Rock and Roll vs Rap Essay Example | Topics and Well Written Essays - 500 words

Rock and Roll vs Rap - Essay Example Soon the American rock style began to influence other genres. Places like Southern California produced their own varieties of pop music, such as surf. Young adults and teenagers across the country were playing in amateur rock bands, laying the roots for local scenes which would pave the way for garage rock and the so-called San Francisco Sound. Rock has encountered several stages of development since the beginning of the 50s, and the tendencies in modern rock include alternative bands (Radiohead, Muse), so-called pop-rock (Blink-182, Green Day) and others (George-Warren 26). Rap music in its widely recognized form appeared much later than rock and roll. The roots of hip hop music are in West African and African American music. Originally, early rappers of the 70s focused on introducing themselves and others in the audience (the origin of the still common practice of "shouting out" on hip hop records). These early performers often emceed for hours at a time, with some improvisation and a simple four-count beat, along with a basic chorus to allow the performer to gather his thoughts (such as "one, two, three, y'all, to the beat, y'all"). The 1980s saw intense diversification in hip hop, which developed into a more complex form.

Discussion board forum - Assignment Example Concurrently, it is domineering that ethical issues are considered during the formulation of the evaluation plan; likewise, the most common and essential considerations during the process include: informed consent, voluntary participation, do no harm (Beneficence), respect for confidentiality and anonymity, respect for privacy and assessment of only the relevant components. Informed consent is considered to be the most major ethical issue in conducting research and most of the experienced researchers give it the definition of a person expressively, willingly and logically, and in a clear and manifest way gives his consent (Deborah 2003). Basically, it is one of the most outright ways that a person’s autonomy is protected as it circles around that particular person being fully informed about the evaluation being conducted. The informed consent ethic seeks to integrate the rights of self-governing participants through autonomy and also prevent assaults on the integrity of the patient and protect personal freedom and genuineness (Johnstone 2009). Any additional information should also be provided in any event that the participant becomes distressed in any way since the main purpose of informed consent is that the participant is able to make informed decision as to whether they will participate in the evaluation or not. Normally, voluntary participation goes hand in hand with the informed consent ethic and means that the people participate in the evaluation free from intimidation and they are free to withdraw their participation at any time without negatively impacting on their involvement in future services or the current program and relationships with any of the researchers or research bodies involved (Deborah 2003). Sometimes there can be a lot of challenges especially in situations where one has the task of encouraging high risk youth to become engaged in a program hence making the situation difficult mostly when the

Genetically modified (GM) foods Essay Example for Free

Genetically modified (GM) foods Essay What does a tomato, soybean, and McDonald’s French fry have in common? They are all some of the most commonly genetically modified foods sold on the market today. By using the genetic information from one organism, and inserting or modifying it into another organism, scientists can make food crops stay fresher, grow bigger, and have the crops create their own pesticides. Nevertheless, the technology to modify genes has surpassed its practicality. Genetically modified foods need to be removed from everyday agriculture because of the threat they pose to human health, the environment, and the impact on global economy. Genetically modified (GM) foods could produce new toxic substances, and/or allergens. A gene from the Brazil nut was inserted into the DNA of a soybean plant to increase the nutritional value of the soybean. However, this particular gene in the GM soybean also produced an allergen (a substance that causes allergic reactions in people). Fortunately, the plant was not put into production (McHughen 119). Another example is of a GM tomato called â€Å"FLAVR SAVR†. The tomato is larger, tastier, and stays fresher longer than commercial tomatoes on the market. Combining conventional tomato genes with the genes of an arctic trout produces the â€Å"FLAVR SAVR†. Nevertheless, questions such as â€Å"Will people with sea food allergies be able to consume the tomato?† and â€Å"Will the trout genes in the tomato enable new bacteria growth, and thereby make the tomato hazardous to eat?† have still not been answered. This causes the â€Å"FLAVR SAVR† to be a potential hazard to human health (McHughen 14, 112). Since technology is new with regards to genetics, there is no real way of knowing whether genetically modified foods would take a negative impact on the body. An incident that occurred in 1989 concerning the nutritional supplement L- Tryptophan is one way of testing the long-term effects of a GM food (Background on L-tryptophan and 5-hydroxy L-tryptophan and the eosinophilia myalgia syndrome, U.S. Food and Drug Administration). The manufacturer had apparently altered its manufacturing process to speed up production, and had not realized the toxic side effects. However, it caused a potentially fatal illness called Eosinophilia Myolgia Syndrome in which 37 people died and 1500 more were permanently disabled (Background on L-tryptophan and 5-hydroxy L-tryptophan and the eosinophilia myalgia syndrome, U.S. Food and Drug Administration). Therefore, it was taken off the market shortly after the reports of widespread illness among consumers of the supplement. Another two examples of diseases that have been created by GM crops are glufosinate (Hart 21), which causes birth defects in mammals, and glyphosate (Hart 88), which is now linked to non-Hodgkin’s lymphoma. Therefore, it is evident that the general public is the guinea pig for GM food, and today’s drugs may not be able to combat the diseases that may arise from eating the food. Superbugs are created when genes transfer from one species to another, and if an antibiotic-resistant or pesticide-resistant gene were to transfer from an organism into a disease creating bacteria, then an antibiotic-resistant or pesticide-resistant bug would be created (Miller 83). This applies to bacteria and viruses that are symbiotically related. Gene modification is indirectly making life resistant to diseases, and these bacteria and viruses will adapt to the new form of life and create new disorders. Furthermore, GM