The Artificial Model Of Natural Selection Essay - 1866 Words

The Artificial Model of Natural Selection Since Charles Darwin raised the concept of natural selection, all generations have been enlightened with the idea of the â€Å"preservation of favorable variations and the rejection of injurious variations [†¦] useful in some ways to each being in the great and complex battle of life.† (Darwin, 1). However, only the most recent generations have heard about something called genetic modification that in some cases we don’t understand, but whose effects have been increased in our daily life. The innumerable advances that science had reached in genetic aspects, made people think that there aren’t insurmountable limits to humans. At the same time it causes questions about the dangers they may offer in an increasingly, curious society. In general terms, Genetic manipulation refers to â€Å"any of a variety sophisticated techniques for the creation of recombinant DNA and, in many cases, its subsequent introduction into living cells.† (Das 1). It implies a fusion between the natural composition of pure matter and the implanted characteristics as a consequence of that which human beings consider appropriate to improve the kind. Thus, through genetic management, human beings are trying to recreate a process of natural selection in which favorable conditions are preferred in the relationship of individuals with their environment, and allowing those conditions be incorporated over time.

Gender Identity And Gender Oppression - 1839 Words

Gender Identity and Gender Oppression has many opinions that have varied throughout the years. The awkwardness of seeing gay or lesbian characters in movies or tv shows have been decreasing throughout the years, or has it? Seeing movies display different genders than just male and female has introduced a diverse reaction from many people. Despite the setting of the book being in this dystopian futuristic world, gender identity and gender equality is subliminally present and plays a key role in the book. Gender Identity is restricted to just straight male and females in both schools and a group called Sixers, who wishes to gain power. In addition, gender oppression can be seen through influential characters. Orphaned at a young age, Wade†¦show more content†¦The food vouchers are taken away by Aunt alice, to show Wade that she is a fierce women and not a common one. Aunt Alice is doing everything necessary in order to survive, just as Wade’s father was while raiding th e store, which led to his mistaken death. Wade can be described as superior, he is a strong independent man while his aunt is a drug addict who survives through her greediness. Gender oppression is shown through the first chapter of the book Ready Player One by Ernest Cline. The author tries to depict his mother as a good mother, but one with a bad habit to lead Wade to success. On the other hand, Cline seems to describe his Aunt as a woman with no future, without bringing down Wade. However these people in Wade’s life lead him to become an independent and resourceful man. Transitioning from Wade’s personal life to his school and social life, Cline imposes restrictions on gender identity. Apart from gaming in OASIS, Wade is just a high school senior, who attends online school as well. Wade explains his school’s daily life and describes how â€Å"the school strictly enforced dress code required that all student avatars be human, and of the same gender and age as the student. No giant two-headed hermaphrodite demon unicorn avatars were allowed. Not on school grounds, anyway† (Cline , 2011, 28).

Bible Influences Essay Example For Students

Bible Influences Essay ZOROASTRIANISM, JUDAISM, ANDCHRISTIANITYZoroastrianism, Judaism, and Christianity share so many features that it seems that there must be a connection between them. There is a great deal of Zoroastrian influence in both Judaism and Christianity. In 586 BCE, the forces of the Babylonian Empire conquered the Jews, destroying their Temple and carrying off a proportion of the Jewish population into exile. It was during the end of the Exile, among the Jews now living in the Persian Empire, that the firstsignificant contact was made between the Jewish and Iranian cultures. And it is evident in the Bible that Jewish thinking changed after the Exile. During the Exile, Jews had to change not only how they worshipped, since they no longer had their temple or the animal sacrifices which had been at the center of their faith, but also how they thought about God. The Jewish concept of God as their tribal protector, who would save them from being conquered or exiled, had to undergo revision. Both factors are present, inspiring the changes in post-exilic Judaism: not only the Jews thinking new thoughts about God and humanity, but also contact with the Zoroastrian religion of the Persian Empire. Most of Zoroastrianism, known and practiced among the people, existed in oral tradition: through word of mouth, not by the study of written scriptures. This oral tradition included stories about God, the Creation, the ethical and cosmic conflict of Good and Evil, the divine Judgment and the end of the world. The tradition would also include the well-known Zoroastrian symbolism of fire, light and darkness, as well as stories and prayers about the yazatas or intermediate spiritual beings and the Prophet Zarathushtra. These are all elements of what might be called classic Zoroastrianism. This is how the Jews encountered Zoroastrianism in private dialogues and political and civic experience, rather than in formal religious studies. And as the Jewish religion was re-made after the catastrophe of the Exile, these Zoroastrian teachings began to filter into the Jewish religious culture. The monotheists of Zarathushtra were able to incorporate the veneration of subordinate divinities into their worship, as long as these subordinates were recognized as creations of the One God and not gods in their own right. The Jews would recognize angels as semi-divine intermediaries, but would not go so far as the Zoroastrians in honoring those intermediaries with hymns of praise such as the Yashts. One of the most important differences between Jewish monotheism and Zoroastrian monotheism is that Jews recognize the one God as the source of both good and evil, light and darkness, while Zoroastrians, during all the phases of their long theological history, think of God only as the source of Good, with Evil as a separate principle. There is a famous passage in Second Isaiah, composed during or after the Exile, which is sometimes cited as a Jewish rebuke to the Zoroastrian idea of a dualistic God: I form the light, and create darkness: I make peace, and create evil: I the Lord do all these things. (Isaiah 45:7) This passage, which is a major source for Jewish speculation on the source of good and evil in the world, denies the Zoroastrian idea of a God who is the source only of good and favorable things. The philosophical minds of the two cultures may indeed have recognized each other as fellow monotheists, but this central Jewish doctrine is one which was not learned from the Zoroastrians. It grew from the original monotheistic revelation attributed to Moses, just as Zoroastrian monotheism grew from the revelation of Zarathushtra. These were two parallel journeys towards understanding of one God. There are other developments, however, in the Jewish faith which are much more easily connected with Zoroastrian ideas. Human Rights Violations Essay This view of dualism is a symbolic transformation, and an expansion, of the more psychologically based teaching of Zarathushtra that good and evil are ethical choices and states of mind. Both cosmic and ethical dualism coexist in Zoroastrian thought throughout the long history of the faith; their history is not one of a pristine idea of ethical dualism which is supplanted or corrupted by the idea of cosmic dualism. And reflections of both types of dualism are found in Jewish thinking. The Biblical book of Deuteronomy, like the other early books of the Old Testament, was re-edited and possibly even re-written during and after the Exile. An important passage in Deuteronomy 30:15 shows a Jewish version of ethical dualism: See, today I set before you life and prosperity, death and disaster. If you obey the commandments of YHVH your God that I enjoin on you today, if you love YHVH your God and follow His ways, if you keep His commandments, His laws, His customs, you will live and increase, and YHVH your God will bless you in the land which you are entering to make your own. But if your heart strays, if you refuse to listen, if you let yourself be drawn into worshipping other gods and serving them, I tell you today, you will most certainly perish.. ..I set before you life or death, blessing or curse. Choose life, then, so that you and your descendants may live. (Deuteronomy 31:15-19, Jewish Bible Translation) But despite these Jewish reflections of ethical dualism, it is the doctrine of cosmic dualism, with its mythological and symbolic content, that most influenced the later Jewish thinkers. Even before the Exile, under the threat of destruction by foreign empires, Jewish prophets were moving toward a vision of not only political, but cosmic war and catastrophe. This type of prophecy, after the Exile, evolved into apocalyptic, which comes from the Greek word apokalypsis which means revelation. This is a form of religious storytelling, poetry, and preaching which uses a high level of mythological symbolism to describe not only a cosmic battle between the forces of Good and Evil, but also a schedule for the coming End of Time. It is very evident to see that even though the original text of the Gathas was most probably inaccessible to the Jews, the teachings of Zarathushtra were part of the religious culture of the Persian people among whom many Jews lived. Zoroastrianism, from the beginning, has taught that time and Gods creation has a beginning, a middle, and an end-time in which all souls will be judged. This is the basis of what the Christian belief is based upon and it is easy to draw the conclusion that Zoroastrianism had a great influence on Christianity and on the Bible. Religion

