Nora Helmer of A Dolls House, a Play by Henrik Ibsen

Nora Helmer of 'A Doll's House,' a Play by Henrik Ibsen One of the most complex characters of 19th-century drama, Nora Helmer prances about in the first act, behaves desperately in the second, and gains a stark sense of reality during the finale of Henrik Ibsens  A Dolls House. In the beginning, Nora exhibits many childish qualities. The audience first sees her when she returns from a seemingly extravagant Christmas shopping excursion. She eats a few desserts which she has secretly purchased. When her condescending husband, Torvald Helmer, asks if she has been sneaking macaroons, she denies it wholeheartedly. With this minor act of deception, the audience learns that Nora is quite capable of lying. She is most child-like when she interacts with her husband. She behaves playfully yet obediently in his presence, always coaxing favors from him instead of communicating as equals. Torvald gently chides Nora throughout the play, and Nora good-naturedly responds to his critics as though she were some loyal pet. Nora Helmers Clever Side However, Nora has been leading a double life. She has not been thoughtlessly spending their money. Rather, she has been scrimping and saving to pay off a secret debt. Years ago, when her husband became ill, Nora forged her fathers signature to receive a loan to save Torvalds life. The fact that she never told Torvald about this arrangement reveals several aspects of her character. For one, the audience no longer sees Nora as the sheltered, care-free wife of an attorney. She knows what it means to struggle and take risks. In addition, the act of concealing the ill-gotten loan signifies Noras independent streak. She is proud of the sacrifice she has made. Although she says nothing to Torvald, she brags about her actions with her old friend, Mrs. Linde, the first chance she gets.  Basically, she believes that her husband would undergo just as many hardships, if not more, for her sake. However, her perception of her husbands devotion is quite misplaced. Desperation Sets In When the disgruntled Nils Krogstad threatens to reveal the truth about her forgery, Nora realizes that she has potentially scandalized Torvald Helmers good name. She begins to question her own morality, something she has never done before. Did she do something wrong? Were her actions appropriate, under the circumstances? Will the courts convict her? Is she an improper wife? Is she a terrible mother? Nora contemplates suicide in order to eliminate the dishonor she has wrought upon her family. She also hopes to prevent Torvald from sacrificing himself and going to prison in order to save her from persecution. Yet, it remains debatable as to whether or not she would truly follow through and jump into the icy river. Krogstad doubts her ability. Also, during the climactic scene in Act Three, Nora seems to stall before running out into the night to end her life. Torvald stops her all too easily, perhaps because she knows that, deep down, she wants to be saved. Nora Helmers Transformation Noras epiphany occurs when the truth is finally revealed. As Torvald unleashes his disgust towards Nora and her crime of forgery, the protagonist realizes that her husband is a very different person than she once believed. Torvald has no intention of taking the blame for Noras crime. She thought for certain that he would selflessly give up everything for her. When he fails to do this, she accepts the fact that their marriage has been an illusion. Their false devotion has been merely playacting. She has been his child-wife and his doll. The monologue in which she calmly confronts Torvald serves as one of Ibsens finest literary moments. The Controversial Ending of A Dolls House Since the premiere of Ibsens A Dolls House, much has been discussed regarding the final controversial scene. Why does Nora leave not only Torvald but her children as well? Many critics and theater-goers questioned the morality of the plays resolution. In fact, some productions in Germany refused to produce the original ending. Ibsen acquiesced and grudgingly wrote an alternate ending in which Nora breaks down and cries, deciding to stay, but only for her childrens sake. Some argue that Nora leaves her home purely because she is selfish. She does not want to forgive Torvald. She would rather start another life than try to fix her existing one. Or perhaps she feels that Torvald was right, that she is a child who knows nothing of the world. Since she knows so little about herself or society, she feels that she is an inadequate mother and wife. She leaves the children because she feels it is for their benefit, painful as it may be to her. Nora Helmers last words are hopeful, yet her final action is less optimistic. She leaves Torvald explaining that there is a slight chance they could become man and wife once again, but only if a Miracle of miracles occurred. This gives Torvald a brief ray of hope. However, just as he repeats Noras notion of miracles, his wife exits and slams the door, symbolizing the finality of their relationship.

To Curry Favor

To Curry Favor To Curry Favor To Curry Favor By Maeve Maddox A reader asks, Does the expression Curry Favour have anything to do with curry? Short answer: â€Å"No.† But the long answer is pretty cool. The gastronomical word curry derives from a Tamil word for sauce, whereas, the curry in the expression â€Å"to curry favour/favor† is a verb meaning â€Å"to comb a horse.† curry (noun): A preparation of meat, fish, fruit, or vegetables, cooked with a quantity of bruised spices and turmeric, and used as a relish or flavoring, especially for dishes composed of or served with rice. Hence, a curry = a dish or stew (of rice, meat, etc.) flavored with this preparation (or with curry-powder). curry (verb): to rub down a horse with a comb. The word favor in â€Å"to curry favor† is the product of folk etymology. The original expression was â€Å"to curry Favel,† in which Favel is the name of a fictional horse. Satirical allegories featuring anthropomorphized animals were popular in the Middle Ages. The name Favel came into English from the French tale Le Roman de Fauvel, in which a horse named Fauvel parodied the hypocritical behavior of the courtiers and ecclesiastical lords of the French royal court. The horse’s name derives from his color: he’s a â€Å"fallow horse.† As an adjective, fallow refers to a pale brownish or reddish yellow color. It’s probably cognate with Latin pallere, â€Å"to be pale.† Both English and German had an idiom that may have preceded the French tale: â€Å"to ride the fallow horse.† The expression meant, â€Å"to practice duplicity.† One academic theory as to why riding a fallow horse was associated with hypocrisy is that the expression may have originated with â€Å"the pale horse† in the Apocalypse (Book of Revelation). The rider of the pale horse, â€Å"one whose name is Death,† was thought by some commentators to represent the duplicitous Antichrist. When the word Favel became meaningless to English speakers, they substituted it with the familiar word favor. In sum, to curry chicken is to cook it with curry. To curry favor is to seek to gain an advantage by means of flattery and hypocrisy. Here are some recent examples of the use of curry in the nonfood sense: Leadership PACs generally attempt to curry favor with other lawmakers, hoping to win support for legislation or other political aspirations. If we change [the law], Mr. Lynn said, were going to see politicians running around seeking support of churches and hoping that they can curry favor with those churches by promising them money and favors. Not only did he flout those laws in order to curry favor with a prospective employer, but he also illegally disclosed the identity of a whistleblower, as the Complaint alleges. The lobbying campaign, reconstructed by  Newsweek  and The Daily Beast through interviews and documents, speaks volumes about the efforts of big business to curry favor, even among perceived enemies.   Curry may also be followed by approval and good will: Jorge is explaining to his men that Nikita Khrushchev has permitted a few chosen writers to travel abroad,  hoping to curry approval  from the worlds cultural elite. Kuwait used its resources to  curry good will  among Arab countries, especially Egypt. Want to improve your English in five minutes a day?

