Arrhenius Acid Definition and Examples

Arrhenius Acid Definition and Examples An Arrhenius acid is a substance that dissociates in  water to form hydrogen ions or protons. In other words, it increases the number of H ions in the water. In contrast, an Arrhenius base dissociates in water to form hydroxide ions, OH-. The H ion is also associated with the water molecule in the form of a hydronium ion, H3O and follows the reaction: acid H2O → H3O conjugate base What this means is that, in practice, there arent free hydrogen cations floating around in aqueous solution. Rather, the extra hydrogen forms hydronium ions. In more discussions, the concentration of hydrogen ions and hydronium ions are considered interchangeable, but its more accurate to describe hydronium ion formation. According to the Arrhenius description of acids and bases, the water molecule consists of a proton and a hydroxide ion. The acid-base reaction is considered a type of neutralization reaction where the acid and base react to yield water and a salt. Acidity and alkalinity describe the concentration of hydrogen ions (acidity) and hydroxide ions (alkalinity). Examples of Arrhenius Acids A good example of an Arrhenius acid is hydrochloric acid, HCl. It dissolves in water to form the hydrogen ion and chlorine ion: HCl → H (aq) Cl- (aq) Its considered an Arrhenius acid because the dissociation increases the number of hydrogen ions in the aqueous solution. Other examples of Arrhenius acids include sulfuric acid (H2SO4), hydrobromic acid (HBr),  and nitric acid (HNO3). Examples of Arrhenius bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).