Margaret Sanger Essays - Planned Parenthood, Socialist Feminists

Margaret Sanger The early twentieth century was a turning point in American history-especially in regards to the acquisition of womens rights. While the era was considered to be prosperous and later thought to be a happy-go-lucky time, in actuality, it was a time of grave social conflict and human suffering (Parish, 110). Among those who endured much suffering were women. As Margaret Sanger found out, women, especially those who were poor, had no choice regarding pregnancy. The only way not to get pregnant was by not having sex- a choice that was almost always the husbands. This was even more true in the case of lower-class men for whom, sex was the poor mans only luxury (Douglas, 31). As a nurse who assisted in delivering babies, Margaret Sanger was very aware of how unwanted pregnancies affected lives. She witnessed the affects of self-induced abortions, the transferring of diseases from mother to child, and the deaths of mothers and children due to poor health conditions. Feeling strongly about t he problem unwanted pregnancies, Sanger devoted her life to acquiring the right for women to prevent pregnancies through the use of contraceptives. After years of dedication and hard work, Margaret Sanger not only accomplished what she had hoped for-making people understand the importance and necessity of birth control, but also accomplishes something greater by extending womens rights as well. In a society where it was considered inappropriate for girls to know about their anatomy and its functions, let alone talk and read about it, Margaret Sanger realized that she must create literature that informed girls about their bodies. She produced a pamphlet titled What Every Girl Should Know. In it, she discussed subjects like physical growth, mental development, puberty, menstruation, sexual impulses, reproduction, hygiene of pregnancy, and various venereal diseases (Sanger-Girl, 1). While her book was considered obscene, lewd and lascivious material (Gray, 43), Sanger was convinced that education about these topics were necessary. Through the publishing of What Every girl Should Know, Margaret Sanger demonstrated to common women, to her adversaries, and to the government that women deserve the right to learn about and understand their bodies. In addition to What Every Girl Should Know, Sanger created other propaganda, which informed women that they deserved the right to prevent births. The purpose of her first publication of this type, a magazine called The Woman Rebel, was to inspire women to demand rights. She wanted to stimulate working women to think for themselves and to build up a conscience, fighting character (Douglas, 50). In each issue of the Rebel, she discussed topics such as child labor, women and children in industry, health and cultural opportunities. She believed that women must determine her own maternity-This was the most precious freedom (Douglas, 50). Following The Woman Rebel, Sanger wrote a pamphlet called Family Limitations. In this pamphlet, Sanger discussed such topics as the use of condoms, the importance of douches, and the practice of coitus interrupts or withdrawal (Whitelaw-Every, 50). For this informational writing, Sanger called a heinous criminal who sought to turn every home into a brothel and it was denounced as indecent, immoral and a menace to society (Douglas, 85). By writing these works of propaganda, Sanger was trying to inform women that there were ways of preventing births. She wanted to lower the birth rate for several reasons. Doing so could improve the quality and health of their lives. Lower birth rates could also prevent the transfer of disease to their children and would not require their young children to work in factories in order to earn money (Whitelaw-Every, 54). Sanger advocated contraceptive devices and practices saying, Birth Control will make parenthood a voluntary function instead of an accident as it is today. When motherhood and children are free, we then can go hand in hand toward the emancipation of the human race (Sanger-Fight, 40). Another one of Margaret Sangers contributions to womens rights was her demand that women and men have equal treatment and conditions. This demand was brought on by the knowledge that men and women did not have equal access to condoms. Sanger knew that they were being used in various other countries as methods of birth control and that they were available

Research Paper Research Paper Matt McMahon Ms. Cooley Writing for College 16 December 2010 The Life of a New York City Fireman Every young boy has a specific person who he feels is his hero. Many of these heroes are seen on TV or in comic books. At a young age, these characters are referred to as superheroes. As these kids grow older, their views of idols change into professional sports players like Derek Jeter, Lebron James or Sidney Crosby. Once kids hit a certain age they don’t believe in the superheroes, they just have heroes from movies and sports. The funny thing is superheroes do exist and always have. Just because they cant fly and pick up buildings doesn’t mean they are any less heroic than the ones who can in comic books. When someone is in danger or in any type of life threatening situation, they depend on police officers and firefighters to be there for their safety. The system works much like how it did on cartoons or in comic books for that matter. When someone is in distress t hey call 911 who gets the information and refers it to a local fire departments dispatch. The dispatch then sends the call out to the fireman who race to report to the scene as fast as they can. Although being a firefighter is not as easy as it looks or sounds. Being a New York City firefighter is very different from any other job in the world. People go to their normal job about five days a week for about an eight hour shift. Being a firefighter isn't any normal job. The shifts research paper research paper Coming to a division three college as a student athlete was a difficult choice. This was mainly because I knew that in division three there were no athletic scholarships given, unlike division one and two. This made college more expensive for me, and definitely weighed in on my decision on what college to attend. Many people will argue that athletics are not an important part of a child and students career for many reasons. Most people who choose this viewpoint believe that it distracts the student from their academics, therefore damaging their future. The people who believe this agree that students should be studying instead of practicing their sport or playing in events. Therefore, why should athletic scholarships be given out? This would encourage students to practice even harder and longer to be able to achieve a talent good enough to be rewarded with a scholarship. Another reason people might be against athletic scholarships is because it would save the college money by not giving students free tuition. If the college did not give out athletic scholarships, they could save hundreds of thousands of dollars a year. This money could go to things such as academic tuition, building funds, or previous debts owned by the school. Although both of these arguments are valid, I believe there are strong counterarguments to each one. What many people don’t understand is that athletics encourage more than just physical toughness. I have learned that athletics have taught me much more than that; they have taught me perseverance, how to be supportive, and that hard work pays off. Also, student athletes are well rounded and have knowledge of time management. Student athletes are forced work hard in their academics in order to stay on the team. If you receive under a two point five GPA, you are ineligible to play for the team. This results in student athletes having some of the highest GPAs in colleges.