Intellectual Disability (Formerly Mental Retardation) Research Paper

Intellectual Disability (Formerly Mental Retardation) - Research Paper Example These are genetic, acquired, environmental and sociocultural. In genetic factors, it involves chromosomal or hereditary disorders. Due to the translocation of chromosomes 21 and 15, which cause Down syndrome in newborns, which statistics show occur in 15 of every 10000 births. Other related intellectual disabilities caused by chromosome disorder are the fragile X chromosome syndrome, lesch-nyhan syndrome and rett syndrome among others. On the other hand, intellectual disabilities are acquired through hereditary factors. It can be passed from a parent to a baby. These hereditary factors include galactosemy, Tay-Sachs disease, phenylketonuria, Mowat-Wilson syndrome among others (American Psychiatric Association, 2000; Fernald, 1912). There are acquired factors that also cause intellectual disabilities and these can be grouped into two groups: Congenital and developmental factors. Congenital factors are those that acquired through the infected parent’s body. These infections can be through metabolic, neonatal hypothyroidism, intoxication through lead poisoning, fatal syndrome or prenatal exposure to lethal substances and infectious body diseases like syphilis, toxoplasmosis among others. On the other hand, developmental factors include those infections that are acquired during prenatal period where pregnancy complications such as toxemia could arise leading to intellectual disability (Schrander-Stumpel, et al, 2007). ... Poverty opens up a wide exposure to environmental and psychosocial factors to the infants. Poor prenatal, perinatal and postnatal health care can lead to intellectual disabilities as well. The above factors are just a few of the known causes of intellectual disabilities though to date, most causes are still unknown and still being researched (American Psychiatric Association, 2000; Schrander-Stumpel, et al, 2007). With different intellectual disabilities, the symptoms differ from one disability to the other with most common characterized by limitation in communication, personal care, home life, self-governance, leisure time, work, academic skills, health and safety and lastly limitations in social life (Schrander-Stumpel, et al, 2007). While these are common characteristics, there are those particular characters that are observed with a particular disability. With the genetic disorders in the fragile X syndrome, a person’s brain is affected, hence, displaying characters associ ated with autism, which include poor eye contact, anxiety, sudden mood change and hand flapping (American Psychiatric Association, 2000). Although it is rare, it affects both males and females. In the case of Phenylketonuria, it leads to corrosion of myelin in the brain exhibiting signs of epilepsy and neurological problems. There are symptoms of autistic disorder and hyperactivity in the case of Bourneville as an intellectual disability. Lastly, on genetic etiology, there is Lesch Nyhan syndrome, which allows excess flow of uric acid. It is characterized by self-mutilating behaviors like finger, lip biting, and makes the victim more aggressive towards others (American Psychiatric

Marketing Strategy of Atlas Travel Club Coursework

Marketing Strategy of Atlas Travel Club - Coursework Example The Atlas Travel Club, an incoming tour operator based in London, will be used as a case study in order to meet the objectives of the study: to determine markets, to discover the rational for choosing a marketing strategy, what factors influence marketing strategies, and how to determine the effectiveness of marketing strategies. This study also seeks to prove the hypothesis that "By getting to know the culture, norms, values, and business practices of the emerging market, a company can develop a unique marketing strategy which will help it achieve its goals." Findings indicated that the marketing strategy of Atlas Travel Club is extremely successful. A concluding recommendation was that more time be given for the interviews in order to gather more answers. Respondents should include customers and potential customers. Questionnaires should also be used as they are a good way to avoid "interview effects" whereby an interviewer influences or affects the participant's responses by their presence or method of questioning; something particularly problematic when interviewing members of a corporation who do not want to say anything negative in regards to the company for various reasons. In contrast self-completion questionnaires can be filled out independently of the researcher. It is important that both interviews and questionnaires be employed because disadvantages of using a questionnaire include the lack of an interviewer means interesting responses cannot be followed up and the respondent cannot add their own remarks. Similarly it may not be possible to correctly judge the participant's potential response, and therefore categories may not be exhaustive. It is also recommended that interviews and questionnaires present more questions regarding complaints and negative feedback. It is typical that these questions are limited in order not to get negative answers. Feedback, whether positive or negative, is good as it can be used to determine what needs to remain status quo, what needs to be changed, and how changes can be made.