crops may make the â€Å"normal† biological pest spray obsolete. This is because pests will soon develop resistance to the spray because of the widespread planting of GM crops. Nevertheless, superbug pesticides have not yet been manufactured, nor have superbug antibiotics been created (Miller 92). Consequently, the health risks for humans through superbug infections or by eating GM food is very serious, and the consequences that may come about have the potent ial to be life threatening. Genetic engineering of food crops has the potential to affect the biodiversity of a region in effectively two ways. First, wild populations of weed may be replaced by GM crop/weed, due to the GM crop spreading outside the crop field and interacting with natural weed and slowly becoming GM weed. Since GM crops are produced to be resistant to pesticides and herbicides, there is the possibility that they could invade wild grasslands and other places and prosper because of these special characteristics. If this happened, the native grasses would be unable to compete and biodiversity would be lost in these regions. Also, many genetically engineered crops contain anti-viral genes and there is the potential that these genes could combine to form new and dangerous strains of viruses, which could destroy specific crops. Although, to date, there is no direct evidence of these occurring naturally, the potential is clearly increasing (UK Agricultural Biodiversity Coalition. What is happening to Agricultural Biodiversity?). The second way in which the biodiversity of a region is potentially affected is by the decreasing crop varieties that are being planted. This is a problem already existing in agriculture today, and results in a loss of genetic variety within crop cultures. Farmers being forced to use only patented seeds are an example of a potential decrease in biodiversity. If traditional seed varieties are used, farmers will be at a financial disadvantage due to better tasting, better looking crops produced by farmers using GM seeds. In the U.S., and some other countries, laws have been passed and are currently in effect stating that the use of non-patented seeds is prohibited. This will restrict the crops to a few species, leaving them more at risk to new pests that may form (UK Agricultural Biodiversity Coalition. What are the underlying causes of the Losses of Agricultural Biodiversity?). The European community is by far the most anti-GM, so to speak, when it comes to the retail of GM food in their supermarkets (Tackling Food Safety Concerns over GMO’s, Consumer attitudes and decision-making with regard to genetically modified food products). Regulations are being imposed on the European Parliament, individual European nations, and some stores themselves have all imposed restrictions on GM foods. Manufacturers must label all foods that might have genetically altered ingredients. This includes food with genetically manufactured organisms, food with an intentionally modified molecular structure, and food that has been isolated for microorganisms, fungi, and algae. Furthermore, the genetically altered food must not mislead the consumer, present any danger to the consumer, or differ from the food that it is intended to replace so that the altered food is a nutritional disadvantage to the consumer (Tackling Food Safety Concerns over GMO’s, Development of meth ods to identify foods produced by means of genetic engineering). This legislation has now created trade barriers for food coming into Europe – some imported food is genetically modified and creates a risk to the people’s health and safety. Nevertheless, because some supermarkets in Europe have decided to be non-GM only, this has created a competitive disadvantage for the â€Å"half†-GM supermarkets. This response to consumer pressure is also having an effect on some companies or countries that cannot meet the legislative needs, and are obliged to lose markets and/or market shares (Tackling Food Safety Concerns over GMO’s, European network safety assessment of genetically modified food crops). If the world finally agrees to the consumption of GM food, European countries will be the last to â€Å"give-in† to the more lenient regulations. If one is to ask a North American if the product he or she is eating contains GM food, he or she will most likely show a blank stare. This is because regulation of GM food in North America is relatively relaxed when compared to Europe (Borger, second paragraph). Since the manufacturer is not required to label their products, the consumer is oblivious to buying GM food at the supermarket. Agriculture and technology are both being heavily invested in the United States. Profit is an important driving force for the developed world, and agricultural exports make up a large portion of exports from the United States (Borger, third paragraph). Since the demand for food is always increasing, the demand to produce more food at a faster rate requires the need for better biotechnology to be put into practice. And because of the lax laws in effect for the United States, and Canada, North Americans are â€Å"in the dark† with regards to what they are eating during their meals. North Americans are not educated about the risks of GM food, nor are they aware of where to find information regarding how much GM food is in their groceries (Borger, 12th paragraph). This poses a serious threat to the potential health of North Americans, as they are nothing but â€Å"lab rats† waiting for their first abnormal â€Å"twitch†. Human health can be seen as the greatest factor when considering the manufacturing of GM food. This is because of the few diseases and viruses that have been discovered which formed through the use of GM food. Also, the potential for new diseases and/or viruses through the use of GM food is increasing, and people are not aware of the risks. Antibiotics or pesticides have not yet been created to combat the superbug, and this is a concern for humans, as it will infect people, and crops altogether. There is a potential for the biodiversity to decrease because of gene transfers from one species to another, creating more powerful crops, which may take over the natural populations of weeds and grasslands. An additional way for the biodiversity to decrease is by farmers planting only a single variety of crop, thus wiping out the varied species needed to keep the diversity within crop fields. Europeans are the most aware of GM food, and are taking the necessary precautions and legislative actions to protect themselves against the use of GM food. However, North Americans are the least aware of GM food, and their government has not yet educated their citizens on the risks of GM food. There are too many risks involved in the use of GM food, and its removal from the agricultural and biotechnological industries will benefit human health, the environment, and global economy.