I can’t persuade one to change his/her opinion on the interest of his/her author. I can however provide details on how mine is a work of art. Richard Rodriguez, a man with no shame, splendid powers of deduction, and innovative writing. My reasoning shall be revealed in due time. Rodriguez has really enthused my writing. He has given me a more creative, and more, in-depth kind of thinking in my writing. His race and his sexuality are just assets to the man with the ink. What do I mean? I mean that others could be prejudice to either his ethnicity or homosexuality. Revealing one’s identity of sexuality is crucial in a career where people throughout the world criticize it. A good example of this is, Adam Lambert. A star who was contesting in and was supposedly going to win the hit show American Idol until he revealed his sexuality. Some say he was go ing to win and others say that has nothing to do with it. Now, I deem myself as a respectful and understanding guy. Therefore, I don’t judge the man himself (why would I be writing about him if I was), I judge his work. Some of the works I will be critiquing are a few essays, Cowboys and Indians, which is one of his more recent works, Se Habla Espanol, Zero Times One and a chapter out of his most famous work, Hunger of Memory. I’ve specifically chosen articles that are spread out through his career. Even though these four articles are spread through a decade of time, it is still noteworthy to evaluate to his progression in writing. Each of these writings are different, but cover the same idea. Rodriguez is Spanish (the Mexican descent) and he is a homosexual. Is that all there is to know though? Of course it is! What else could there be to know about an author? Sarcasm, that is what modern terminology defines as being ignorant, or hilarious, or both. As I said before, Rodriguez has enthused my writing, so there must be more to him. Well, Rodriguez’s home life and family life was what you’d imagine it to be a Mexican growing up in America, tough, to say the least. Having to deal with common Research Paper Research Paper Athletic Performance Using mind body connection The mind is a powerful tool. Athletes who are able to effectively use their mind have more success than those who cannot. Athletic performance can actually be improved using the connection between the mind and the body. That mind-body connection has given athletes positive reproducible results time and time again. The only barrier in the way of the athlete is learning the process that improves athletic performance by enabling the mind-body connection. Our minds tell our bodies what to do and how to react. For instance, athletic performance increases when the athlete links the mind-body connection and visualizes the specific event in their minds several times before the actual event. An Athlete’s Secret Weapon – Visualization What can an athlete do to gain the upper hand over his or her opponent who has the same fitness level, nutrition regime, and game experience? This is where sports psychology comes into play. An athlete can rise to the next level and surpass their opponents with the use of mental preparation. Visualization, also known as guided imagery, enables an athlete to create clear detailed images in their mind that they want to manifest as reality during their game. Using imagery, an athlete can put themselves in every situation possible and practice responding successfully. The outcome is reduced anxiety and mental involvement before ever stepping onto the playing field. Developing High Levels of Confidence Confidence is the keystone to performing at your best. When athletes are confident, their mind and body are relaxed allowing them to perform at their best. A confident athlete has been defined as "being able to be positive, motivated, focused, and emotionally in control when they need to be. There are a few things that can be done to ensure you have the highest level of confidence possible. First of all, engineer your approach to competition so that you are doing things that you have already successfully done in the past. Just knowing that you done it successfully before, will give you confidence. When you are reviewing your performance in your head, see it working perfectly. A confident athlete has the belief that he/she has what it takes to be successful no matter what is happening on the field/court.

Well I am here to explain why not and I will be comparing and contrasting three monotheistic religions which are: Judaism, Christianity and Islam. I will discuss the uniqueness of each religion regarding their beliefs and basic teachings. Also will be talking about each religion background information, on how they religion got started. Who were their founding fathers and how where they able to find their religion. I will explain the symbols and they kinds of food that each religion is alike and don’t eat alike. The first Religion I will talk about is Judaism it was formed 1300 B.C which is one of the most scholar date Abraham who was one of their forefathers. There is set to believe that there could be four founding fathers of Judaism. Who are God, Moses, Abraham and historical authorities? The original language of Judaism is Hebrews. The origin of Judaism is Canaan and that is a biblical name for the religion. That came about because of the Jordan and the Mediterranean River. The symbol for Judaism is the â€Å"Star of David†. The Star of David is a six pointed star made up of two triangles. Sometimes they refer the Star of David being called Megan David. Which in Judaism means the â€Å"Shield of David†? some Christians and Muslims have used the Star of David in previous years also sometimes associated with the King Of Solomon instead of King David. The sacred text is Tanakh which is an acronym of The Bible name Torah Nevi’im and Ketuvim. Our first five bibles are names after the Torah; Exodus, Numbers Leviticus, Genesis, and Deuteronomy. The place where the Jews worship is called the synagogue or sometimes the temple. There holy days are called Passover and Hanukkah. The Talmud was also the oral Torah and was compared to the rabbinical commentary. The leaders of Judaism are called Rabbis. Judaism today is much better and it is one the oldest religion that still exists today. Judaism started in a small nation by the Hebrews. So many years had passed with the Jews going through rough times. They suffered dispersion, persecution and occasional victory. As we look on the religion today we have at least 14 million Jews. Today is more complex which incorporates both nation and religion. This all comes down to strict adherence and ritual laws with more liberal attitude on religion beliefs. Judaism has been a major part in shaping the world today this is not in common western categories like race, religion, ethnicity or culture. Unlike Christians Judaism have been influenced by so many different contacts like Egyptians, Babylon and Persians. Christianity was formed 33 C.E and it was known for the traditional date for the death and resurrection of Jesus Christ. The founders of Christianity are Jesus, Peter and Paul. Many different scholars date the rise of Christianity as a r eligious belief system. Some of holy days are ester, Christmas, Good Friday, Palm Sunday and Ash Wednesday. Then in the first century under the leadership went over to apostles. Most Christian’s beliefs were center on the life of Jesus of Nazareth he was a teacher and he healed the first century Palestine. The symbol for Christianity is a Cross, and Dove some people claim their can be more. But the more common one is the cross that everyone can recognize. Teachings based on the themes of the kingdom of god, love of god and love of thy neighbor. We as Christians believed that Jesus rose from the dead three days after his burial, and made it possible for those who believed that sins can be forgiven and attain eternal life. The distinctive belief of mainstream of Christianity if the doctrine of Trinity. Meaning we view god as one god consisting of the three persons; the father, the son and the Holy Spirit. We as Christians Research Paper Research Paper The Atrocities at My Lai Massacre During the Vietnam War, there were lots of corruption and violence taking place. As an outcome of this war, there were many events and tragedies that are still remembered and looked back upon, but one act of cruelty stands above all the others. Because of the inhumane actions that were taken by U.S. forces, the corrupt leadership of Lieutenant Calley and the fact that this massacre was covered up from society for over a year, the My Lai massacre became know as the worst atrocity that occurred during the Vietnam War. To start off, the mass destruction that took place during the My Lai Massacre shows that this was in fact, the worst atrocity that took place during the Vietnam War. On March 16, 1968, U.S. soldiers entered the village of My Lai in northern South Vietnam. The soldiers had been searching for threats within the village, but soon determined that the women, children and elders living there, were not dangerous. ‘But rather than move on, the soldiers abruptly went on a murderous killing spree, massacring between 300 and 500 unarmed villagers over a period of several hours’ (Russell 703). Innocent unarmed people were murdered that day, with no means of protecting themselves. Hundreds of innocent people were slaughtered, â€Å"In terms of numbers of slain, the My Lai Massacre is by far the worst known U.S. atrocity case of the Vietnam War† (Cook and Martin 217). Not only did the soldiers murder hundreds of innocent people, but they also tortured them and forced them to suffer: During this time, the soldiers torched houses, raped dozens of women and children, and shot or stabbed terrified villagers who tried to escape. The American troops executed most of the villagers by lining them up in ditches and shooting them in heavy bursts of rifle fire (Hillstrom and Hillstrom 212). These inhumane actions taken by the U.S. forces in My Lai, are one of the main reasons that the My Lai Massacre is known to be the worst atrocity that occurred during the Vietnam War. This event was not only sick and cruel, but could also represent everything that was wrong with the Vietnam W ar. Ronald L. Haeberle was a photographer for the United States Army, and unfortunately, had a firsthand experience of witnessing the spiteful execution of these innocent people at My Lai. â€Å"Haeberle said that no Viet Cong were sighted nor were there any reports of Viet Cong fire in the village† (Cook and Martin 217). There was clear evidence that shows that no Viet Cong or even armed people were present when this massacre took place. â€Å"U.S. forces, Haeberle related, mechanically killed the civilians, some in their beds in huts. The murders were carried out; he said, with M-16 rifles and machine guns† (Cook and Martin 217). Not only were these people killed, but they were humiliated and treated much less than a person. It was much more than soldiers doing their duties, it was inhumane and unethical. â€Å"He said he saw as many as 30 American soldiers’ murder as many as 100 South Vietnamese civilians, many of them women or babies, many left in lifeless clumps. He describes the soldiers who did the shooting as ‘intent on what they were trying to accomplish. There was no feeling, nothing human about it. It was, for the most part, grim, though later some of the men tried to be humorous about leaving the bodies for the dogs and the rats’† (Cook and Martin 219). Soldiers recklessly lost control of themselves and took out all of their anger on the lives of these unarmed, innocent women, children and elders. GI’s forced these people to not only die, but to suffer as well. â€Å"‘The GI’s found a group of people- mothers, children, and their daughters. This GI grabbed one of the girls, in her teens, and started stripping her, playing around. They said they wanted to see what she was made of and stuff like that’† (Cook and Mart in 219). It was obvious that the U.S. soldiers acted excessively violent and took out all of their anger on innocent Research Paper Research Paper The Periodic Table and the Aufbau One of the biggest topics in the teaching and learning of chemistry is the use of the aufbau principle to predict the electronic configurations of atoms and to explain the periodic table of the elements. This method has been taught to many generations of students and is a favorite among instructors and textbooks when it comes to setting questions. In this blog I am going to attempt to blow the lid off the aufbau because it is deeply flawed, or at least the sloppy version of the aufbau. The flaw is rather subtle and seems to have escaped the attention of nearly all chemistry and physics textbooks and the vast majority of chemistry professors that I have consulted on the subject. The error comes from what may be an innocent attempt to simplify matters or maybe just an understandable slip as I will try to explain. Whatever the cause there is no excuse for perpetuating this educational myth. So what’s the problem? The aufbau method was originally proposed by the great Danish physicist Niels Bohr who was the first to bring quantum mechanics to the study of atomic structure and one of the first to give a fundamental explanation of the periodic table in terms of arrangements of electrons (electronic configurations). Bohr proposed that we can think of the atoms of the periodic table as being progressively built up starting from the simplest atom of all, that of hydrogen which contains just one proton and one electron. The other atoms differ from hydrogen by the addition of one proton and one electron. Helium has two protons and two electrons, lithium has three of each, beryllium has four of each, all the way to uranium which at that time, (1913), was the heaviest known atom, weighing in at 92 protons and 92 electrons. Neutron numbers vary and are quite irrelevant to this story incidentally. The next ingredient is a knowledge of the atomic orbitals into which the electrons are progressively placed in an attempt to reproduce the natural sequence of electrons in atoms that occur in the real world. Oddly enough these orbitals, at least in their simplest form, nowadays come from solving the Schrà ¶dinger equation for the hydrogen atom but let’s not get too sidetracked for the moment. The orbitals The different atomic orbitals come in various kinds that are distinguished by labels such as s, p, d and f. Each shell of electrons can be broken down into various orbitals and as we move away from the nucleus each shell contains a progressively larger number of kinds of orbitals. Here is the well-known scheme, First shell contains 1s orbital only Second shell contains 2s and 2p orbitals Third shell contains 3s, 3p and 3d orbitals Fourth shell contains 4s, 4p, 4d and 4f orbitals and so on. The next part is that one needs to know how many of these orbitals occur in each shell. The answer is provided by the simple formula 2ï  ¬Ã¯â‚¬  + 1 where ï  ¬ takes different values depending on whether we are speaking of s, p, d or f orbitals. For s orbitals ï  ¬ = 0, for p orbitals ï  ¬ = 1, for d orbitals ï  ¬ = 2 and so on. As a result there are potentially one s orbital, three p orbitals, five d orbitals, seven f orbitals and so on for each shell. So far so good. Now comes the magic ingredient which claims to predict the order of filling of these orbitals and here is where the fallacy lurks. Rather than filling the shells around the nucleus in a simple sequential sequence, where each shell must fill completely before moving onto the next shell, we are told that the correct procedure is more complicated. But we are also reassured that there is a nice simple pattern that governs the order of shell and consequently of orbitals filling. And this is finally the point at which the aufbau diagram, which I am going to claim lies at the heart of the trouble, is trotted out. The order of filling of