Jean Piaget Essay Example for Free

Jean Piaget Essay This case study is on a young girl named Debby. She was observed in a at her parent’s home over the last weekend. She is 3 years of age. She is the only child, and lives with both parents. She has her own bedroom. She loves anything Disney princesses, she also does not like dark colors, bright colors are her favorite and she likes the color pink. She like playing with dolls, playing kitchen, and she told me that her favorite thing was to ride in mummy’s car. Debby dislikes playing trucks and boy’s game, she did not have any problem playing with boys or girls  but while observed at a birthday party, she rather plays with girls, than to play with boys. She also does not like dark colors, bright colors are her favorite. She does go to speech therapy to work on her words as both parents are actively working professionals. Debby is a very fascinating young girl, and it was exciting to do a case study over her. For a child of age four, Debby is very active. Debby is average for her physical development. Debby is physically fit, and enjoys playing with others when. Because she was observed at their at home, some questions were directed to her mother. According to a growth  and weight chart, the average height for a 3 year old girl is 37 inches. Debby is 38 inches in height, and she weighs 36 pounds (CDC growth chart. ) Debby is a very active child. She enjoys running around every chance that she gets. When playing outside Debby can kick, throw, bounce, and catch a ball adequately. She is developing her eye-hand coordination. When asking her to do these tasks, Debby is able to run, she can hop on both feet, and she can jump up and down. She needs more time to get skipping down, but she tries her best. Debby is able to dress and undress herself without assistance. Debby likes the  independence of being able to pick out her clothes that she wants to wear. She is very comfortable using iPad and some other operating electronics in the house. One of her favorite activities to do is to paint and draw. While painting, she likes to make a mess, because she thinks that it is fun to paint with her hands. Debby is in the Pre- operational stage cognitively. Pre-operational stage is from ages 2 to 7, and Debby fits in this category, because she is 3 years old. Cognitively, Debby is in the normal category, because according to develop mentalists she is developing normal for her age. Examples are that Debby knows how to write letters in the alphabet. She knows how to write her name, she just does not know the correct order the letters go in. She is able to count, she is a good listener, and she is becoming interested in how to sound out certain words. These are just a few cognitive abilities, which are normal for 3 year olds. As each year passes, and as Debby continues to get older, cognitively she will continue to progress. Debby’s Language Development is improving. Debby does attend speech therapy. When she talks sometimes you really have to listen hard to what she is saying. When she gets excited  about something, she will start talking really fast, and we have to remind her to slow down. When she gets upset, she will normally start crying, so she is encouraged to use her words to explain what is wrong. Though sometimes, she say something which she means the opposite. Her basic speech problems are annunciation, and getting some sounds confused with one another. For example b’s and d’s. Speech has really helped her, she has only been going for a little over two months, and we can already see a drastic change in her words. On occasions, you will find Debby talking or discussing with herself. According to her  mother, she usually does this when she is trying to figure something out. I enjoyed watching this taking place. I also tried to test her about her memory and recollection. I asked her about what she does on her birthday because her birthday was the previous Sunday. She was able to tell me how mummy took her to the park. Her thinking ability is very superb Cognitively, Debby is s in the normal category for a 3 year old. In the Jean Piaget theory, she is in the pre-operational stage. She loves going to school and also like to try new thing. She is well behaved and according to mum, she always goes around to greet both the teachers and  students alike whenever she is entering or leaving the school. Debby is rapidly developing many social and emotional abilities and skills. Her growth and behavior reflects the abilities that are expected of her age. Debby is developing rapidly and cognitively, she is developing normally. On the issue of Moral development, there are some cases that she knows what is right. She has begun to know right from wrong. She has started to find others opinions of self to be important. Like on Sunday in church after service, their pastor came around to say hello and he greeted he by saying â€Å"what’s up men? † but she replied â€Å"I’m not a man, I’m a girl† everybody there just laugh at the way she responded. She possesses a lot self-controlling and is less aggressive but sometimes uses verbal threats like â€Å"you will be in trouble† or â€Å"I will slap you† but to my understanding, she did not even know the meaning of those words. I enjoyed my case study on Debby. Through it, I was able to learn many penetrating strategies to see and understand if children are progressing adequately, according to their age throughout the early stages of their life. It is crucial that children progress accordingly so they do  not fall behind in school and in life. After doing this case study I now know what tips and signs to look for when deciding if a child is progressing in all aspects of life. Debby compared to an average 3 year old is normal, her age and behavior are well correlated. I am amazed with her memory. I overheard her singing a Nigerian folklore and I asked he to sing it for us again and she did not miss too much from the lyrics. Debby is in Piaget Preoperational Stage as she was able to think about things symbolically and her language use becoming more mature but her still not completely logical. Also, Debby belongs to the Musculo-Anal in the Eriksons Stages of Development because she is self-sufficient in many activities, including toileting, she can feed herself, walking, and her talking is becoming clearer. I really enjoyed observing Debby, it was a great experience and I hope to put it into practice in my field of study.

The wife of martin guerre :: essays research papers

â€Å"†¦how can I deny the truth?† Although Bertrande is well-intentioned, her actions bring misery to everyone. Discuss. The notion of Bertrande de Rols in The Wife of Martin Guerre as having good intentions suggests not only that she was mindful of her own feelings in her pursuit of the truth, but also of the feelings of others. However, Bertrande’s intentions were to cleanse her soul and absolve herself from sin by indicting the impostor, Arnaud du Tilh. Yet, she undertakes this task considering the despair it would inflict upon the mesnie. These actions also are detrimental to Bertrande in causing her perhaps the most anguish and grief of all. Bertrande intends to uphold the status quo, yet she has due knowledge that pathway to the greater good will be harmful to her and the Mesnie. Bertrande’s intentions are to free her soul from the binds of the sin she committed by being the wife of Arnaud du Tilh. Bertrande’s loyalty to Martin shapes her response to being ‘imposed upon, deceived, betrayed into adultery’ and as she came to the inescapable conclusion that Arnaud was indeed an impostor, her first thoughts were to ‘rid herself of him’ and dissolve her guilt. As the epiphany occurs, the ‘spindle’ drops to the floor, unravelling the truth ‘finally, coldly, inescapably.’ This is immediately followed by the repetition of ‘I’ in Bertrande’s inner thoughts, Lewis using this pronoun to suggest the action Bertrande would take part in to condemn Arnaud du Tilh would be primarily based on her own personal escape from his treachery. Bertrande’s intentions are fundamentally to promote self preservation and to put her mind at ease. Nevertheless, Bertrande knows these self-centred intentions, when put into action, will ultimately be reflected by the displeasure and distress of her children and the Mesnie. ‘I am destroying the happiness of my family. And why? †¦ to free myself from the deceit which was consuming and killing me.’ Bertrande’s strong desire to free herself from the cunning of Arnaud du Tilh inevitably brought considerations of the Mesnie and her children to mind. ‘Her affection for her kindred rose about her in a wall implacable as stone’ as she was ‘condemned to solitude’ knowing the hurt her accusations against Arnaud inflicted upon the mesnie. Furthermore, the drawn out process of the trial brought ‘heart-breaking uncertainty,’ with Lewis clearly indicating through this use of language Bertrande’s awareness of the affect of her actions upon others.

