like meteors and be gay, Rage, rage against the dying of the light."Ã Imagery. It is a language technique used by writers to draw an impressive and bright image in the minds of their audience. Example of imagery - read William Shakespeare's poem "Romeo and Juliet" where the author uses imagery of darkness and light: Ã¢â¬Å"O, she doth teach the torches to burn bright! It seems she hangs upon the cheek of night Like a rich jewel in an EthiopeÃ¢â¬â¢s ear Ã¢â¬ ¦Ã¢â¬ Imperative. Writers use this language technique when they need to create a commanding tone in their texts. Usually, imperatives are used in books for heroes to give orders, instructions, or requests. Example of imperative - read the following sentences: Do not eat anything after 6 pm! (instruction or order) Feel free to call me tomorrow (invitation) Stop saying this way! (order) Read the article to the end fast! (instruction or order) Idioms. These are phrases used by authors to make your writing more impressive for the audience. Read the most bright idioms below. Example of idioms in sentences: She was going to call it a night (she was going to bed) Last year, I missed my boat in college (I missed my opportunity) He said yesterday he missed a game because he felt under the weather (he was sick) I go to parties with friends once in a blue moon (I go partying very rare) She's sure that writing isn't her cup of tea (not a thing she can do successfully) Neologism. These are old phrases used by people very rare. It was invented by Shakespeare. We can find a lot of neologisms in his famous poems. Examples of neologism - read a sentence from Ã¢â¬Å"The Taming of the ShrewÃ¢â¬ : Ã¢â¬Å"Pardon, old father, my mistaking eyes, That have been so bedazzled with the sun That everything I look on seemeth green.Ã¢â¬ Shakespeare invented the word "bedazzled" to describe rhinestone-embellished clothing. You may read a lot of other neologisms in his poems. Onomatopoeia. It means to copy sounds of a thing. It is used by authors in descriptive writings to make them more interesting and impressive.Ã Example of onomatopoeia - it is used by Edgar Allan Poe in his poem "The Bells": Ã¢â¬Å"How they clang, and clash, and roar! What a horror they outpour On the bosom of the palpitating air! Yet the ear it fully knows, By the twanging And the clanging, How the danger ebbs and flows; Yet the ear distinctly tells, In the jangling And the wrangling, How the danger sinks and swells, - By the sinking or the swelling in the anger of the bells, Of the bells, Of the bells, bells, bells, bells - In the clamor and the clangor of the bells!Ã¢â¬ Ã Personification. Authors use personification to add non-human objects feelings and things from a human. This helps to turn the attention of the audience. Personification is used by many famous writers to make their stories more impressive.Ã Ã Ã Examples of personification - the poem by William Wordsworth "I Wandered Lonely as a Cloud":Ã Ã¢â¬Å"I wandered lonely as a cloud That floats on high o'er vales and hills, When all at once I saw a crowd, A host of golden daffodils; Beside the lake, beneath the trees, Fluttering and dancing in the breeze. Continuous as the stars that shine And twinkle on the milky way, They stretched in never-ending line Along the margin of a bay: Ten thousand saw I at a glance, Tossing their heads in sprightly dance.Ã¢â¬ Ã In this poem, the author brings the beauty of nature to real life. He personalised daffodils as dancing people and describes himself as a cloud that enjoys the show.

The Element Nitrogen - Research Paper Example Nitrogen is the most abundant gaseous component of earthÃ¢â¬â¢s atmosphere constituting 78% by volume.It is colorless, odorless and commonly inert gas.Nitrogen is a gas at room temperature with density of 0.001165 grams /cc. Solid nitrogen lets at 63.35 K and has a boiling point of 77.35 K. It has a relatively low heat of fusion and heat of vaporization of 51.48 J /g and 2.7928 J /mole respectively. Solid nitrogen has specific heat close to water at 1.040 J / g 0 C. Nitrogen has two stable naturally occurring isotopes, 14N and 15N. The predominant isotope being 14N has 99.636% natural abundance. Other isotopes are also noted but are short lived and decay rapidly. Triple bonding in diatomic nitrogen N2 is one of the strongest. Nitrogen has electronegativity of 3.04 and has 5 valence electrons in its outer shell; therefore, nitrogen is commonly trivalent in most compounds. Nitrogen is also non-flammable, therefore, is not combustible. It also has considerably high first ionization an d second ionization energy. Compounds of Nitrogen Nitrogen is non-metallic element. It commonly forms oxide in its different oxidation state. Nitrous oxide (N2O), nitric oxide (NO), and nitrogen dioxide (NO2) are the most common oxides formed by nitrogen. It also forms dinitrogen tetroxide (N2O4), and dinitrogen pentoxide (N2O5) using its higher oxidation state.Nitrogen also forms hydride as ammonia (NH3). Nitrogen combines with Fluorine to form various fluorides like Nitrogen trifluoride (NF3), Dinitrogen tetrafluoride (N2F4), cis-difluorodiazine (N2F2) and trans-difluorodiazine (N2F2). Nitrogen chloride and Nitrogen iodide can also be formed; NCl3and NI3. Ammonia (NH3) Ammonia is a colorless gas with characteristic pungent odor. It has density of 0.86Ã kg/m3. It is soluble in water to form basic hydroxide NH4OH. Solubility is increased at lower temperatures. Ammonia has trace concentration in the atmosphere as result of decaying matter. Ammonia and ammonium salts are present in rainwater and some areas where volcanic activity is noted. Ammonia is also present in soil and seawater. It is also found in Pluto, Jupiter and Uranium. The ancient Greek, European alchemists and the romans have historical writings about nitrogen. In 1774,Joseph Priestley successfully isolated gaseous ammonia and he called it alkaline air. Nitric acid (HNO3) Nitric acid is a strong acid commonly called aqua fortis and spirit of nitre. It is also a common oxidizing agent in organic and inorganic chemistry. Anhydrous nitric acid has density of 1.512 g/cm3, melting point of -420C and boils at 830C. Nitric acid partially decomposes to nitrogen dioxide (N2O) at room temperature. Nitric acid has been known since antiquity and is commonly used in alchemy. Nitrogen dioxide (NO2) Nitrogen dioxide is a reddish gas at room temperature. It is primarily an intermediate in the synthesis of nitric acid and a major air pollutant. It has density of 2.62 g cm-3and boils at 21Ã Ã °C. Nitric oxide ( NO) Also called nitorgen monoxide. It is a free radical and is unstable in normal conditions. It is a a byproduct of combustion of fuel oils and automobile engines. Nitric oxide is colorless and has denisty of 1.3402 g dm?3, melts at ?164Ã Ã °C, and boils at ?152Ã Ã °C. Solubility in water is 74 cm3 dm?3. Dinitrogen tetroxide (N2O4) Also called nitrogen peroxide. It is commonly found in equlibrium with NO2. It is known for its oxidizing power and corrosive properies. It is colorless gas with