Definition and Examples of the Habitual Present Tense

Definition and Examples of the Habitual Present Tense In English grammar, the habitual present is a verb in the  present tense  used to indicate an action that occurs regularly or repeatedly. It is also known as the present habitual. Typically, the habitual present employs dynamic verbs, not stative verbs, and it may be accompanied by an adverb of frequency such as always, often, or  seldom. Examples and Observations He  runs every morning in  New York. Twice around the reservoir. I know, because I go with him. I dont run, but I go.  (Wil Haygood, Sweet Thunder: The Life and Times of Sugar Ray Robinson. Knopf, 2009)In the movie 50 First Dates, Lucy Whitmore wakes up every day with no memory of the previous day as a result of an automobile accident that has virtually eliminated her short-term memory.His wife buys daily the food for that day in a permanent market of small stores and booths in the plaza in quantities so small as to astound and amaze an American housewife.(May N. Diaz, Tonal: Conservatism, Responsibility and Authority in a Mexican Town. University of California Press, 1966)Joshua Stillman must be old but nobody ever thinks of what his age might be, he is so very much alive. He goes to the city every day and comes back early every afternoon. As he so seldom talks about himself nobody knows exactly what he does except that it has to do with books and small print.(Katharine Reynol ds, Green Valley. Grosset Dunlap, 1919) Adverbs of Frequency with the Habitual Present Present tense is also used with active verbs to describe something that happens routinely or habitually. Like the present tense that is used for general statements of fact, the habitual present tense does not limit routine or habitual activities to a particular time span. Instead, it suggests a timeless quality; that is, the habit or routine that happens regularly also did so in the past and will do so in the future. Hurran uses his truck to carry food and water to his familys tent camps in the desert. When the present tense is used to describe a habitual or routine activity, it may have an adverb of frequency with it. Each Saturday, Hurran drives into town to get food and water supplies. He washes and waxes his truck each week. (Linda Bates, Transitions: An Interactive Reading, Writing, and Grammar Text, 2nd ed. Cambridge University Press, 2005) The Habitual Present and the Present Progressive The habitual present . . . is used with dynamic verbs to encode situations that occur habitually over time, even if the action is not being carried out at the moment of speaking. For instance, referring to the following examples, Tim may not actually be working, nor the leaves falling at the moment of speaking. Nevertheless, the recurrent situation holds as the normal course of things and is appropriately referred to by the present tense. Tim works in an insurance company. Many trees lose their leaves in autumn. Again, it must be pointed out that the plain present tense used for habitual and other meanings contrasts with the present progressive, which encodes an actual occurrence of a dynamic action observed in the process of happening, as in Tim is working late today. The trees are already losing their leaves. (Angela Downing and Philip Locke, English Grammar: A University Course, 2nd ed. Routledge, 2006)