Life Cycle Analysis for Brick

Life Cycle Analysis For Brick 1Materials are very important in construction industry because with the combination of different material, we can create a very strong and unique building form. There are many type of material that commonly used in the construction industry, for example the glass, woods, bricks, stones, marble, concretes and etc. Brick is one of the most commonly used materials in Malaysia, because almost every house in housing area was built by bricks. From this essay I want to give analysis about the brick life cycle included its origin and how the brick being used after the end of its life cycle. 2Brick was appeared since the beginning of the civilization, which is the ancient Mesopotamia around 8000 BC. (Think Brick Australia 2007) The thick clay and mud leave by the Tigris and Euphrates Rivers was reinforced with straw and shaped into brick and then dried in the sun. Bricks were glazed in a variety of colours as the time progressed and used to decorate the facades of the ziggurat, or temple towers, built as stairways to and for the Gods. In the end, people started to realize that when the wooden houses burned and the brick on the remaining chimneys had been strengthened, so fire-hardened bricks began to replace adobe ones in India and the Middle East. And the Romans used kiln-burned brick in conjunction with an efficient mortar of lime and volcanic ash to construct buildings that were both beautiful and last longer. Think Brick Australia 2007) 3Brick is a masonry unit of clay, formed into a rectangular prism while plastic and hardened by firing in a kiln. The manufacture of bricks is used easily workable and clayey materials and the materials are avoided to contain any large hard components or lumps of lime, this is to avoid crack and split of the brick. We can obtain clay on the surface of the ground. There are three principal form of clay used to manufactured clay brick which are surface clay, shales, and fire clays. The surface clays is sedimentary clays which found near the surface of the earth, shales is clay that have been subjected to high pressures until they have hardened almost to the form of slate, and the fire clays is clays which have found deeper in the ground than other types and to have refractory qualities. These three principal forms of clays have similar chemical compositions but appear in different physical. The clays can easily be found and to extract because usually we can find it in the ground surface. After the clay has been extract from the ground, it covered with water, usually used to be work by hand with special hoe. There are several processes to form a brick which are soft mud process, stiff mud process and dry-press process. (Ching and Adams 2001, 12. 06) The soft mud process refers to forming brick by molding relatively wet clay having a moisture content of 20 percent to 30 percent. (Ching and Adams 2001, 12. 06) The Stiff mud process refers to forming brick and structural tile by extruding stiff but plastic clay having moisture content of 12 percent to 15 percent and then the de-airing machine will removes air and eliminating holes and bubbles in the clay. Ching and Adams 2001, 12. 06) After that the clay is force through die and cutting the extrusion to length with wires before to heat the finish in the kiln. The dry-press process refers to forming brick by molding relatively dry or low plasticity clay which having moisture content of 5 percent to 7 percent under high pressure, the resulting of this process is sharp-edged, smooth-surfaced bricks. (Ching and Adams 2001, 12. 06) 4The most imp ortant step to form a stronger brick is through the drying and firing process. There are three different kinds generally used the humidity system of drying can be applied to any type of dryer, as the term humidity drying represents a process rather than a form of structural design. Humidity drying may be divided into three stages: first is the heating stage, during which the clay is gradually heated up in an atmosphere of relatively high humidity, this prevents excessive cracking or distorting on the face of the brick. After that is the drying period, in which the air is heated to a maximum temperature for the clay being dried, the humidity is gradually decreased to allow the clay to dry uniformly all the way through. And the third which is the cooling stage, in which the temperature is gradually decreased to uniformity. The clay is not fully dried when placed in the kiln. Hygroscopic water is not driven off at ordinary temperatures or even at the boiling point of water. In fact, the temperature often rises quite a bit above the boiling point before the water is completely evolved. The watersmoking is accomplished by fire in the kiln furnaces. Wood is frequently used for this purpose, to avoid sooting. In the watersmoking eriod it is desired to heat up the brick, evaporate and remove the moisture, and to accomplish this successfully, it is very necessary that draft be strong. The watersmoking is the most critical point in the life of the brick. The process must be carried very slowly the water in coming out of the clay may crack the surface. After the watersmoking is completed, the temperature is increase to that required in oxidation. Oxidation begins in the later stages of vitrification, but the greater part occurs between the temperatures of 800oF and 1300oF. At this stage most of the impurities are given off and the metals constituting the clay are changed to their respective oxides. The highest temperature reached at this point is usually near 2000oF. 5Brick grade designates the durability of a brick unit when exposed to weathering. The United States is divided into three weathering regions, severe, moderate, and negligible, according to annual winter rainfall and the annual number of freezing-cycle days. (Ching and Adams 2001, 12. 6) Brick is graded for use in each region according to compressive strength, maximum water absorption, and maximum saturation coefficient. The three grades are SW is brick suitable for exposure to severe weathering, as when in contact with the ground or used on surfaces likely to be permeated with water in subfreezing temperatures; minimum compressive strength of 17238 kPa. (Ching and Adams 2001, 12. 06) MW is brick suitable for exposure to moderate weathering, as when used above grade on surfaces unlikely to be permeated with water in subfreezing temperatures; minimum compressive strength of 15169 kPa. Ching and Adams 2001, 12. 06) NW is brick suitable for exposure to negligible weathering, as when used as a backup or interior masonry; minimum compressive strength of 18243 kPa. (Ching and Adams 2001, 12. 06) 6The manual production of the bricks involves mainly four operations namely, soil preparation, moulding, drying and firing. The main process in which energy is consumed is firing of bricks. The amount of total coal required is about 18 tonnes to 22 tonnes depending upon the weather condition, quality of coal, etc. A tonne of coal gives about 12. 3MJ to 13. 3MJ depending upon the quality of the coal generally transported from far off distances. (Gumaste n. d. ) The energy required to produce each brick inclusive of transportation comes to about 5 MJ per brick. (Gumaste n. d. ) Advantage of using bricks One of the advantages of using brick to build building is because brick is a high thermal mass material, it absorb heat throughout the day and release it slowly at night, this is ensuring internal temperatures are consistent throughout the day and night. The result is we’re able to have comfortable and healthy living and working environment in which to enjoy stable temperatures throughout the year. Brick building also very sustainable because they highly durable, offer long term life performance, low maintenance, and energy efficient and recyclable. But bricks have been labeled as having high embodied energy due to their process of manufacture. However, in measuring sustainability it is necessary to take into account a material’s life cycle performance, s well as the amount of energy consumed in the manufacturing process. And a recent research by think brick demonstrates that the proportion of embodied energy of clay bricks for the modern semi-detached home is equal to just 1. 87 percent of the over all heating requirement for the home over its 150 year life. Moreover during the manufacture of brick, very little clay is wasted, and those unfired waste clay is reused in the manufacturing process and less than perfect fired bricks are crushed and used as a aggregates in other parts of the building industry. In conclusion, brick has a very high embodied energy during manufacture, especially in the firing system which required many of the energy to burn the brick, but it is highly durable, offer long term life performance and low maintenance so it is very suitable as a material to built the long stay building.