Monster A critical analysis Essays

Monster A critical analysis Essays Monster A critical analysis Essay Monster A critical analysis Essay Essay Topic: Film Monster is possibly the most powerful film anyone could ever wish to see. In terms of using a punch to deliver its message this film is the Tyson of this cinematic generation of films. This movie pushes the boundaries of thematic content and attempts to do what few films are brave enough to do, i. e. humanise a serial killer. It is the performance, if calling it that does it enough justice, of Charlise Theron, which makes this boundary pushing not only possible, but also successful. This essay will take a look at this complex story and attempt to examine its relationship with the plot, specifically how the plot is constructed and how it distinctly tells this story. In attempting to create a film like monster, the filmmakers are faced with very real challenges. Now every film it can be said, is challenging to make, but a film this complex, this real, and this emotionally demanding is always going to be tricky. The filmmakers are trying to portray a specific message, that is to say monster is very thematic in its story content. It takes a look at the influences in a persons life, which might possibly lead up to that person going so far as to commit murder. The danger with this is that it could come across as though the film is justifying the murders. I feel that Patty Jenkins manages to strike a balance between overly sympathising with Aileen and making us judge her, rather giving some sense of understanding. She does this by showing Aileens human side and by telling her very complex story in a passionate, real, often hard-hitting way. The problem with telling a biographic story is that the real plot might not naturally fit a specific plot structure, but the filmmakers have managed (however accurately, Im not sure) to construct the plot of Monster in an incredibly detailed, thoughtful and emotionally engaging way. While the story itself spans perhaps twenty years, the plot highlights the most dramatic events and constructs them in such a way, in such an order so as to drive home the themes and messages of Monster in the most accessible and poignant way. The first act begins with the young Aileen. Aided by the voice over narration we learn some of the necessary background information, detailing Aileens tragic childhood. We are given clues as to how and why she started prostituting herself as well as her social/economic background. These all lay a strong foundation from which the story and our understanding can be built on. The first few scenes of the young Aileen hook us into the story. We hear about how Aileen dreamed of becoming famous, of rising out of her situation. They also hint toward the tone and mood, i. e. the genre of the film. It is through this clever use of narration that we can closely identify with, i. e. become familiar with her attitude to life, her world and history of dilemmas. We hear how she always wanted to be taken to a new life, and would do anything (anyone) who she thought might help her get where she wanted to go. These words echo with us as we dissolve forward to the life of the adult Aileen, leaving us to fill in some of the gaps, guessing how messed up her life must have got. We enter Aileens adult life with a lonely shot of her sitting by the highway. This is very appropriate as the previous shot was of her as a teenage girl getting into the car of a strange man on the side of a main road. We can guess that this pattern has been ongoing and we pick up with the adult her having just finished with a client. Soon thereafter the plot takes us right into the inticing incident. In a lonely roadside bar we meet Salvie, a lesbian girl who herself has been searching for something, love and understanding. It is this confrontational meeting of Salvie and Aileen which propels the plot forward. It introduces a brand new element into Aileens life, which sets it off on a changed course we later learn that she was contemplating suicide. At first Aileen is unsure of her how she feels about Sylvie, but it is after Sylvie has invited her out that night, that she realises she has potentially found the friend she never had and always wanted. They go out to the ice rink and soon find themselves involved in a passionate love-making session outside. Suddenly Aileen has found direction. She wants nothing more than to be with Sylvie. This leads up to the first act climax and first major turning point. Aileen returns to the highways to ply her trade, in order to make much needed money. A dubious looking customer soon picks her up. Then in a very disturbing scene, he beats and sodomises her. She manages to free herself and using his gun, shoots him, and then drives off with his car and money. This plot point sets the scene for the rest of the movie. Aileen has committed murder. The atrocities committed to her fuel her hatred for men, which will motivate her to continue her murder spree. She also discovers a means to make lots of money. She also has a goal, for the major plot of the movie is surrounding her murders, indeed, the Sylivie/Aileen plot is also a major plot, but the two plots are so intermingled that it is hard to see them as mutually exclusive. Nonetheless, this climax takes us straight into act two, as Aileen Rushes to make her appointment with Sylvie. After some convincing Sylvie agrees to run away with her and spend at least one week with her. There is a lull in the pace as we see a montage of them renting a hotel, going out, living the dream life they had both always wanted. But soon there is a minor set back. Sylvie goes home to get some cloths and is confronted by her aunt who reprimands her. Sylvie manages to not be deterred and passes the test of her character growth (or de-growth) as she chooses to go her own way with Aileen. Then comes another plot point. In an emotional, reminiscing scene, Aileen tells Sylvie how she always wanted to be president and that she was once told that all you need in life is Love and to believe in yourself. This motivates Aileen to go out and look for a real job. She is extremely unsuccessful and the old Aileen resurfaces as she loses her cool with an obnoxious potential employer. Straight thereafter Aileen is picked up by a corrupt cop who forces her into a sexual favour. These two scenes refocus the plot. We can see that Aileen can do nothing but prostitute herself and they also re-affirm her hatred for men, which will drive her onto more murders. By about the half-way point of the movie, Aileen reaches a point of no return. In a previous confrontational scene in which Sylvie accuses her of not providing for them, Aileen had told Sylvie about the first murder, but she agrees to go out and whore for money. The point of no return comes when in a car with the guy; she hesitates, hesitates, then pulls out her gun and shoots him. She is now a murderer. She knows again what her goal is; survival by murder. She feels that she is doing it for Sylvie and indeed shows us that she loves her in her own way. In a powerfully passionate scene and no-return point in the Sylvie/Aileen plot, Aileen tells Sylvie that she loves her and the two make love. The rest of act two involves a few more murders and some set backs in their relationship. Sylvie goes out to the bar attempting to meet new people, and upsets Aileen. They go to funworld and things look on track once again, as they also make plans for their trip to the Florida Keys. All good times must come to an end, and this happens as, in what is in my opinion the act two climax, they have a car crash and end up on the run. Aileen tells her about the murders and they now have a new clearly defined goal, that is to avoid capture. Act three especially the last fifteen minutes are extremely intense and engaging. The story continues as previous but at a more intense and emotionally engaging level. Sylvie in a surprising and lady MacBeth look a like scene, tells Aileen that she just needs to carry on killing as they need to live. In the most extreme depiction of the murders, Aileen kills a John who was very benign and just wished to help her. Then she mistakenly kills a cop. They realise that things are getting out of hand and Aileen sends Sylvie on ahead or home (not sure) so that she can meet up with her later. She is ultimately however picked up by the cops. The film doesnt relent there as we are dragged ever closer by the power mostly of Charlises performance and specifically the parallel editing in the jail scene. Aileen and Sylvie have a phone conversation, and they both profess their undying love. Matching the very subtle, slow camera movement away from Sylvie, is her ever more dubious questioning. It is a very sudden, very tragic moment when the pennie drops and at various times the audience become aware of the betrayal, albeit understandable, taking place. It is even more tragic to see Aileens response as she admits solely to the murders, saving her only true love of any punishment, thus conveying beautifully the films major theme of the desperation love can drive you to. In the final shot of Aileen being led to the electric chair, her narration is heard. The last hard-hitting message comes as, commenting on something she had heard when she was young about reaching your dreams, she says cynically I guess they have to tell you something. Upon first watching it, I failed to realise how structured this movie actually was. But it is through movies like this that my faith in the Hollywood formula is being reborn. This movie is by no means boring, tiresome or old. It is just perfectly structured. From the first frame it grabs you by the collar and engages you in a two-hour ride of emotions. It is an incredibly difficult story to tell. It deals with issues that many feel are better left undelt with and thus does not appeal to everyone. We are not forced to like Aileen. There are constant emotional checks that cause us to examine our sentiments. Indeed we can pity her, but not necessarily forgive or excuse her behaviour. What this movie does do and I feel this was the filmmakers intention is get us to think a little harder about our own life, our treatment of others our place in society and those less fortunate than us. It also makes us think a bit more before judging someones actions, as we dont necessarily understand their background. It makes us question what a monster is, and if indeed a monster is ever a monster or just someone similar to us who has had a life to tough for them to handle. The judgements to these philosophies are left up to the audience to make, but the reason theses themes and questions are put across so powerfully in this story is definitely in large part as a result of the construction of the totally engaging plot.