The History Of Education In Malaysia

The History Of Education In Malaysia According to Oxford Dictionaries, philosophy is the study of the fundamental nature of knowledge, reality, and existence, especially when considered as an academic discipline. The term philosophy is derived from two Greek words that are philosophia, which consist of the root phileo and Sophia. The meaning of phileo is to love and sophia means wisdom. It is very important for Malaysia which is a developing country to have its own philosophy of education. Therefore, National Philosophy of Education (NPE) has been enacted in 1998 based on basis documents and national ideology. From a historical perspective, NPE born from a long process which is a nation building process since the independence of Malaysia. Education in Malaysia is an on-going effort towards further developing the potential of individuals in a holistic and integrated manner, so as to produce individuals who are intellectually, spiritually, emotionally and physically balanced and harmonic, based on a firm belief in and devotion to god. Such an effort is designed to produce Malaysian citizens who are knowledgeable and competent, who possess high moral standards and who are responsible and capable of achieving a high level of personal well-being as well as being able to contribute to the harmony and betterment of the family, the society and the nation at large. According to the NPE, there are eight elements of national philosophy of education. Firstly, education is an on-going effort which brings the meaning of education emphasis on life-long learning. Life-long learning is needed because individuals knowledge is ever-changing as there is no absolute knowledge of each individual. It is important for individuals to adapt to the change of times and new development such as Information and Communication Technology (ICT), economy and other current issues. Life-long learning encourages individuals to develop their personal skills and knowledge. Secondly, holistic and integrated manner is the universal body of knowledge which must be taught by the teachers and learnt by the students. It is important to develop the individuals potential and abilities in a holistic and integrated manner. This is because talents, potentials and abilities do not develop separately as they are related and co-ordinated and do not compete with each other. The development of the individual and their improvement should properly include the four aspects which are physical, emotional, spiritual and intellectual. Besides, firm belief and devotion to God is a must for individuals regardless what their religion is. It is an element of the existence and role of the religion. b) CURRICULUM According to the Ministry of Education, in the Malaysian context, curriculum means all programs that were carried out by a school or educational institution to achieve the target of education. Curriculum is a well-organized plan that includes academic and non-academic activities which include the educational objectives, the experience of planned and the evaluation of student achievement. It is a plan that covers all the knowledge, skill, values and norms of cultural elements and beliefs of the society to be transferred to their inheritance. Curriculum can be divided into three which are curriculum as a programme that has been planned and implemented in schools, curriculum as a programme designed and practically implemented in the classroom and curriculum is filling of a culture of life-long learning and individual and group experience. The main components in a curriculum are the contents of the curriculum, the objectives of the curriculum, the learning and teaching activities and the assessment process of curriculum. Teachers play an important role in the implementation of the curriculum that includes interpreting, plan, modify and implement the curriculum. c) SUBJECTS Malaysia has undergone three curriculums of primary education so far since the country got the independence. The three concepts of primary education are Old Primary School Curriculum (KLSR), New Primary School Curriculum or Integrated Primary School Curriculum (KBSR) and Standard Primary School Curriculum (KSSR). Old Primary School Curriculum (KLSR) was the first curriculum that has been used and was implemented during 1960. It was the first phase of the implementation of the plan that has been enacted in the education system in the Education Act 1961. In this phase, the educational system was oriented to eliminate the literacy among students. The assessment was the important aspect in KLSR so it has many types of assessment such as Ujian Lisan Bahasa Melayu (LCE) which then has been removed and replaced by Sijil Rendah Pelajaran (SRP) on 1978, Ujian Diagnostik Darjah Tiga and Assessment Test Standard Five. However, it had lots of weaknesses such as the content of its syllabus had repetition and was not related to each other so it was hard to be implemented well. Besides, the syllabus was too much and made students bored in the classroom. The co-curriculum activity was also separated and was not related to the formal curriculum in the classroom. This concept was abolished since there were too many feedbacks that wanted the curriculum to be changed. The new curriculum was New Primary School Curriculum (KBSR) which has been introduced in 1982 after the Cabinet Committees Report made a change on the Implementation of Education Policy. KBSR was fully implemented in 1983 and the name was changed to Integrated Primary School Curriculum (KBSR) on 1993. Even the name was changed but its content was still the same. Its curriculum written was based on learning outcomes. KBSR had its objectives which students master the Bahasa Melayu at satisfactory level besides stress on 3Rs basic skills that were reading, writing and arithmetic. KBSRs curriculum design was based on three areas and its materials were study syllabus. Its principles were integrated approach, one education for all, life-long