1.Is democracy inimical with 'Asian values' or 2. 'China's interests in the Asia-Pacific region are inherently incompatible with those of the United States,an - Essay Example In the Asia Pacific, where earlier Japan had been the only democracy, five new democratic states emerged by the mid-1990s. In 1986, the Philippines became a democratic country, the next year South Korea and Taiwan, in 1990 Mongolia, and in 1992, Thailand emerged as a democracy. These changes occurred in the presence of authoritarian rule in China, Vietnam, Burma, Singapore and Malaysia. However, it is stated that the emergence of electoral democracy, has to be devleoped into consolidation of democratic rule (Shin & Wells, 2005: 88). According to Berger (2004: 181), some of the â€Å"Asian values† that authoritarian governments emphasize are: obedience to authority, discipline, allegiance to community which has to be given priority over the individual, unity among ethnic groups, strong kinship with family and mutual economic activities, thrift, hard work, loyalty to the extended family, filial piety, and most importantly, respect for education. The Asia-Pacific region encompasses eighteen countries and territories which vary greatly in size and population from China to Singapore. Economically, China still belongs to the third world, whereas Singapore is in the category of a newly industrialized economy. According to Pempel (2005: 57-58), on a per capita basis, Japan is far ahead of China both in purchasing parity power GDP and in market GDP. Greater economic disparities are present between Japan and Vietman, and between Japan and Burma. Similarly, there are wide differences in religion, culture, historical associations, social traditions, language, ethnicity and political systems among the countries of the region (Yahuda, 2004: 9). Many of the divisions in the Asia-Pacific cut across state borders, create tensions between regional states, and increase the problems of nation building and consolidating state power. Further, the colonial legacy has resulted in territorial disputes among the Southeast Asian states, and led to

Advertising in Newspapers Research Paper Example | Topics and Well Written Essays - 750 words

Advertising in Newspapers - Research Paper Example Newspapers allow the usage of writings or photos in advertising or as a means of communicating information to the public. However, in advertising, most organizations often use both photos and writings in communicating to its various clienteles. Companies often design and use attractive or appealing photos alongside certain enticing words, to make customers purchase their desired products. How it Targets a Specific Group Newspapers are designed in a manner to ease the process of advertising and conveyance of information (Humphrey, 2003). Advertising in newspapers is used in varied ways. Advertisements in newspapers can be used to convey messages to a certain targeted group. Newspapers consist of different sections such as the sports section, politics sections and the social sections. Advertisers, therefore, can use these sections to target a certain group having the potential of purchasing the products in the market. For instance, when advertising sports attires, it is wise to post th e advertising details within the sports section. This ensures that the advert posted reaches the intended customer. Additionally, certain newspapers often provide free magazines covering a certain topic that is of major concern to the public. Some of them talks about lifestyles, social aspects, relationships and political aspects. Such magazines can also be exploited as a suitable platform for targeting a certain group. However, despite this being an effective approach, it is also imperative to consider other factors, which comes into play for the effectiveness of the advertisement. For instance, the advertising company must ensure that the targeted group is able to read and comprehend the conveyed message. The Primary Role of a Newspaper The newspaper has numerous roles, the primary one being to inform the public. Other roles of the newspaper are to educate and advertise various products on behalf of a certain company (Farell & Cupito, 2010). Since advertising also aims at informin g the public about new products in the market, the advertising process thus fits within the primary role of newspapers. Advertising helps in informing the public on the new prices in the market and the modifications done on various products. This empowers the public to make informed decisions regarding their desired products or services. It is advisable for organizations to use both visual aids and wordings in their adverts, when using newspapers as an advertising medium. Visual aids add value to adverts thus making them appealing to the targeted group. Newspapers act as a support medium, in most cases. Most of the information documented or printed in newspapers are often not directly from the person conveying the message. The writings are often edited or rewritten by a different individual (newspaper editors), who never participated in writing the original document. This, therefore, makes the newspaper a support medium of conveying information. However, in some instances, newspaper s always print direct information or quotes from a certain source. Although this does not mean that, it is a primary medium. This is because the information obtained was initially meant for a different group as opposed to the ones addressed by the newspaper. Accessibility Newspapers are easily accessible thus can be reached by a number of potential buyers. For instance, in certain countries such as Netherlands, newspapers are distributed for free thus anyone can access them, even young children. Moreover, even if they are being sold in certain countries, the cost incurred when purchasing is often affordable to a significant part of the

Accidental Death of an Anarchist Essay Example for Free

Accidental Death of an Anarchist Essay Q) Critically analyze the Figure of Madman in Dario Fo’s play The Accidental Death of an anarchist. A) Dario Fo’s play The Accidental Death of an Anarchist (1970) lies in the category of revolutionary theatre that challenges the fascist regime of Italy. The play is a farce based on events involving a real person, Giuseppe Pinelli, who fell or was thrown from the fourth floor window of a Milan police station in 1969. He was accused of bombing a bank. The accusation is widely seen as part of the Italian Far Rights strategy of tension. Just like Fo’s other play, this play is also funny and subversive and shows a strong preference for the culture and traditions of the ordinary people and a commitment to the left wing politics. The play moves quickly through a series of farcical situations and exposes the hypocrisy and anti- people character of the bourgeois society and the so called sacred institutions- the police, the judiciary, the religion and the media. The play was originally written and performed in Italian in 1970 and first English translation was done in 1979. Central to the play is the character of The Madman, who is the prime protagonist of the play. Through the story of the madman in a police station Dario Fo has a created a classic example of exquisitely political theatre with a comedy that begins from being realistic, (the stage setting is of a realistic, ordinary police station) moves towards the frankly implausible (the madman, the inspector, the superintendent and the constable singing the song of anarchists in the police station), reaches to the level of grotesque (the constant punching and kicking of Bertozzo by the police officials, and the falling eye) until it ends with a hilarious and ludicrous climax. He (the madman) invents dialogue based on a paradoxical or on real situation and goes on from there by virtue of some kind of natural, geometric logic, inventing conflicts that find their solutions in one gag after another in correspondence with a parallel political theme, a political theme which is clear and didactic. You are moved and you laugh but above all you are made to think, realize and develop your understanding of everyday events that had escaped your attention. Franca Rame on The Character of Madman in Accidental Death of an anarchist The madman is not just a character in the play, but he acts as a literary device in the play. He provides most of the humor content of the play. The madman is whimsical and he constantly contradicts other characters as well as himself. His series of logical/illogical arguments becomes impossible to tackle and it frustrates the Police Department. Even though being termed as psychologically unfit, the madman appears to be the most intelligent character in the play. He ridicules the police officials for missing out on the basic concepts of English grammar and the use of the most important â€Å"COMMA† that changes the meaning of a sentence. He dictates the terms of law and judiciary to police officials. He is extremely sarcastic. He ridicules the superintendent for assuming the railway man planted the bomb in railway station without any substantiate evidence and sarcastically rebukes the â€Å"kindergarten logic†. The people in power appear to be inhuman and brute in their actions, and the â€Å"sacred† governmental place, the police station appears to be a madhouse or a slaughterhouse. The madman, even though he is mad appears to be the sanest character in the play. In fact, he appears to be directing the play according to his wishes. Suffering from a disease of enacting people, he sees the world as a stage and other people as his fellow characters. He warns Bertozzo that soon he is about to be punched by Pisani and warns him to duck. Bertozzo ignores the directorial warning of the madman. Later he tells the superintendent to stop playing around and â€Å"keep to the script†. The actions of the play move around as the madman says and everyone does what he asks them to. Bertozzo, who defies the madman’s instructions, keeps on getting punched and thrown out. Hence, Fo, in his play, takes the power out from the hands of the police, the judiciary, and the media and gives it to the representative of the lower section of society, the madman. By pretending to be, in turn to be various figures of authority – psychiatrist, professor, magistrate, bishop, forensic expert – the Maniac forces officials to re-create the events with the purpose of showing the inconsistencies in the official reports of Pinelli’s â€Å"leap† and to confess their responsibility in the anarchist’s death. The madman manages to create mayhem within the policeman, representatives of law and order and figures of authority are made to appear ridiculous and a target of laughter. He exposes how people in power are all in collusion to save their own. Now I am about to show some of the theatre/TV productions of the play and give brief comments on how the character of madman operates in them. Firstly, take a look at the 1983 British TV movie that was telecasted on Channel 4. In this production, the original Italian setting is mixed with contemporary references to Thatchers Britain. 1) In the beginning itself, various impersonations of the madman are shown pointing towards the crime committed by him. 2) The madman constantly points towards the audience that is standing upwards, and the crew, and chats with them. And he talks to the director about the censorship laws on television in Britain, when the inspector says The â€Å"F† word. (5 minutes 30 seconds). 3) In the play, not only the madman enacts different roles, but the same constable is used on the 2nd floor and the fifth floor and also as a liftman. The madman here is concerned with anti materialist sentiment as well. The madman remarks about the fact low budget of the show saying, â€Å"Couldn’t they get a different actor to play you? Who’s directing this thing, Ian MacGregor?† (17 minutes) and the Maniac, â€Å"This is commercial television in crisis!† Similarly, in The IIT production of the play, which is performed in India, in Hindi, the references are converted according to Indian settings and sentiments. 1) The University of Padua is converted into University of Patiala. The madman teaches the Hindi vowels to the constable and the policeman. (4:30) (A aa e ee) 2) The police inspector in the 6th minute of the play says to the madman that he’s madder than the madman. As I said above the madman appears to be the sanest of characters in the play. My fair Heathen Productions in their September 2007 production actually used a woman for the role of the madman. Hence the madman is enacting as a madman from the beginning and in fact is a mad woman. This does not bring a significant change to the play, except probably the so called marginalized figure of a madman, becomes a more marginalized figure as in this production it’s a woman, who comes to a male dominated domain and creates havoc in the lives of the men from powerful sections of the society. Hence, different theatre companies have used different types of madman to heighten the message of the play.