Management effective worplace relationship Essay

Management effective worplace relationship - Essay Example This can lead to the third step in the relationship of mutual respect. A respecting relationship demands each person to contribute enough respect that it can be reciprocated back from the other person. Jose lack the skills of communication and hence his collogues don’t have real understanding and mutual respect. Unilateral respect in relationships is temporary and superficial. Mutual respect that can lead to trust is much deeper and must come from communicated understanding. Once a relationship has experienced mutual respect it is possible for the participants to experience enduring relational trust. This is a feeling that binds people together over time and through trials. The absence of trust causes confusion, worry, inaction and fear (Buzzle.com, 2006). Ans 2. Many of the problems that occur in an organization are the direct result of people failing to communicate. It leads to confusion and can cause a good plan to fail. Communication is one of the most key elements of leadership. Good communication skills need to be learned to effectively become a good leader or manager. When communication occurs, it becomes easy to accurately convey relevant operational information and thoughts to the team members. In this case Jose withheld some information and delayed giving other information to Jacinta and Toby because he thought that if the complete information is passed on he will not have any value. He lacked self confidence and lacked leadership skills. He also thought that by giving the information late (second day) he would be able to finish his part of work (all paper work), but he lacked the sense of proper time management. He should have thought that if he passes the information to Jacinta and Toby earlier than he does currently, simu ltaneously they could work and save a lot of time. When his team consists of people like

The process of learning is considerably simplified as the phonological differences or similarities between the first language and the second language become greater. Use of contrastive analysis hypothesis in the teaching of second language Inaccuracy of the learner’s language imparts the need for the teacher to ascertain if the error is related to pronunciation or grammar. In spite of all the controversies and critici sms that the use of contrastive analysis as a way of teaching second language has gained, many teachers still find the insights provided by the contrastive analysis hypothesis quite useful and helpful in comprehending the problems commonly faced by the students, and for making students understand what they need to learn.

This essay approves that grammatical errors that the learners of second language make can, in part, be attributed to interference between the first language and the second language. Nevertheless, at the phonological level, there is a certain level of reliability. Differences between other languages and English are often the major reason behind the interference. The process of learning is considerably simplified as the phonological differences or similarities between the first language and the second language become greater. This report makes a conclusion that the interaction hypothesis assumes the learner to be in a continuous cycle of learning. The quality and amount of learning is directly linked with the variety of experiences that the learner has in the everyday life. Learner in the eyes of interaction hypothesis is a person with receptive personality traits. The curiosity of learning is assumed to be ingrained in the learner. However, the quality of learning is fundamentally associated with the hold of the other person in communication with the learner over the second language of the learner. The learner might be able to learn more as a result of the interaction with another individual who is also a non-native speaker of the language in which the communication takes place because the learner can then identify with the communication partner and might thus be better able achieve hold over the weak areas. During the process of communication, the learner negotiates in the second language which reveals gaps in his/her abilities.