learning and holistic development of individual. An examination that has been carried out was the National Examination (UPSR). Unfortunately, it had its cons although it had brought positive changes in Malaysias education. A few of KBSR principles had not implemented well in the teaching and learning process because it has been focused more on achieving grade As in the examination. So, the objective to develop excellent individuals was not achieved as they were not learning to gain more knowledge, experiences and skills but learnt to prepare for the examination only. Phase I, Malay Language, English Language, Chinese Language, Tamil Language, Mathematics, Islamic Education, Moral Education, Music Education, Art Education and Physical and Health Education Phase 2-Malay Language, English Language, Chinese Language, Tamil Language, Islamic Education, Moral Education, Science, Local Studies, Living Skills, Music Education, Art Education and Physical and Health Education The concept of KBSR has been replaced by Standard Primary School Curriculum (KSSR) that was implemented in 2011. In KBSR, it focussed on 3Rs but KSSR focussed on 4Rs basic skills which reasoning was being add-on. However, KSSR still acquired basic skills in every student same as in KBSR which also practiced the moral values. Its curriculum written was a little bit different from KBSR which it was based on content and learning standards. KSSRs curriculum materials were curriculum standard documents and its design was based on six areas as communication was still being carried out. It evaluates students by National examination (UPSR) and school-based assessment. A basic core modules that are taught in KSSR for phase 1 are Malay Language, English Language, Chinese Language, Tamil Language, Mathematics, Islamic Education, Moral Education and Physical and Health Education. The core module themes are Visual Art and Music, Science and Technology World and Malaysia Negaraku. The elective modules for this phase are Chinese or Tamil Language for Primary School, Arabic and Iban Language. In phase 2 there are respective modules that categorized each subject. The modules are communicated; elective communication; spiritual attitude and values; physics and aesthetics; science and technology; and humanity. Subjects for each module are Malay Language, English Language, Chinese Language and Tamil Language; Chinese or Tamil Language for Primary School, Arabic, Iban, Semai or Kadazandusun Language; Islamic and Moral Education; Physical and Health Education, Music or Visual Arts Education; Mathematics, Science and Design and Technology; and History or Malaysia Negaraku. Before a new concept is implemented, a trial will be conducted for a given period until there is a command to run the concept or else, the trial will be stopped if it is not suitable to students need. In conclusion, the curriculum will always change over time. There is no wrong to make a difference or change because change for the better is well recommended. As it will change with time, it will always be improved for students to have a better education in order to form a good community besides gives advantages to the country. d) ROLE OF NPE AND CURRICULUM TO SCHOOL e) ROLE OF NPE AND CURRICULUM TO TEACHERS f) ROLE OF NPE AND CURRICULUM TO STUDENTS ACTIVITIES IN SCHOOL Teachers Day Celebration Teachers Day is celebrated on 16th of May every year as a sign to appreciate the teachers contributions in developing the human capital that is essential in the construction of society. Teachers are also known as social architects because they are not only providing education and imparting knowledge but they are also serving to realize the transformation of education based on the NPE. There are six objectives of the celebration of teachers day in Malaysia that are emphasizing the role of teachers in nation building including unity and integration, national development and community service. Besides, it is celebrated to attract the attention of parents, students and the public on the important role of teachers in the Malaysian society and fostering a sense of professional cohesion and goodwill among the teachers. Teachers day celebration can raise the prestige and status of teachers in the community. It is also to provide opportunities for teachers to develop competencies through semi nars and conferences held on Teachers Day. Objectively assess the role of a teacher with a backdrop of Malaysia and to take steps so that more effective role. The celebration of teachers day is organized by the teachers charity organization. The day began with an official assembly filled with programme such as sing the National Anthem Song, the State Song, the school Song and Guru Malaysia Song. Besides, the headmaster will read special deputations from the Prime Minister and the Minister of Education which the texts are related to the theme of the Teachers Day Celebration. Every year, the theme of the Teachers Day Celebration will be changed. A variety of exciting events have been organized by the school after the assembly in order to enliven the celebration and enhance the friendly feeling among teachers and teachers, teachers and students also students and students. Sports Day The growth of outstanding child is formed from a combination of intellectual, physical, spiritual, emotional and social potential as it is contained in the National Philosophy of Education. Hence, for the development of a balanced human being, then the school will hold a sports day to lead to the formation of the balanced human being. It is implemented with the parents collaboration to strengthen the social relationship with the community. The goals of the Sports Day is to produce excellent students who are balanced in terms of physical, emotional, spiritual, intellectual and social development in line with the NPE. Furthermore, the objectives are to fulfil the students need in sports and recreation, to produce individuals who always compete others in good ways and to