Television Violence Essay -- essays research papers fc

Television violence and its effects on viewers has been a controversial issue for many years. Some viewers believe that there is an increasingly large amount of violence on television and this widespread public concern has "led to calls for stricter controls on the depiction of violence in programmes" (Gunter and McAleer 1990:92). Exactly how much violence is there on television though? Many cultivation theorists have studied this, acquiring data in the form of content analysis. They agree on a definition of a violent act, for example Gerbner in his study used the definition, "an overt expression of physical force against self or other, compelling action against ones will on pain of being hurt or killed, or actually hurting or killing" (Gunter and McAleer 1990:94). This is an objective definition that can then be used to count the number of violent acts in whatever is being observed. Halloran and Croll (1972) used this technique to establish the amount of violence on British television in comparison with that of American television. For one week in April 1971, they observed the news, fictional drama, current affairs and documentaries on BBC1 and ITV Midlands and counted the number of violent incidents using Gerbner’s definition of violence. It was found that on average, 56% of British programmes contained some violence with four incidents of violenc e per hour. This was in comparison with American television which contained some seven incidents of violence per hour and where it was considerably more prevalent than on British television (Gunter and McAleer 1990:97). Focusing now on British television and violence, we can analyse Guy Cumberbatch’s research on television violence in 1987. He looked at all types of television programme focusing on four separate weeks between May and September 1986. All four channels were reviewed, totalling 1412 hours of television (930 BBC programmes and 1146 ITV and channel four programmes). He found, using his own definitions of a violent act, that 30% of all programmes contained some violence with an average of 1.14 acts of violence per programme (Gross 1992:455). It was also found that there was much more violence on television after 9pm and that violence was rare in children’s television programmes other than cartoons. It has been questioned however whether the violence in cartoons should actually b... ...er factors have also shown to be influential in this cause and effect relationship between television violence and violent behaviour. Such factors as age, gender, parental influence and amount of viewing contribute to how influential television violence is on an individual’s behaviour. Findings are still however inconclusive in this debate, although a large proportion of the evidence does appear to strongly favour the hypothesis that viewing violence on television does have an effect on a viewer’s violent behaviour. As a Washington Post article states "the preponderance of evidence from more than 3000 research studies over 2 decades shows that the violence portrayed on television influences the attitudes and behaviour of children who watch it" (Oldenburg 1992 cited at http://maple.lemoyne.edu/~hevern/ericdig.html).

Importance of Books in Life

Learning is a significant process in human being life. It is self-evidence that human development can not stand without a good learning. To reach that target, people always search the appropriate ways. Besides, the mains important elements that help people to learn are books and experiences because of their unlimited benefits. The book is a valuable source of knowledge that consists of infinite benefits. It transports us into different worlds and cultures, as well as, it informs us about ancient civilizations and lore.In addition, it helps us to learn about new technologies and literature. It allows speaking languages fluently and to communicate spontaneously. Therefore, the book can be faithful friend and the nearest into us which can guide us to how to behave in our practical life. Our practical life is also, in addition to books, based on experience. This latter is a crucial element that assists to overcome obstacles. Experience keeps our minds aware of the way to solve some probl ems, for example, if someone re-confront a problem, it would be easy for him/her to solve it.Experience also could indicate to us the suitable method of living in our life. In conclusion, learning is a strong challenge that requires patience and efforts. Books and experiences are the best manners of learning because of their vast importance and great advantages. Books can play a very important role in shaping our life because we can learn lots of things easily from books. Books provide a great solution in front of us to learn about anything and increase our knowledge level.Therefore, large numbers of people around the world read books because they find them very useful. Books are present in our world from many centuries in different forms and shapes of books are changing with time. Today, we can find books in pdf or audio formats as per the need of people. Though, all these books provide same help by increasing our knowledge levels. People can easily buy books from various book stor es available in market or they can use online web stores to order bestselling books. Best Answer – Chosen by VotersThe importance of reading books is gaining new insight or perspectives on issues that matter to the reader that helps them to have a new understanding of the world around them. Readers can apply the insight in everyday life or as a way of building upon the knowledge that already encompasses their mind and enrich their lives. The importance of books are also found in how new discoveries pertaining to history are uncovered and/or revealed where the relevance of this the new information needs to be applied or amended in what already exists about a particular issue, topic or event.Thus, â€Å"new† books on existing issues are important because sometimes facts â€Å"change. † Books are a tangible, valuable record of our world. Sure we have the internet and computers with vast amounts of information stored in them but all of history isn't in a computer. H istory, the stories of civilations long gone and ancient languages forgotten are somewhere in a book. Books are there so you can learn, imagine and sometimes escape from the world around you. There is nothing like sitting down with a new book, the pages crisp and fresh, and reading about a love story, or a horrible murder.Books are an outlet for many people. For some it is their way of expressing their imagination†¦ writers create so we can read and let our minds take us to a different place, a different time, maybe even a different world. For others, books are an escape. When the world gets to be too crazy and you need to escape you can pick up a book and forget about the world around you. Books enables us to see life through other peoples eyes. People are able to communicate their view of the world to a large audience.Books also enables us to understand other cultures, which in turn enables us to relate better with others. Books can have a profound effect on society and the w orld because they enable an individual to change the world. A single book by a single author can make a huge difference in the whole world. Think ‘Tuesdays with Morrie', ‘God has a dream' and you begin to see the role of books in society and why they are important. Books glue people and cultures together. But unfortunately they can also be used to do just the opposite of the above.