Musical Concert Summary Essay Example | Topics and Well Written Essays - 750 words

Musical Concert Summary - Essay Example My preference for music 'intelligent' music was the other but not minor factor. The concert took place at the Campus Center lobby, on Sunday, November 11 and was scheduled to start at 3:15pm. The Trombone Ensemble and Jazz band under the direction of Ronald Stitt presented a total of twelve pieces, with the Trombone Ensemble presenting three and the lively Jazz band the other nine. I arrived to find an almost packed Campus Center Lobby and was soon convinced that this concert was going to be good. The Trombone Ensemble comprising of retired Professor Emeritus of History, Jonathan Helmreich along with some students opened the evening with J.S Bach's "Chorale". As the soul stirring piece filled my being, I took in the intense yet relaxing ambience the melody had created. Clad in their black and white tuxedos, the Ensemble displayed great artistry and mastery of their instruments. The night reached a crescendo for me with the second piece, Mozart's' famous "Ave Verum Corpus". This was already my favorite Mozart work and the performance of the Ensemble was most breathtaking. They rounded up the first half of the concert with another good performance, the Hooper and Magliocco piece "So, You Wanna Play Trombone," After an interlude, the Allegheny College Jazz band opened with Carl Strommen's "The Opener", this lively start ensued for the rest of the performance as the Jazz Band continued with "I remember Clifford" by the soloist Mike Faix, Christina Dastolfo's "In the Wee Small Hours". The concert closed with a standing ovation after the performance of "Superstition", a Mike Tomaro piece. An encore performance of Mozart's "Ave Verum Corpus" was given by the Trombone Ensemble. Concert 2: Recital IV with Pianist Alec Chien My experience with Jazz band and the Trombone experience was rivaled by an earlier episode at Pianist Alec Chien's performance of Beethoven's 32 piano sonatas. The concert which took place at Allegheny College's Shafer Auditorium, was a sixth in a seven-concert series featuring, Chien who was Artist in Residence at Allegheny College. Professor Chien's demonstration of his mastery of Beethoven's work started a little after the pre-announced 7 pm, because the turnout had be underestimated and provisions had to be made to accommodate the eager guests. The last in the series of events is scheduled to be concluded with another free concert in the spring of 2008 at the same venue. The program started with Sonata Number 5 in C Minor, Opus 10 Number1; Chien standing briefly under the lights, bowed briefly before he sat, his delicate touch running through the keys as he concluded this number reminded me of my very first reaction to Beethoven's work; listening, hardly breathing and startled. Chien progressed with the Sonata No. 6 in F Major, Opus 10, No 2 and the Sonata No 7 in D Major, Opus 10, No 3. He delivered with pomp and a nostalgic finality Beethoven's last piano sonata, the Sonata No 32 in C Minor, Opus 111. Chien's performance was greeted by three standing ovations. The concert which was to celebrate Allegheny College family week, left me motivated, spirited and saddened. For me, Beethoven's Sonata's seemed to indicate a familiar despair prevalent in today's world. Chien himself seemed completely taken over by mixed emotions as he took a bow before the applauding audience. Overview The