foster the spirit of cooperation and working together as a team. In addition, Sports Day is to find the students talents in sports to higher levels and choose students to represent the school to the MSSD Championship. T he sports day will be on February or March and two events will be held that are field events and track events. There are three field events that are high jump for students under 12 and under 10, broad jump for students under 12, shot put for boys and girls students under 12 and 10 with the same weight that is 2.72 kg. The track events are 80 m and 200 m for boys under 12, 80 m for boys under 10, for girls under 12 the track will be 80 m and 200 m while girls under 10 will be 80 m only. There are also 80 m hurdles for students under 12, 2000 m walk for boys and girls under 12, 4100 m and 4200 m for students under 12 and 50 m relay for students under 12. Before the sports day, a selection day will be held to choose the best students among the rest to represent their team. The State of Education Department will provide an allocation to conduct the sports day. Independence Day The Independence Day of Malaysia was on 31st of August 1957 and we as Malaysian will celebrate the day every year as it is a public holiday on that day. The programme also is celebrating in school to inspire the spirit of independence in teachers as well as in students in order to recognize the importance of Independence Day celebrations. Engender a sense of pride and love for the nation and put self-interest above national interest among the school is one of the objectives of the celebration. Secondly, produce schools community that is responsible as citizens of Malaysia to maintain independence, adopted a patriotic behaviour and proud toward the countrys independence. Lastly, Independence Day can create a sense of unity and lasting peace and continuous among the school from different races, religions and customs. The Independence Day began with an assembly filled with programme such as sing the National Anthem Song and Independence Song such as, Tanggal 31, Anak Malaysia and Jalur Gemilang. In addition, there will be a film showing on an independence movie that is Leftenan Adnan and a slide show on the history of the Independence Day of Malaysia by using a projector in a hall. The figures of the Independence Day will be called to share their experiences during the colonial period. Furthermore, there will be performances from students and the performances must be about the Independence Day. Language Month Language Month that organized by the Malay Language subject panels was held in school to feature students talent especially at school level, region, district, state and national level. This could indirectly produce students who are brave and confident with their own abilities. Hopefully with the availability of this month, the students will understand and love the Malay Language as it is an important language and should be learned in depth. Language months objectives are to provide an opportunity for students to express their talents and to be featured to higher level. Besides, it is to test the students understanding of their knowledge related to Malay Language, to encourage them to compete in a good way to get the best place, particularly in relation to language and to produce students who are competent in the field of language. There are many competitions that will be held during this month such as story telling competition that all students can taking part in it, poetry competiti on for students above 10 and essay writing competition also for students above 10 and there will be prizes for the winners. Co-curriculum Day Co-curriculum Day is a must event in most of schools in Malaysia and no date adjusted for every school by the department hence, schools can freely choose their date to organize this programme. The goal of the Co-Curriculum Day is intended to achieve some goal which is growing nature work together, compromise, and the bond of unity among students and teachers, produce potential future leaders among pupils and to improve the school environment more exciting and cheer the students in order to produce a superior school culture. Co-Curriculum Day objective is to encourage students active and interested in co-curricular activities organized by the school or a particular party. Among them are fostering unity works in a group association, club or uniform units, to produce students of the utmost caliber and dedication and ability to be a caliber leader. Last but not least, to encourage pupils to work in the aspect of leadership can foster an attitude and discipline. Among the activities that will be held are sales booths, books exhibition, national anti-drug exhibition, marching by uniform units and telematches. ACTIVITIES IN CLASSROOM I have made an interview with a teacher from SK Putrajaya Presint 9(2) about the way she handle students in the classroom. Based on the interview and my experience, students find hands-on activities are more exciting than lecture-based style learning and they tend to focus more on that. Quiz Quiz is a test of knowledge, especially as a competition between individuals or teams as a form of entertainment or asks someone questions according to the Oxford Dictionary. Classroom quiz shows can be beneficial to students for many reasons. Short quiz at the beginning of each class is usually preferred by teachers in their classroom. Short quiz is beneficial for students for many reasons because it helps students to focus and develop their essential problem-solving skills as certain lecture. It is not just a quiz because it is also an emergency motivation for students. It is a very effective motivation as it can increase the students effort and their learning outcomes as well as for those who have low motivation and have high intelligence. Discussion The action or process of talking about something in order to reach a decision or to exchange ideas is the definition of discussion based on Oxford Dictionary.