Online gaming Essay

Is trying to attain the needs of the student with the new scheme of education. The K-12 entails the addition of Music, Arts, Physical Education and Health (MAPEH) subject in grades 1, 2 and 3. Music is a colorful sound that we hear after birth. Playing music for infants in their first year provides for enhancement and benefit in future education. Music has different meaning to every individual. It works as a means of learning, relaxation, and fun. Everyday, young people spend more than four hours watching television, one hour using a computer and one hour of playing video games. No wonder why this era has become the â€Å"digital age†. We can also refer to the current era as a visual age. The demand for new abilities also transformed the workplace. â€Å"The secret sauce comes from our ability to integrate are, music and literature with the hard sciences, that’s what produces an iPod Revolution or a Google.† Friedman says. Today arts are needed by our young people as a means of expression, communication, exploration, and imagination. Arts help us strengthen the critical thinking skills. It also develops cognitive and creative skills. Physical Education plays a critical role in educating the whole student. Like other academic courses of study, physical education is based upon rigorous national standards that define what students should know and be able to do as a result of participation. It is unique to the school curriculum as it is the only program that provides students with opportunities to learn motor skills, develop fitness, and gain understanding about the importance of physical activity. Students will be provided an individualized, developmentally appropriate, and personally challenging instructional program that will advance the knowledge, confidence, skills, and motivation needed to engage in a lifelong, healthy, active lifestyle. In the propose study of the proponents, the students are going to apply and use the application not just for the entertainment but for them to learn on  something like any other word games. But with this study the students are expected to learn words from the subject itself. Statement of the Problem This study find answers to the following questions: 1. Can the new game be an effective tool for learning while keeping players entertained? 2. Can the new game be an effective way of teaching MAPEH and can it be equally effective for enhancing the critical thinking skills of the players? General Objectives The general objective of this study is to implement a word game that enables the learning of the MAPEH subject more exciting. By providing a learning environment that is exciting and entertaining, the hope is to increase learning effectiveness. This game will act as a future learning tool that will assist in the problems that teachers face in expanding a child’s vocabulary. The same can be said for a teacher trying to teach students where Cebuano is not their first language. This application can make players more determined to learn and to advance in the language by forming as many words as they can. It will let the players build and expand their vocabulary and strengthens the advantages of learning and playing this game. Specific Objectives To create an application that is effective in teaching MAPEH subject with fun ï‚ · To create an application that enhances the players’ critical thinking skills Conceptual Framework The concept of the game is that the player inputs the user name after the submission, the player has two options in selecting the type of game, whether a timed game or a non-timed game. If the player selects timed game, the player can select among the four categories; Music, Arts Physical Education, or Health. If the player selects random category, there will be two (2) minutes allotted time for the player to search for possible word/s and if the player find the word/s there will be an additional ten (10)  seconds added to the player’s remaining time. In non-timed game, there will be a leveling stage of difficulty and the player will construct for possible answer in every random category questions. There is a rule in giving hint, in non-timed game, there is a help button for words that were not yet found. The player can hit the hint button every twenty (20) seconds only to have discipline in using hint. The timed game scoring is based on the number of words find while the non-timed game ranking score is based the length of words found. To make the game more interesting and exciting, the proponents added a hall of fame list , wherein it has a ranking of the top 10 players displaying their statistics like longest word found and their achievements that they gain from timed and non-timed game. However, if the player wanted to quit the non-timed game, he can hit the menu button and quit. If the player losses in timed game, there will be a notification box that will pop-up in which the player could choose and decide whether to try again or quit the game and return to main menu. Figure 1.0 The process of the Gameplay Simulation Scope and Delimitation of the Study Scope The study focuses on developing a PC game application of a book worm style game where it contains many categories that are related to MAPEH subject such as Music, Arts, Physical Education and Health. This game, players can choose whether it is timed game or non-timed game. Players can play with different category such as Music, Arts, Physical Education and Health or player can choose a random category. This game has a time limit wherein the player needs to complete the word/s before the time ends. If they can answer questions then points will be given and will be placed in a ranking or players can quit the game and return to main menu. In timed game, players can choose different category or a random category. Players will get a score for every word and if they have the biggest scores they will be put first in a ranking. Delimitation The game will only delimit the following: o It will only focus on related MAPEH subject. o It will only cater 2D Graphics and does not project 3D graphics. o It will only use materials that are educational. All inappropriate topics will be excluded. Significance of the Study Students – This research is significant to the students that find MAPEH as a difficult subject. Teachers – This research is significant to the teachers for they will also learn new learning tools or other way on how to teach MAPEH subject. Players – This research is significant to anybody that plays games since this game can enhance the players critical thinking skills of the subject MAPEH . Future Researchers – Anybody that wished to create the same study can use this as a reference. They will find this helpful. Definition of Terms 2D computer graphics – 2D computer graphics are digital images that are computer-based. They include 2Dgeometric models, such as image compositions, pixel art, digital art, photographs and text. 2D graphics are used every day on traditional printing and drawing. Computer Gaming – Computer gaming is a type of video game playing that is played on a personal computer, rather than a dedicated video game console. CHAPTER II REVIEW OF RELATED LITERATURE AND STUDIES This chapter contains the review of related literature and related studies that contains relevant and useful information in conducting the research. Related Literatures Study examines potential positive effects of video games Video games have become part of our life. All age groups have a varying degree of experience with video games. Most games have been made for entertainment purposes. Nowadays, there is increasing controversy over the effects of video games. Parents worry about the negative effects of computer gaming on children, they’ve emphasized on the violent behavior and addiction of computer games. However, there are some positive effects which could benefit a person from playing video games. According to Snodgrass (2011), an associate professor of anthropology at Colorado State, video games can have potential positive effects on people. This was researched by examining the  different types of video gaming experiences and the effects they can have on players’ lives, including their self-reported levels of stress, life satisfaction and happiness. In video games, players could develop avatars and complete tasks in cooperation with other players. The complex and highly interactive nature of the game can lead players to feel as though they have become part of a vividly compelling alternate universe. The American Psychological Association (APA) researchers assessed their problem-solving ability by examining the types of cognitive, goal-oriented, game-oriented, emotional and contextual statements they made. Younger children seem more interested in setting short-term goals for their learning in the game compared to older children who are more interested in simply playing and the actions of playing. (Ostrovsky, 2008) Bookworm Deluxe Bookworm deluxe has similar concepts to Mother Tongue Bookworm. The game utilizes 2D graphic visualization, from a grid of available letters; players connect letters to form words. As words are formed, they are removed from the grid and the remaining letters collapse to fill the available space. The players are given a board filled with lettered tiles, and they have to string them together to form words. The player get points for each word and longer words are worth more points. A major benefit of the game is that it increases a player’s vocabulary. (Mueller, 2005) Scrabble Scrabble has been around for more than half a century now. Scrabble is a word game in which two to four players score points by forming words from individual lettered tiles on a game board marked with a 15-by-15 grid. The words are formed across and down in crossword fashion and must appear in a standard dictionary. There are three ways in which the player could benefit from playing this game. One of which is that it builds vocabulary, second is it helps one improve spelling and lastly in developing the skill of anagramming. The game application made by the proponents used this game as inspiration for the board game concept. (Rooni, 2010) Boggle game Boggle game or most commonly known as word factory is a word game designed by Allan Turoff. The game is played using a plastic grid of lettered dice, in which players attempt to find words in sequences of adjacent letters. The game is intended to help children learn to recognize letters and words, to practice hand-eye coordination, and to learn the correct spellings of basic words. (Nickerson, 2007) Synthesis The above mentioned related literature and studies, the proponents viewed that the proposed game application would be feasible and would significantly help those students most specially Kindergarten to Grade 3 students who are under the K to 12 program of the Department of Education. Children nowadays have access to technology that was not available in previous generations and therefore they have a unique opportunity to use this technology to aid in how they learn. By reversing the negative effects of video games, there are benefits that could be gained by players while having fun at the same time. CHAPTER III METHODOLOGY In this chapter, the proponents discussed the method used in this study and the different procedures in the development of the research. Moreover, it also included the research locale, design procedure, design instrument and the timeline of the study and how the gathered data collected and analyzed. http://www.sourcecodester.com/visual-basic/educational-computer-game-thesis.html