Puppetry Theater In Pakistan Media Essay

Puppetry Theater In Pakistan Media Essay A couple of months back I attended the Karachi Literary festival, over there I saw puppeteers perform, a nostalgic feeling took over and reminded me of my childhood days when I enjoyed puppet shows with my parents at carnivals, birthday parties, entertainment in school and etc.In fact in primary school level it was almost necessary in our arts and craft class to make hand puppets with socks and develop stories and characters around them. I remember it being very popular even on television, characters like Uncle Sargam and the show Kalian were shown in the 90s on PTV.It was once a vibrant part of our popular culture but with the advent of technological changes, lack of funds and constant development this form of art and its popularity is retreating into darkness. In this dissertation I am going examine the rise and fall of theater puppetry in Pakistan with particular focus on reasons of decline of this industry in comparison to other countries in the subcontinent. I will provide an analysis of the downfall and the efforts of The Raafi Peer Theater to revive puppetry in Pakistan. Literature review: Puppetry captures the imagination and interest of young students and therefore used in many schools in the west and east as a medium to communicate and teach the children. Stories are told and retold through toys, gestures, animals and puppets using dramatic voices and theatrical effects. The popularity of puppets as a method for teaching can be traced for centuries. In the Flemish manuscript The Romance of Alexander, written in 1340, there is an illustration of glove pup- pets. Xenophon and Plutarch mention the use of marionettes. Medieval morality plays are performed by marionettes, and the pup- pets popularity is alluded to by Cervantes and Ben Jonson, Haydn, Mozart and Bach compose brief operas for marionettes in the wealthy court circles of the eighteenth century.  [1]   In Puppetry as an Educative Media Roberta Jane Confino reveals how puppetry can be transformed into an effective media by the educators today.Puppetery is often related to artwork and brings out the creativity in children as it mixes both memory with imagination, it seeks expression rather than true representation.  [2]  It becomes the educators responsibility to guide, encourage and build a rapport with child. The most important function of the teacher in an art room, and perhaps in every other school room also, is to create a creative atmosphere.  [3]   Puppets can be created from various objects such as finger puppets involve paper cut outs and material to fit over a child finger. Hand puppets involve movement of the entire hand with fingers and different areas. Shadow puppets are created when rod puppets are shown on a screen illuminated from behind. Marionettes, or string puppets may be simply worked with one or two strings or they may be made more complex.  [4]  Puppets may be made of materials found around the house or in nature. Painted branches or twisted scraps of wood are the beginning elements of characterization, paper-bag puppets, milk container puppets, puppets with simplistic design, and puppets with detailed color or features.  [5]  These puppets offer great opportunities for diversity, the possibilities are almost endless and Creativity and imagination can flourish  [6]   Technological advancements have also played a major role with animation and computer graphics. These days characters are made on the computer and shown on television catering to a larger audience. Steve Tillis in Art of puppetry in the Age of Media production questions if the figures made of the computer can be termed as puppets and if not what the reasons are for it. Is a person operating a puppet (tangible or virtual) in real-time is doing what puppeteers have always done; but a person working at a keyboard with a virtual puppet-despite the fact that one is controlling the movement of the puppet-does not seem to be engaged in the same activity, despite the fact that the result (i.e., movement of the figure) is the same.  [7]  One might say that the computer has freed the puppet from its dependence on conventional puppeteers, but computers have not freed the puppet from the necessity of human control of one sort or another. Steve Tillis brings the issue of tangibility as computer graphics figures are not tangible, they cannot be touched. However there are striking similarities in the creation of computer graphics figures and puppets: the creation of both involves the construction of a figure, in short, are artificial human constructs designed for manipulation (of one sort or another) by people.  [8]  Despite the similarities, I feel tangibility is a significant part that distinguishes the two. Puppets are as we have known them be thought of as tangible, while computer graphics figures are thought of as virtual puppets. The hands on experience of making the puppet, interacting with it, learning about it, integrating culture and history to it cannot be compared to a figure made on computer. There is a pleasure still to be found in the live performance of a tangible puppet, the direct confrontation between an audience and a living object that is distinct from the particular pleasures of media puppets. Rachel A.Bonney in her article on, Teaching Anthropology through folklore for the Anthropology Education Quarterly brings an anthropological view on the importance of folklore as an educational tool for children and the society as these stories hold value, cultural traditions that are passed on from one generation to the other. In this article Rachel A.Bonney focuses on how storytelling can be used for educational practices not only for children but at college level as well. She has been using this method for the past ten years as a teaching aid in both introductory and advanced anthropology classes.  [9]  She describes three separate uses of folklore: collecting folklore through fieldwork interviewing, analyzing themes in these stories and using folklore through puppetry and plays.  [10]  She points out how folktales are used as sources of information and insights on child-rearing and making them more aware of other cultures and on their morals, traditions and values. However, children are more familiar with their own culture and traditions than of others and therefore she used American or European cultures to analyze folklore material as it is easier and effective to identify and relate. For her study she used Grimms fairy tales such as Hansel and Gretel and Little Red Riding Hood because these two stories are popular in the American culture despite Medieval European origins and cultural change.  [11]  Furthermore she tells us how these stories are dramatized with puppet plays where students make their clothes, give them a face and make the surrounding that are illustrated to make it is culturally appropriate. They may range from stick puppets to socks, scraps of cloth, paper plates etc, and are often performed in a small scale setting and therefore it is cost effective.  [12]  Often additional sounds effects are used for example music, back vocals that are taped to enhance the dramatic presentation. Through background research for script writing students learn about another culture in depth, for example if the students were putting up a puppet show about Ali Baba and the forty thieves they would have to look in to the historical background, the roots of the charactors, what they wore in that time and so on. Rachel A.Bonneys argues that folklore might be seen as high tech in modern America, but her approaches have successfully shown us how Western and non-western values can be integrated to a childs bringing up not only in the literate society but as an effective device in non-literate society  [13]  . She further builds her argument by saying that anthropology is not exclusively an exotic and esoteric discipline for the study of primitive society. Anthropology is not for a few elite, but for everyone.  [14]   Her study on folklore tales is not restricted to the western world but also relatable here in the subcontinent. Much of the puppetry in the sub continent is associated with folklore stories based on historical themes. They hold great pride in their stories as they have been passed on from generations through oral history and have become a central part of identity of tradition and culture. Common folklores in the sub continent are of Heer Rahja,Sassi Pannu and Laila Majnu, these characters are recognized and referred to in their everyday lives. For example when someone is madly in love he will be referred to as Majnu not Shakespeares Romeo. Shakespeareans characters Romeo and Juliet represent undying love such is the case with Laila Majnu. Many additions and subtractions have been made to the story over the years but what remains constant is Majnus love for Laila. Puppets are portrayed differently around the sub continent for example in India they are popular in Tamil Nadu,Orrisa,Andhra Pradesh,Asaam and the West Bengal. They portrayed unique features of the art and are operated through strings attached to the knees, hips, wrists, shoulders that make each and every part of the body move in different directions just as humans do. This method is practiced till today. Thyagaraja Sharma, an English Professor, said that the art dated back to Indus Valley Civilization.  [15]  Excavations of clay dolls from the site were an indication of this long tradition. A lot of information about puppetry was seen in Sangam literature too. They are often religiously portrayed from epics like Mahabarata, Bhuddas life and Raamayana.Besides dealing with religious themes, Indian puppetry also conveys useful messages from Panchat`ntra and other mythological and historical epics.  [16]  Started initially as a medium of entertainment, puppetry became the media for propagation of ideas, dissemination of information, and educating the masses.  [17]   Anna Sobel, a professional puppeteer and an activist was intrigued by a show put up by the Indian puppeteers in the Smithsonian gallery in Washington DC.She spoke to them later and found out that they use puppets for social awareness programs such as AIDS in villages back home. In September she went to India on a nine month Fulbright grant to study Indian puppetry as a tool for social change in the primitive society.  [18]   In her article Mutual respect: Re-examining puppetry in India, Anna Sobel discusses how the uneducated class in India respond to puppetry and how their behavior changes because of it. As mentioned above India has a rich cultural association with puppets and with the help of government funding educational puppetry in not a foreign concept. The puppeteers took this responsibility as a moral obligation to the public which includes adults and children.  [19]  Sobel observed that the children in the village would get up early as four in the morning to practice and recite the story of Ramayana which they performed for forty one nights straight. They took this opportunity to provide extensive commentary on healing properties of local herbs and discussed educational themes.  [20]  She further observed how puppeteers were able to adapt a show to in the local ambiance much better than what she saw at the Smithsonian, as the audience recognized the stories, songs and characters. In addi tion, the live performance of the puppetry allowed direct rapport with the audience allowing them to be involved directly, the likely hood of them to remember the message more than if they saw the program on the television for example. Live shows are more common in the rural areas in India because they do not have access to mass media, such as television or newspaper. This may be the reason why in the cities puppetry is not common anymore as media has replaced this source of entertainment. However, the Indian government has still reinforced this craft because they use this as a tool for religious education. In Pakistan Rafi Peer theater workshop(RPTW) is one organization that has revived puppetry through theater,dance,music that has provided a rich cross cultural experience to audiences in Pakistan and abroad. In a country where accessing early childhood education is close to impossible, those who attend dropout at a early stage due to financial and family issues.RPTW is a non-government organization which is doing pioneering work in the field of Arts is run by the Peerzada family. Headed by Usmaan Peerzada, Faizaan Peerzada, Saadaan Peerzada, Imran Peerzada, Tasneem Peerzada and Salman Peerzada.It has built a Museum of Puppetry. It runs the Universal Child Art Foundation, promoting child art and visual learning globally. Presently it is developing a Theatre Arts training Institute. RPTW most important milestone is the establishment of the Museum of Puppetry in 2004.Till now it has organized over 25 international performing arts festivals. Festivals are one of the most popular attractions of cultural tourism, have been a part and parcel of South Asian culture for a long time. Pakistan Children Television (PCT) can be considered a landmark when it comes to educating children who lack formal education opportunities. Through PCT they started a show called,Sim Sim Hamara, an educational series of shows for children. It is a adaptation of Sesame Street has been created by RPTW in collaboration with the Sesame Workshop, New York, and funded by the United States Agency for International Development (USAID). The project is the outcome of extensive research as it includes participants from different provinces .They worked with the government and other educational experts so that they can cater to the educational needs for the children. This TV series was set to provide high-quality early education resource for a larger audience. Their goal is to educate families and children and the fact that learning can happen in formal and non-formals means. They use examples from the real world for example reading prayers from The Holy Quran, buying vegetables from the local market, attending school, how to communicate with other people, measuring ingredients for roti as a basis for storylines and materials.