I am The Universe Essay -- Character Analysis, Moby Dick, Ahab

Everyone is responsible for their own actions. Moreover, Fate is just a scapegoat if something goes wrong. Captain Ahab, a character in the novel Moby Dick by Herman Melville, is a victim of his own negligent actions. As a result, he faces an unfortunate death from the fury of the white whale. Ahab places all of his hate on the whale, whom is later referred to as Moby Dick, because he lost a leg to him. He thinks that Moby Dick represents all of the hatred and evil in the world, and that he must go and destroy it. Yet, he is fully responsible for his own death due to the fact that he overlooked the warning signs that Nature and God provided for him, lacked communication between him and his shipmates, and preferred to be isolated from the crew in order to fuel his monomaniac conscience to put Moby Dick to his death. Because Ahab is the captain of the ship, he assumed that he ultimately had higher authority than God. God, in his mind, was in the wrong, by letting Moby Dick â€Å"dismember† (Melville 161) him; leading into Captain Ahab’s growing fixation with the beast. While being infatuated with Moby Dick, he is forced to ignore the obvious signs from Nature that were telling him to change his plans if he desired to live. However, Ahab chose to ignore the warning signs that were thrown at him throughout the novel. One omen that Ahab chose to pay no heed to was when the Pequod â€Å"was left to fight a Typhoon which had struck [it] directly ahead† (482). The result of that typhoon was that the ship changed directions, heading West rather than East. Ahab realized this when he â€Å"turned to eye the bright sun’s rays† and claimed that â€Å"[he’ll] be taken now for the sea-chariot of the sun† (495), meaning that the Pequod was pulling the sun along wi... ...e and child, too, are Starbuck’s† (521). Ahab refuses to turn the ship around since his â€Å"glance was averted; like a blighted fruit tree he shook, and cast his last, cindered apple to the soil† (521). Therefore, Ahab ultimately deserves his death since he has brought it upon himself. Ahab had been killed by hemp, referred to through Fedallah’s prophecy. The death was well deserved to the monomaniac captain whose heresy conquered the humanity in him through his own freewill. By bolstering about his immortality on land and on sea, Ahab had fueled the idea that he was a superb being. He had shielded his eyes from every sign that Nature and God bestowed upon his sight, failed to effectively communicate with his shipmates and crew, and continuously isolated himself in his quarters throughout the journey. Through Ahab’s poor actions, he was responsible for his demise.

The Function of the Music in Porgy Essay -- Porgy Music Musical essays

Music has a way of bringing out our emotions. We say that there are moods of music, and we know which songs make us happy and which make us sad. But music also connects with us intellectually through the lyrics and what we understand them to mean. Thus, music becomes a way to link aspects of intellectual and emotional life – to combine thought and feeling. In the novel Porgy, we see music used as a tool to do just that; music, whether sung, imitated, or described metaphorically, is used, among other things, to link mental and emotional states. One way music serves as a link is by tying the emotions of the reader to the situation and state of mind of the characters or community. The first instance of this is when the community is mourning the death of Robbins. The music starts with a crude call and response cry. â€Å"What’s the matter, chillen?† came the strophe. And the antistrophe swelled to the answer: â€Å"Pain gots de body, an’ I can’t stan’ still.†... â€Å"What de matter, Sister?† â€Å"Jedus gots our brudder, an’ I can’t stand still.† Ever since Porgy had come home the air had swung to the rhythm of the chant...The burden swayed out again. â€Å"Pain gots de body, an’ I can’t stan’ still.† (15) The words of the call and response describe the situation the community is in – it has lost one of its members and the others feel the pain of loss – but what really allows the reader to feel pain with the community is the chant itself. By putting the words in the form of a chant, the author has given them authority and made them personal to the characters singing them. Through his description of air swinging to the rhythm and of the swaying burden (which has a connotation much different from that of â€Å"refrain†), Heyward creates an image of ... ...ame. â€Å"‘Little w’te babies,’ he crooned, ‘come sing fuh dis nigger.’ He cast – and won† (60). When Porgy says â€Å"come sing,† Heyward is showing us that the music has affected him. The fact that he won shows that the effect was genuine and not imagined. In Porgy, one function of music is to tie together emotional and intellectual states. At some points, music allows the intellect of the reader to be engaged with the emotions of the characters (or vice versa); at some points, music causes the intellect of characters to give in to their emotions; at some points, it encourages them to elevate their mood either by finding external reasons to be happy or simply though cohesiveness within a community. The use of music allows for a deeper understanding of the characters, what they are going through, why they act the way they do, and what it means to be part of a community.