Calcium Carbonate and Ca2+ Ions Essays Calcium Carbonate and Ca2+ Ions Paper Calcium Carbonate and Ca2+ Ions Paper Experiment. EDTA Titration of Ca2+ in an unknown solution Experiment. EDTA Titration of Ca2+ in an unknown water sample Modified 9/2012 Objective: The most common multivalent metal ions in natural waters are Ca2+ and Mg2+. In this experiment, you will find the total concentration of calcium ions that can react with EDTA with the assumptions that EDTA reacts 1:1 with metal (Ca2+) ions. Equipment 250-mL Erlenmeyer flask (3) 50-mL Buret Ring-stand and hardware Desiccator 400-mL Beaker 500-mL Vol. flask 250-mL Vol. flask 1. 0-mL Vol Pipette 100-mL Grad cylinder Hot plate Safety and Waste Disposal Chemicals Buffer (pH 10): Add 142 mL of 28 wt % aqueous NH3 to 17. 5 g of NH4Cl and dilute to 250 mL with water. Eriochrome black T indicator: Dissolve 0. 2 g of the solid indicator in 15 mL of triethanolamine plus 5 mL of absolute ethanol. 50 wt % NaOH: Dissolve 100 g of NaOH in 100 g of H2O in a 250-mL plastic bottle. Store tightly capped. When you remove solution with a pipet, try not to disturb the solid Na2CO3 precipitate. Discussion: Hard water is due to metal ions (minerals) that are dissolved in the ground water. These minerals include Ca2+, Mg2+, Fe3+, SO42-, and HCO3-. Generally hard water arises because rainwater moves through limestone, CaCO3 underground that occurs in our area to the aquifer. This is why we measure hardness in terms of CaCO3. The concentration of the Ca2+ ions is greater than the concentration of any other metal ion in our water. The determination of water hardness is routinely used to measure the quality of water that the general public uses. Originally, water hardness was defined as the measure of the capacity of the water to precipitate soap. Hard water is not a health hazard since the main chemical in hard water is calcium. People regularly take calcium supplements. In fact, hard water can be a source of necessary minerals (calcium and magnesium) that is necessary for good health. Indeed, the National Academy of Science go so far as stating that that consuming extremely hard water could be a major contributor of calcium and magnesium to the diet. The problem with hard water is that it cause soap scum, clog pipes and clog boilers. Soap scum is formed when the calcium ion binds with the soap. This causes an insoluble compound that precipitates to form the scum you see. Soap actually softens hard water by removing the Ca2+ ions from the water. When hard water is heated, CaCO3 precipitates out, which then clogs pipes and industrial boilers. This leads to malfunction or damage and is expensive to remove. There are two types of water hardness, temporary and permanent. Temporary hardness is due to the bicarbonate ion, HCO3-, being present in the water. This type of hardness can be removed by boiling the water to expel the CO2, as indicated by the following equation: HCO3- (aq) ? H2O (l) + CO2 (g). Because bicarbonate can be removed it is classified as temporary hardness. Permanent hardness is due to the presence of the ions Ca2+, Mg+2, Fe3+ and SO4-2. Because boiling cannot eliminate this type of hardness, the water is said to be permanently hard. The table below shows the degree of hardness of the water in terms of its calcium carbonate concentration in ppm and grains. Hardness rating Soft Medium Hard Hard Very Hard Concentration of Calcium Carbonate (mg/L or ppm) 0 75 75 to 150 150 to 300 300 and greater Concentration of Calcium Carbonate (grains/US gallon) 0 to 5. 2 5. 2 to 10. 5 10. 5 to 21 21 and greater Permanent hardness is usually determined by titrating it with a standard solution of ethylenediamminetetraacetic acid, EDTA. The EDTA is a complexing, or chelating agent used to capture the metal ions. This causes water to soften, but the metal ions however, are not removed from the water. EDTA simply binds the metal ions so that the ions do not precipitate to form soap scum. EDTA is a versatile chelating agent. A chelating agent is a substance whose molecules can form several bonds to a single metal ion. Chelating agents are multidentate ligands. A ligand is a substance that binds with a metal ion to form a complex ion. Multi-dentate ligands are many clawed, holding onto the metal ion to form a very stable complex. EDTA can form four or six bonds with a metal ion. It is frequently used in soaps and detergents because it forms complexes with calcium and magnesium ions. The ions in hard water are bound to the EDTA and cannot interfere with the cleaning action of the soap or detergent. EDTA is also used in foods. Certain enzymes are responsible for food spoilage. EDTA is used to remove metal ions from these enzymes. It is used to promote color retention in dried bananas, beans, chick peas, canned clams, pecan pie filling, frozen potatoes and canned shrimp. It is used to improve flavor retention in canned carbonated beverages, beer, salad dressings, mayonnaise, margarine, and sauces. It inhibits rancidity in salad dressings, mayonnaise, sauces and salad spreads. In this lab you will be asked to determine the total permanent hardness. EDTA grabs all the metal ions in the water, not just the Ca2+ ions. This gives us a value that is not truly the concentration of Ca2+ ions. This causes an experimental error of about 1%, which is acceptable due to the fuzzy endpoints in this type of titration. Erio-T indicator or Eriochrome Black-T indicator is used in this titration. When it is chelated or acidifies, it produces a Pink-Red solution. When it is not chelated and under basic conditions it is Blue. The three pictures show the end point in this titration. There is a 1-drop difference of 0. 01 M EDTA between the first and second pictures and between the second and third pictures. Two or three seconds were allowed for colors in the second and third pictures to develop after adding the additional drop. In each case the solution was thoroughly mixed. This color change from wine red to violet to blue is due to the compact nature of the complex. Experiment. EDTA Titration of Ca2+ in an unknown solution PROCEDURE Modified 9/2012 1. Dry Na2H2EDTA. 2H2O (FM 372. 24) at 80 ° C for 1 h and cool in the desiccator. Accurately weigh out ~ 0. 6 g and dissolve it with heating in 400 mL of water in a beaker. Cool to room temperature pour into a 500-mL volumetric flask. , mix and dilute to the mark. 2. You should practice finding the end point several times by adding a little tap water in a clean beaker and titrating with EDTA. Save a solution at the end point to use as a color comparison for other titrations. 3. Pipet a 1-mL sample of unknown into a 250-mL flask and fill to the mark with deionized water. Mix thoroughly. From this 250-mL stock solution draw 4, 50mL aliquot samples and place each aliquot in 250mL Erlenmeyer flasks. To each sample, add 3 mL of pH 10 buffer and 6 drops of Eriochrome black T indicator. To the first 50-ml solution, titrate with EDTA from a 50-mL buret and note when the color changes from wine red to blue. 4. Repeat the titration with the next three samples to find an accurate value of the total Ca2+ concentration. Perform a blank titration with 50 mL of distilled water and subtract the value of the blank from each result. 5. Upon completion of the experiment, discard all solution in a chemical waste bottle and wash out the glassware. Be sure to dry your buret in the upside down position. _________________________________________________________ Calculations – Analysis: Analyte Ca2+ The reaction of Ca2+ ions with H2EDTA2- takes place with a 1:1 stoichiometric ratio: Ca2+ + EDTA2- ? At the end point of the titration, 1-equivalent of Ca2+ reacts with one equivalent of H2EDTA2-. 1 eqv Ca2+ = 1 eqv H2EDTA2-; equivalent Ca2+ = [H2EDTA2-] Vol EDTA CaH2EDTA. Recall that the analyte (we call this unknown solution) was prepared by taking exactly 1-mL of the unknown solution and diluting in a 250-mL volumetric flask (we will call this the stock solution) 50-mL aliquot (call this the analyte) of this solution was then titrated against EDTA.