The Need And Importance Of Learner Management Systems Education Essay

IntroductionI have worked in the Work based Learning proviso and hence understands the demand and importance of learner direction systems†¦ without which the whole system will be in muss. There is a batch of conformity demand as the programmes we provide are chiefly funded through the SFA ( Skills Funding Agency ) or ESF ( European Social support ) and inspected by the Ofsted. It is non possible for a individual individual to retrieve or organize all these things hence there is a demand for a LMS which will remind you to make the assorted things, generate appropriate studies, co-ordinate between the scholar, employer, coach, presenting organic structure and the support organic structure. Work Based Learning has been defined nationally as ‘Learning for, at or through work ‘ Learning for work loosely encompasses ‘anything which can be labeled ‘vocational ‘ as delivered in school, college, sandwich classs, in BTEC Nationals in hairdressing/beauty and manner, mechanical technology, humanistic disciplines and ocular, or even wellness, kid and societal attention. Learning at work every bit related to developing and development delivered in-company such as Business direction accomplishments, client service, wellness and safety ; and Learning through work that includes the application of job-related acquisition ( perchance acquired elsewhere ) and the accomplishments and cognition acquired in the procedure of making the occupation such as athleticss manager, attention work, mechanics. Work Based Learning is one of the most popular flagship of the current and old authoritiess. The degrees of hapless attainment of accomplishments in the instruction sector had become a serious affair of grave concern. More and more kids were go forthing school without any accomplishments, needed cognition or direct vocational experience. They were mostly unemployable due to hapless literacy, numeracy, scientific and ICT accomplishments and represent a immense societal liability, which was manifested by their engagement in anti societal offenses, or hapless negative behavior forms, taking to detonations of their admittances into unafraid disciplinary penal establishments. The deficiency of accomplishments of the Youth in United Kingdom is besides a major concern to industry and employers. Rather than prosecute in ne'er stoping blasted addition, the new Government has launched enterprises that appear to go on with known policies of promoting work based larning chiefly Apprenticeship schemes to be equipped with the critical accomplishments needed to be gainfully employed. This survey relates merely to the funded work based learning proviso, all of which are in range for review by Ofsted ( Office for Standards in Education ) and audit by the support organic structures like SFA ( Skills Funding Agency ) , ESF ( European Social Funding ) etc. The procedures involved in the Work based proviso are much complex than the normal preparation colleges, besides as they are funded proviso they need to keep grounds that the money given by the support organic structures have been spent right as by the eligibility counsel and the undertaking counsel. Work Based Learning proviso involves three chief participants – the supplier, the employer and the scholar. As the complexnesss kept increasing the suppliers felt it really hard to pull off efficaciously the whole procedure this gave rise to the demand of a scholar direction system ( besides known as direction information system ) to administrate and pull off the whole procedure efficaciously and besides to cut down staffing cost and mistakes. Today there are tonss of package which are used by the WBL suppliers in UK, the chief being PICS by pellcomp package and Maytas by Tribal. Learner direction system does the occupation of the director†¦ it is non merely for pull offing the scholars but besides for helping the supplier for record maintaining, coverage and for communicating between the employer, supplier and the scholar. Learner Management system has ever been confused with the e-learning but really LMS is a portion of E-learning. By ‘e-learning ‘ we mean: ‘The bringing and disposal of larning chances and support via computing machine, networked and web-based engineering to assist single public presentation and development ‘ ( Pollard and Hillage, 2001 ) . There are assorted engineerings which contribute to e-learning for WBL suppliers viz. : Learner Management System – for pull offing scholar, employers, learning staff and for assorted conformity demands Learning Content direction system – It involves development, direction and publication of the content that will typically be delivered via a Learning Environment Learning Environment – Learning Environment is a environment where scholars and learning staff can interacts. VLE is a type of web-based acquisition environment which brings together in an incorporate environment, a scope of resources that enable scholars and staff to interact online, and includes content bringing and trailing. Learner Assessment System or E-portfolios – for on-line testing or measuring scholars A batch of research has been done on E-learning and VLE and besides Becta has been making research on the e-maturity of WBL suppliers, Becta research has greatly influenced this research and besides relevant information has been used from the Becta research as a secondary information which has formed the portion of determination of this research.RESEARCH AIMThe purpose of the proposed research is to look into the user satisfaction of the Learner Management System used by the funded Work Based Learning Suppliers in Greater London.Research OBJECTIVESIts specific aims are to: Identify tendencies for WBL suppliers in their use of Learning Management systems look into the impact of Learning Management systems on the overall quality of proviso place for what different intent is the LMS being used by the suppliers look into the degree of staff accomplishments in the usage of LMS place whether clip spend by the user utilizing LMS has impact on the user satisfaction place how cost effectual the LMS system is and what impact it has on user satisfactionRESEARCH HYPOTHESISThe user satisfaction of the Learning Management systems amongst funded Work Based Learning suppliers depends on the undermentioned variables – Users skill Cost effectivity Functions the LMS supports User Skill will include how competent the users are in utilizing the Learning Management system which in bend will depend upon their general IT or package accomplishments and besides for how long they have been utilizing the system and how frequently they use the system. Cost Effectiveness will include the existent cost of the LMS, clip saved by the users utilizing the LMS, the decrease in the labor cost and the mistake decrease Functions the LMS support will include how helpful the LMS is in back uping through the assorted procedures of WBL, how good incorporate it is with other sytems A user will be more satisfied with the LMS if he/she is more skilled A user will be more satisfied with the LMS if it is cost-efficient A user will be more satisfied with the LMS if it support more maps Research Background: A turning tendency of instruction and preparation in UK is Work based Learning where employees, particularly immature 1s, are provided assorted signifiers of