And the antistrophe swelled to the answer: â€Å"Pain gots de body, an’ I can’t stan’ still.†... â€Å"What de matter, Sister?† â€Å"Jedus gots our brudder, an’ I can’t stand still.† Ever since Porgy had come home the air had swung to the rhythm of the chant...The burden swayed out again. â€Å"Pain gots de body, an’ I can’t stan’ still.† (15) The words of the call and response describe the situation the community is in – it has lost one of its members and the others feel the pain of loss – but what really allows the reader to feel pain with the community is the chant itself. By putting the words in the form of a chant, the author has given them authority and made them personal to the characters singing them. Through his description of air swinging to the rhythm and of the swaying burden (which has a connotation much different from that of â€Å"refrain†), Heyward creates an image of ... ...ame. â€Å"‘Little w’te babies,’ he crooned, ‘come sing fuh dis nigger.’ He cast – and won† (60). When Porgy says â€Å"come sing,† Heyward is showing us that the music has affected him. The fact that he won shows that the effect was genuine and not imagined. In Porgy, one function of music is to tie together emotional and intellectual states. At some points, music allows the intellect of the reader to be engaged with the emotions of the characters (or vice versa); at some points, music causes the intellect of characters to give in to their emotions; at some points, it encourages them to elevate their mood either by finding external reasons to be happy or simply though cohesiveness within a community. The use of music allows for a deeper understanding of the characters, what they are going through, why they act the way they do, and what it means to be part of a community.

Investigating the changing effects of temperature

Investigating the effects of changing temperature on the activity of enzymes Background information: Renin is an enzyme that catalyses the coagulation of milk. It is found in the stomach of many animals and is used in making cheeses and Junkets. It is found in the gastric juices or gastric mucosa of many mammals, including humans. In the human stomach, particularly those of infants, rennin works to curdle milk so that pepsin, another stomach enzyme, can further breakdown the proteins into absorbable amino acids called polypeptides.The aim of this experiment is to investigate the effect of changing temperature on the activity of enzymes. After experimentation the optimum temperature for enzyme activity will be established and the effects of varing temperature will be identified. Several experiments have already been conducted testing similar hypothesis and aims. All of these experiments also had very similar results. They found that approximately 370C was the optimal temperature for r ennin; it was at this temperature that the milk solidified quickest.Below that the reaction would occur far more slowly, sometime taking hours to complete, sometimes not reacting at all. Above 370C, at approximately 450C, the enzyme would become enatured and the reaction would never occur, even after the temperature was lowered back down to 370C. 1 Aim: To investigate the reaction rate of the enzyme rennin at various temperatures Hypothesis: It is predicted that a rise in temperature (to approximately 400C) will increase enzyme activity.Wth further increase of temperature the protein enzymes will denature, lose their shape and therefore decrease in activity. Risk assessment: Risk Precaution Burns from the hot water bath or hot plate Ensure that all hot baths are set up in a visible area that is surrounded by minimal movement. If burns occur run affected area under cold water for 5-10 minutes depending on severity. Major burns should seek medical assistance Glass breakage can cause c uts/wounds Use test tube rack to steady test tubes.If glass breakage occurs immediately alert teacher, sweep up broken glass using a broom or dust pan and dispose of it in the appropriate bin Apparatus: Equipment Rationale 1 hot plate Heats water in hot bath for raising temperatures of milk and rennin above 300C 1 hot bath holds water which is heated by not plate 1 ice bath (500mL beaker + 6-7 ice cubes) Cools milk and rennin for testing temperatures below 300C regular test tubes Holds the 20mLs of milk required for each trial 3 micro test tubes Holds the small amount of rennin required 1 test tube rack Holds regular sized test tubes in place so handling does not influence reaction 20mL of milk Acts as substrate 2mL of rennin solution Acts as enzyme for milk 1 large pipette Gives precise measurment of milk 1 syringe Gives precise measurement of rennin 2 thermometers Measures temperature of milk and rennin when they are heated or cooled 1 timer Measures time taken for milk to set Met hod: Constant Variables Factor Importance Method of control Volume of milk The amount of milk determines the amount of substrate the enzyme has to work on which therefore effects the reaction rate. Keeping a constant amount of milk for each trial. Use Pipette Volume of rennin The amount of enzymes determines the amount of chemical reactions possible to occur. Keeping a constant amount of enzymes for each trial- Iml per every 10ml of substrate. Use a syringe Rennin and milk brought to the same testing temperature Temperatures must be constant for both substances to ensure accuracy when they are mixed.Place