Causes of the Behavior of Transgenic Mice :: essays research papers

Selectively manipulating genes can lead to a greater understanding of molecular and cellular brain functions and behaviors. However these specific gene mutations may trigger compensatory changes that mask a phenotype or adds to it. Therefore it might be difficult to determine the specific effect of a mutation on behavior. This is especially true since a mutation may be affected by the environment or a specific genetic background. Because of this it is important to find the best way to understand and interpret behavioral data. The Morris Swimming task is a task where the animals are encouraged to find a platform in a water tank. Through careful examination it was found that there where several behavioral trends. One of them is called thigmotaxis and it refers to the mice swimming near the wall without even trying to find the platform. This has to be overcome in order to achieve the goal. If it is not overcome then the stage where the animal learns the location of the platform cannot be reached. A generalized interpretation of the mutant animal’s behavior might lead us to believe that it cannot achieve its task because of learning and memory impairment however it can be observed that the reason for its failure might be its inability to overcome its initial behavior. To verify that this is the cause of the animal’s behavior there is a technique called PCA. This technique allows researchers t o correlate specific measures of the animal’s movements with various factors such as thigmotaxis to understand the specific causes of the behavior and how the mutation affects the animals. It has been found that 50% of the source of variation of the animal’s behavior is the inability to overcome thigmotaxis and is not related to its inability to perform learning tasks. To understand the specific effects of the mutation on animals one must also be careful to eliminate genetic background and environment as affecting performance. A Meta analysis of the data for the water task has shown that both environmental and genetic effect produce sufficient variation to account for the range of almost all behavioral measures. It is hard to determine the effects of the mutation alone without it being confused with effects from other sources. It is helpful to test inbred animals where heterozygous animals are mated to produce wild-type and homozygous offspring.