chances to develop and better their numeracy, literacy, ICT, client service and other related proficient and vocational accomplishments, cognition and practical industrial cognize how. It is widely acknowledged that to assist concerns to win in this clip of economic challenge, it is critical that employers invest in accomplishments. Training additions productiveness in the short termA – and employers who do n't develop are two times more likely to neglect than those who do. Research shows that three in four concern people ( 76 % ) believe that their organisation would non win without investing in preparation, hence Work Based Learning is a really of import signifier of acquisition. Apprenticeships and Train to Derive are two most of import funded work based larning programmes.. Apprenticeship is a system of developing a new coevals of practicians of a accomplishment. Apprentices ( or in early modern use â€Å" learners † ) or proteges construct their callings from apprenticeships. Most of their preparation is done while working for an employer who helps the learners learn their trade, in exchange for their go oning labor for an in agreement period after they become skilled. Theoretical instruction may besides be involved, informally via the workplace and/or by go toing vocational schools while still being paid by the employer Apprenticeships have a long tradition in the United Kingdom, dating back to around the twelfth century and flourishing by the fourteenth century. The parents or defenders of a child would hold with a Guild ‘s Master craftsman the conditions for an apprenticeship which would adhere the child for 5-9 old ages ( e.g. from age 14 to 21 ) . They would pay a premium to the craftsman and the contract would be recorded in an indentation. In 1563, the Statute of Artificers and Apprentices was passed to modulate and protect the apprenticeship system, prohibiting anyone from practising a trade or trade without first functioning a 7-year period as an learner to a maestro. From 1601, ‘parish ‘ apprenticeships under the Elizabethan Poor Law came to be used as a manner of supplying for hapless, illicit and orphaned kids of both sexes alongside the regular system of skilled apprenticeships, which tended to supply for male childs from somewhat more flush backgrounds. These parish apprenticeships, which could be created with the acquiescence of two Justices of the Peace, supplied learners for businesss of lower position such as farm labouring, brick devising and humble family service. In the early old ages of the Industrial Revolution entrepreneurs began to defy the limitations of the apprenticeship system, and a legal opinion established that the Statute of Apprentices did non use to trades that were non in being when it was passed in 1563, therefore excepting many new eighteenth century industries. In 1814 compulsory apprenticeship by indentation was abolished. The consequence of this was the low end product of skilled forces in technological industries, which in bend relegated UK into the lower ranks of advanced societies. Since so Apprenticeship has ever been really popular and besides has been the most favoured by the assorted authoritiess. As employees, learners earn a pay and work aboard experient staff to derive job-specific accomplishments. Off the occupation, normally on a day-release footing, learners receive preparation to work towards nationally recognised makings. Anyone life in England, over 16 and non in full-time instruction can use. Apprenticeships can take between one and four old ages to finish depending on the degree of Apprenticeship, the learners ‘ ability and the industry sector. Train to Gain is the authorities ‘s flagship supplying accomplishments based developing to employees. Train to Gain is portion of the Governments Solutions for Business, a broad portfolio of extremely targeted, publically funded concern support merchandises and services, designed to helpA eligible English concerns grow and win. As the national accomplishments service Train to Derive: purposes to run into the demands of employers of all sizes and from all sectors to better the accomplishments of their employees as a path to bettering their concern public presentation purposes to promote all concerns and persons to value and gain the benefits that larning and accomplishments can convey is a valuable resource for employers, unlocking employees ‘ possible and increasing company productiveness A wide scope of preparation is covered – from basic degree accomplishments to Level 2, Level 3 and other higher-level accomplishments such as Leadership and Management. As of today Train to Derive is to stop by July 2011 and new support programme will replace it but it will merely fund degree 2 makings and most suppliers are expected to exchange to apprenticeships programmes. Coalition Government Policy: In acknowledgment of the turning importance of work based acquisition, the new Coalition Government in United Kingdom has lent its support to this industrial tendency: The Secretary of State for Education, Michael Gove, commissioned Professor Alison Wolf of King ‘s College London to transport out an independent reappraisal of vocational instruction. She was asked to see how vocational instruction for 14- to 19-year-olds can be improvedA in order toA promote successful patterned advance into the labour market and into higher degree instruction and preparation paths. She was besides asked to supply practical recommendations to assist inform future policy way, taking into history current fiscal restraints. The reappraisal has been informed by over 400 pieces of grounds from the populace, a figure of visits to colleges, academies and developing suppliers, and interviews and treatment Sessionss with cardinal spouses in the sector, and cardinal recommendations in the reportA include the followers: incentivising immature people to take the most valuable vocational makings pre-16, whileA taking inducements to take big Numberss of vocational makings to the hurt of nucleus faculty member survey presenting rules to steer survey programmes for immature people on vocational paths post-16 to guarantee they are deriving accomplishments which will take to progression into a assortment of occupations or further acquisition, in peculiar, to guarantee that those who have non secured a good base on balls in English and mathematics in GCSE continue to analyze those topics measuring the bringing construction and content of apprenticeships to guarantee they present the right accomplishments for the workplace doing certain the regulative frameworkA moves quicklyA off from recognizing single makings to modulating presenting administrations taking the demand that all makings offered to 14- to 19-year-olds tantrum within the Qualifications and Credit Framework, which has had a damaging consequence on their rightness and has left spreads in the market enabling FE lectors and professionals to learn in schools, guaranting immature people are being taught by those best suitable Before the Learner Management Systems or package the coverage and tracking all of scholars, classs and coachs was done through the usage of a individual maestro spreadsheet. To enable studies to be compiled, transcripts of this maestro spreadsheet would be taken and edited, which proved to be cumbersome, non really effectual and really clip consuming. Besides these chief