each substance in a hot or cold water bath with thermometers in their test tubes. Remove from water bath when the same temperature has been reached Same time recorder Timing must be accurate. With the same person reaction rate to press go and stop would be similar for each trial. Have the same time recorder for every trial possible Same setting standard A setting standard must be d etermined to make timing of reaction rate accurate. Make a class decision on what is classified as set Standerdized thermometers To ensure accurate temperature readings Ensure all thermometers are standardized before experimentation Type of milk- from the same container Different types of milk may influence enzyme activityUse the same milk for each trial Type of Junket- from the same container Different types of rennin may influence enzyme activity Use the same rennin for each trial Whether the solutions should be stirred or not A stirred or shaken solution may speed up reaction rate because more enzyme collisions would occur and faster Make a class decision on whether to shake/stir mixture or keep it still 1 . Measure 20mls of milk using the pippette and release it into a regular test tube 2. Measure 2mls of rennin using the syringe and release it into a micro test tube 3. Place thermometers in both test tubes ensuring that the rennin does not overflow 4. Fill a 500ml beaker with 2 50ml of water and 6-7 ice cubes 5. Place both test tubes in the ice bath 6.Watch both thermometers until they reach OOC 7. Pour the rennin solution into the test tube of milk. Begin timing as soon as all the rennin is poured into the milk 8. Shake the test tube slighlty to mix the rennin and milk together 9. Stop the timer once precipitate has formed or the milk has completely solidified 10. Repeat steps 1-9 using various other temperatures Note: use a hot plate and hot water bath when testing temperatures above 300C Results: Temperature ( C) Average time taken for milk to set (min) No reaction – did not set 10 5min + 20 4:42 4:37 1. 29 50 1. 48 70 Discussion: When temperatures were either very low or very high enzyme activity did not occur or was minimal.This is because cooler temperatures decrease the amount of kinetic energy within the enzyme molecules. If there is not a substantial amount of kinetic energy, enzyme molecules are unable to collide with their substrate which therefore prevents reaction from occurring. Because enzymes are proteins when temperatures were too high the enzymes denatured, lost their structure and shape, making their active sites no longer complementary to their substrate's. At temperatures around 40-50C enzyme activity rapidly increased and the milk set under two minutes. This temperature range is therefore the optimum temperature for enzyme activity because enzymes obtain substantial amounts of kinetic energy and do not become denatured.Accuracy was not constant throughout the experiment as small amounts of rennin were lost everytime a thermometer was placed in the micro test tube. Some milk was also lost when the rennin was added to it and the test tube was shaken. This may have affected the reaction rate of the enzymes. It was very difficult to calculate the exact temperature t which the enzyme and substrate were mixed because their temperatures dropped or rose rapidly when they were removed from the hot or cold baths. T his further affected the accuracy of the experiment as temperatures tested were not exact. Repeated trials of the same temperature all had similar results which made the averages precise.There were no outliers so averages were not too high or too low. If an outlier occurred during experimentation because of known reasons the trial was tested again. Each temperature was tested three times making the experiment reasonably reliable however different groups tested each temperature which may ave affected the reaction times recorded because of different perceptions about setting points and the speed of the persons timing. The limitations of this experiment were therefore caused by human error To prevent errors during experimentation more caution should have been taken when: mixing and shaking substances, recording the reaction rate, interpretation of setting time and the handling of test tubes.When shaking and handling the test tubes a stopper should have been used to prevent loss of mixt ure and exposure of heat from the person's hands. Timing should have been conducted by the same person for every trial however this would ave taken far too long. Interpretation of setting time should have been clearly explained or demonstrated before conducting the experiment. The results of this experiment correlated closely to research undertaken about the effects of changing temperature on enzymes. This therefore made the practical more valid and reliable. Most constant variables were followed and monitored precisely which further added to the fairness of experimentation.A few constant variables that may have been affected by human error were the temperatures at which the substances were brought to, the volume of rennin and the perceptions of the milks setting point, lthough the same instructions were given to all students . Conclusion: Enzyme activity therfore increases as temperatures increase to their optimum temperature (37-450C). Once temperatures exceed the optimum temperat ure the enzymes denature (lose their shape) and become inactive.