spreadsheets were merely available at the chief office which meant that any coach or scholars who would necessitate some information needs to come to the office or when transcripts of this spreadsheet were taken off site, which on occasion happened, nevertheless this so lead to issues with versions of the maestro as updates may hold been done to this dispersed sheet off site whist other members of staff may hold made alterations to the on site transcript. Leading to issues with truth of the overall maestro spreadsheet, this was one of the trouble faced by most suppliers before the Learner Management Systems like PICS and Maytas came in the image. PICS is the most popular Learner Management system used by the Work Based Learning Suppliers in England. The chief characteristics of PICS are – Research Methodology: The system of roll uping informations for research undertakings is known as research methodological analysis The research will be undertaken in two phases: a literature reappraisal on the usage of e-learning in work-based learning proviso, covering authorities strategic and research publications, research by the LSC, Becta, JSIC and other bureaus, academic diaries, industry-related web sites and publications, specific undertaking studies and ratings. desk research including interviews and questionnaires with directors and practicians – which involves admin staff, coachs, assessors and Internal Verifier. Exploratory surveies will be conducted to derive acquaintance with the topical countries and generate thoughts through the reappraisal of available literature from beginnings such as Becta research, LSC ( now Skill Funding Agency ) , JISC and others. Pilot interview – restructure the inquiries as necessary Pilot usage of questionnaire – restructure the inquiries as necessary Contact inside informations of assorted s Letters/Emails bespeaking purpose, purposes and aims of the survey would be sent out to different administrations presenting Work Based Learning proviso in Greater London. Online questionnaire or paper based questionnaires will be sent out to the directors of these administrations. Online Questionnaires or paper based questionnaires will be sent out to the bringing staff of the administrations presenting Train to Derive proviso. Interviews will be conducted with cardinal staff of the administrations bringing work based learning proviso Analysis of secondary informations such as becta research and published one-year studies and academic diaries. Consideration of the informations and forms found in all of the administrations will be used in concurrence with academic theory to seek to explicate the findings and reply the research aims posed in subdivision Mistake: Reference beginning non found.Validity and ReliabilityIn the design of the research attack I have considered the followers: Internal cogency – Increased through usage of multiple beginnings of grounds, structured interviews and questionnaires ( both closed and unfastened inquiries ) . The design of inquiries and study will be based on apprehension of the theory from the literature and pilot testing of the interview and questionnaire will be used to do certain inquiries are understood as intended. External cogency – Multiple instances considered to analyze whether findings can be generalised over a figure of administrations. There is no demand to do a statistical analysis of the consequences for generalization here as the attack chosen examines patterns and their effectivity. The purpose is to explicate the findings and explore generalisability through a comparing of findings with theory. Reliability – Structured interviews with inquiries derived from literature in order to analyze instances in same manner. Surveies to endorse up the interviews and obtain positions from a wider group. Questionnaires all administered at the same clip and in controlled mode, account to guarantee participants all understand research in same manner.Research Ethical motivesPlease see Appendix A to this proposal, the Business School Ethics Review Form. This covers the chief points to be addressed here, but in drumhead: The interviewees and study participants will be given a clear written description of the intent, range and intended results of the research. The type of information required for the research will be clearly stated as will the policy for namelessness and confidentiality. The research will be carried out in a manner that will guarantee confidentiality of the participant administrations and the single participants in the studies. The administrations which participate in the research will non be named in the thesis, nor will the interviewees and the questionnaires will be anon. . The interview inquiries and questionnaire will be designed to analyze merely the patterns of KM, no confidential merchandise or client information will be required. Even so, I have highlighted this country for possible ethical struggle in subdivision 5 of the Ethics Review Form. This is because confidential information may be discussed in the interviews and besides commented upon in the questionnaires, this information will non be included in a manner which will transgress confidentiality in the thesis. The semi-structured interviews will get down with an organizational questionnaire to derive company information such as figure of employees, figure of research staff, one-year turnover, market sector, merchandises ( type, figure of different merchandises, merchandise volume and value ) . The balance will cover a series of unfastened ended inquiries to discourse the KM patterns in order to derive an apprehension of the attack taken, the construction and effectivity, how and why certain schemes work whilst others are less effectual. Each participant will be asked to reply indistinguishable inquiries, but the order of the inquiries will non needfully be fixed as this may take away from the flow of the interview. The study is intended to supplement informations from interviews and sample more widely the patterns and single perceptual experiences in the administration. The purpose is to derive an apprehension of how the cognition schemes work and besides the sentiments and apprehension of the employees. The questionnaire will hold structured inquiries with fit responses in order to map the KM features of the administration[ 1 ]. There will besides be unfastened inquiries for participants to do remarks on the assorted facets of KM in their administration My attack to the design of the interview and study is as follows: Preliminary model built on the reappraisal of theory from academic literature prior to design of questionnaires and structured interviews Pilot interview – restructure the inquiries as necessary Pilot usage of questionnaire – restructure the inquiries as necessary Interviews – notes taken during entering cardinal words and phrases and making full record instantly after interview Survey – questionnaires explained and handed out/ collected during sessionChapter 4: FindingsIn this subdivision the responses obtained from the questionnaire administered to the users are summarized and are presented to help treatment in subdivision 5. 4.1 Management Staff Survey A sum of 21 questionnaires were obtained for the direction staff study but out of which 3 of them were non wholly filled and had batch of compulsory inquiries unfilled hence they were non included in the analysis.

John Locke Philosophy Essay

John Locke Philosophy Essay Free Online Research Papers From the philosophy of substance and cognition arrives John Lockes philosphy of language. Locke argues humans have an intellect that evolves heavly upon communication and use of language to advance our species. Ideas are the basis of all knowledge, words appropriately fit into this category, subdivisions of ideas. However a large issue rest on the misreprestation of words therefore the misreprestation of ideas from individual to individual. Locke advises us to take percautions while using words, for misuse can retard science, communitaction and the entire human race. Humans unlike any other species on Earth have a superior intilect allowing for supremacy above others animals. We understand immense vocabulary, technology and personal advancments. In order for such progression communication is a requirement. Ideas are passed in forms of words from one person to another person in hopes of relating ones concepts. It is to be noted, Locke states that words do not represent the physical object being spoken of, but the personal idea one gets from such a word. Communication then for Locke is being hindered. To think that a persons exact thought is being reconstituted in its exact form within another cannot occur. This is where Lockes argument lies, misreprestation and abuse of our words and therefore our every idea. Locke remarks again, that words do not represent an exact physical object in your brain, it is rather reflection and relation to such a word or statement. Since every persons experience is not the same, our knowledge is not reflective of that, experienced by the communicator. Rather Locke argues â€Å"The use then of words, is to be sensible marks of ideas; and the ideas they stand for, are their proper and immediate signification.† . This statement of course is an objective for Locke and the world to use as the basis of communication. The word should be an immidiate and universally agreed upon idea for all. Again Locke agrues, â€Å"[I]n all that great extent wherein the mind wanders, in those remote speculations, it may seem to be elevated with, it stirs not one jot beyond those ideas, which sense or reflection, have offered for its contemplation.† Ones Ideas must not run one fragment over which it is intended. This quote can correlate to Lockes thoughts on Nominal essences, we think of words more in abstract terms, colour, shape, texture. Using Nominal ideas attached to words is seen as harmful. Locke would rather us acknowledge words for a more persise universally understanding. Philosopher Merleau-Ponty, Maurice writes â€Å"There is a general function of substitution and replacement which enables us to gain access to the abstract significance of experiences which we have not actually had, for example, to speak of what we have not seen.† For expample the term God, is a generally agreed upon idea, however the context of the idea will change from person to person. Locke uses this word â€Å"God† throughout his text, though every reader may intrept differently. Locke again wrote â€Å"We are farther to consider concerning perception, that the ideas we receive by sensation, are often in grown people altered by the judgment, without our taking notice of it.† Although judgement, culture and previous knowledge will all effect how we preseve ideas. Locke suggests some solutions, a subject should never use a word without a lucid idea of its content, use words that correlate with your correspondents, define innuendos or ambiguous words, and the use of consistancy. Locke acknowldges that humans and language have inherent flaws. His suggestions concerning language could lead to advancing knowledge and greatly better enhance our communication skill amoung human.

How to Extract Caffeine From Tea

How to Extract Caffeine From Tea Plants and other natural materials are sources of many chemicals. Sometimes you want to isolate a single compound from the thousands that may be present. Here is an example of how to use solvent extraction to isolate and purify caffeine from tea. The same principle may be used to extract other chemicals from natural sources. Caffeine From Tea: Materials List 2 tea bagsDichloromethane0.2 M NaOH (sodium hydroxide)Celite (diatomaceous earth - silicon dioxide)HexaneDiethyl ether2-propanol (isopropyl alcohol) Procedure Extraction of Caffeine: Open the tea bags and weigh the contents. This will help you determine how well your procedure worked.Place the tea leaves in a 125-ml Erlenmeyer flask.Add 20 ml dichloromethane and 10 ml 0.2 M NaOH.Extraction: Seal the flask and gently swirl it for 5-10 minutes to allow the solvent mixture to penetrate the leaves. Caffeine dissolves in the solvent, while most of the other compounds in the leaves do not. Also, caffeine is more soluble in dichloromethane than it is in water.Filtration: Use a Buchner funnel, filter paper, and Celite to use vacuum filtration to separate the tea leaves from the solution. To do this, dampen the filter paper with dichloromethane, add a Celite pad (about 3 grams Celite). Turn on the vacuum and slowly pour the solution over the Celite. Rinse the Celite with 15 ml dichloromethane. At this point, you may discard the tea leaves. Retain the liquid you have collected it contains the caffeine.In a fume hood, gently heat a 100-ml beaker containing the washings to evaporate the solvent. Purification of Caffeine: The solid that remains after the solvent has evaporated contains caffeine and several other compounds. You need to separate the caffeine from these compounds. One method is to use the different solubility of caffeine versus other compounds to purify it. Allow the beaker to cool. Wash the crude caffeine with 1 ml portions of a 1:1 mixture of hexane and diethyl ether.Carefully use a pipette to remove the liquid. Retain the solid caffeine.Dissolve the impure caffeine in 2 ml dichloromethane. Filter the liquid through a thin layer of cotton into a small test tube. Rinse the beaker twice with 0.5 ml portions of dichloromethane and filter the liquid through the cotton to minimize the loss of caffeine.in a fume hood, heat the test tube in a warm water bath (50-60 Â °C) to evaporate the solvent.Leave the test tube in the warm water bath. Add 2-propanol a drop at a time until the solid dissolves. Use the minimum amount required. This should be no more than 2 milliliters.Now you can remove the test tube from the water bath and allow it to cool to room temperature.Add 1 ml of hexane to the test tube. This will cause the caffeine to crystallize out of solution.Carefully remove the liquid using a pipette, leaving the purified caffeine.Wash the caffeine with 1 ml of a 1:1 mix of hexane and diethyl ether. Use a pipette to remove the liquid. Allow the solid to dry before weighing it to determine your yield. With any purification, its a good idea to check the melting point of the sample. This will give you an idea of how pure it is. The melting point of caffeine is 234 Â °C. Additional Methods Another way to extract caffeine from tea is to brew tea in hot water, allow it to cool to room temperature or below, and add dichloromethane to the tea. The caffeine preferentially dissolves in dichloromethane, so if you swirl the solution and allow the solvent layers to separate. you will get caffeine in the heavier dichloromethane layer. The top layer is decaffeinated tea. If you remove the dichloromethane layer and evaporate the solvent, you will get slightly impure greenish-yellow crystalline caffeine. Safety Information There are hazards associated with these and any chemicals used in a lab procedure. Be sure to read the MSDS for each chemical and wear safety goggles, a lab coat, gloves, and other appropriate lab attire. In general, be aware the solvents are flammable and should be kept away from open flames. A fume hood is used because the chemicals may be irritating or toxic. Avoid contact with sodium hydroxide solution, as it is caustic and can cause a chemical burn on contact. Although you encounter caffeine in coffee, tea, and other foods, it is toxic in relatively low doses. Dont taste your product!