Performance appraisal Essay

Performance appraisal has been one of the most-debated management practices for several decades. It has generated a wide variety of viewpoints. There are those who see performance appraisal as making an important contribution to human resource management, in that organizations require systematic information on how well employees are performing in their jobs as a key element in ensuring that human resources are used as effectively as possible. Employees at all levels experience a need to know clearly what they should be doing and what is expected of them in terms of quantity and quality of output. In addition most people want to be in a position where they can perform better next time around. A number of writers, especially during the 1970s, expressed pessimistic views about the future of performance appraisal schemes, and the assumptions on which they are based. Some have tended to write off conventional versions of performance appraisal as backward, simplistic and even counterproductive, arguing that conventional appraisal processes often lead both the manager and employee to approach the performance review with dysfunctional role stereotypes. The employee expects to hear what is wrong with his or her performance, while the manger expects to have to well the evaluation to a reluctant and possibly hostile member of staff. (Gordon Anderson 1996) In this case study, it present the issues that caused Xerox Company emerged as a result of their research. In a word, it is all about change. It is talking about the linked issues of visibility and growth, and the compelling need for a process or model to deal with the problems of increasing effectiveness in the midst of all the change. I discuss changing attitudes and HRD political relevance, and present evidence of concern for HRD effectiveness. In Xerox appraisal new system they use â€Å"Mulit-appraisal† which is 360-degree Appraisal. The limitations of conventional performance appraisal in placing considerable, and sometimes total, emphasis on the judgment of the employee’s manager have been identified and discussed by a number of  writers. A pioneering study carried out a number of years ago in Gulf Oil, and described by Stinson and Stokes (1980), highlights an alternative, multi-rater method, which overcomes a number of the deficiencies of conventional, manager-orientated appraisal. Probably the most significant development likely to influence the nature of performance appraisal in the future is the shift away from conventional appraisals undertaken typically by line managers towards the concept of 360-degree appraisal. The concept builds on multi-appraisal and refers to a situation where appraisal data is collected † all around† an employee, from his or her manager, subordinates, peers and c ustomers, internal and external. A number of factors are encouraging organizations to introduce, or to seriously consider the introduction of, 360-degree appraisal. These include: ØFlatter, less hierarchical, more flexible, team-based organization structures; ØAwareness of the limited perspective of managers; ØRecognition of the value of contributions from other sources; ØThe advantage of a range of perspectives, given the increasingly complex roles many people play in organization. In research identified the need for building and maintaining close relationships with line and staff management as essential for a successful HRD organization. It is really depend on the organization and communication processes. A wide range of methods and criteria for appraising performance is used by organizations. The various ways of measuring performance stem directly form the different components of performance. We can see in the new system of Xerox, they are: Simple ranking, using this system the appraiser is called upon to make a judgment about the general level of the performance of each employee. Based on the appraiser ranks each employee from best to worst. Alternate ranking, this process involves a number of stages. While this approach may have some advantages in determining the ratings, it suffers from the same defects as the simple ranking approach. The HRD Function In effective HRD functions, staff development is built in to the annual operating plan as a requirement. It is not only supported by management, but also seen as essential to the continued effective operation of the HRD function, and adequate funding supports it. Another one is Feedback, It tells employees, â€Å"How am I doing?† and â€Å"Where do I go from here?† How would you like to be a member of a bowling team and go bowling every week, but only get your scores once a year? Coaching is the day-to-day effort to review work, answer questions, discuss progress (or lack of it) toward meeting standards, develop skills, and provide positive guidance. Is the supervisor the only person who can provide coaching to an employee? Coworkers, other supervisors, and even customers can often be in a good position to compare the employee’s performance to established standards and then give helpful feedback. As the articles shown that the core of any organization is its staff. Without workers, who is going to do the job? How come the goal is going to achieve? How effectively an organization maintains a quality team of employees is linked to its ability to manage its staff and recognize the contributions of each player. Effective performance management systems enable an organization to objectively and systematically rate employee performance, while providing the tools necessary to take that performance level and equate it to compensation actions. Employees have always expressed the desire for open feedback regarding their performance. More and more companies are embracing the pay for performance concept and its tie to compensation. A well-executive performance management plan enables an organization to achieve critical goals: ØRecognize the efforts and contributions of current staff ØReward staff with compensation directly linked to performance ØMotivate staff to improve performance ØOrient staff towards goal achievement ØRetain key employees through the use of competitive compensation programs ØAttract quality employees with an effective performance management system A necessary condition for the effective management of performance appraisal systems in any organization is the need to clarify and communicate to all concerned the objectives which the system is intended to achieve. Typically, performance appraisal schemes are expected to serve multiple objectives. This can often be strength in that several purposes can be achieved, but I can also prove to be a disadvantage if it leads to a dissipation of effort and lack of focus. It is obviously of crucial importance, and everyone in an organization especially the key decision makers should be fully aware precisely what objectives the system of performance appraisal is expected to achieve, and the priorities within these objects. Performance appraisal should lead to the identification of the training and development needs of employees. Indeed, it can be argued that without an appraisal scheme, it would be only accidental if training and development efforts were aimed in the right direction (Anderson 1980). Performance appraisal, by providing feedback to employees on job performance, creates a basis for improvement and development. The developmental function of appraisal is concerned with improving the performance of people by identifying areas for improvement, setting performance targets for the future, and agreeing plans for follow up action. This aspect also involves developing the capacity of people through formulation plans to develop their skills and careers, and helping individuals to reconcile their job and career aspirations with opportunities available in the organization. Furthermore, there is certain amount of overlap between the evaluative and development functions, in that the evaluation of past performance will often be an important influence upon the setting of future targets. Brinkerhoff  and Kanter (1980) contend that this function is both backward looking in the sense of evaluating past performance so as to establish standards and forward looking in that the established standards serve as incentives for future performance improvement through generating peer competition and the desire to best one’s won past record. The argue further that an additional overlapping, but also overarching, purpose for performance appraisal is to ensure that managers are performing a critical management function. Managers should be paying careful attention to the assessment of the past performance of their staff against organizational requirements, and to the development of greater productivity of the human resources available. This function of performance of performance appraisal of encouraging careful and systematic approaches in assessing the performance of employees is of great importance for practicing managers, and they often recognize its value. The possible conflict between the evaluative and developmental dimensions has been much discussed in the appraisal literature. The central issue appears to be: can the manager, acting as appraiser, effectively be both judge and helper without experiencing role conflict? Since future decisions must be based, at least in part, on evaluations of previous behavior, it could be argued that this conflict is superficial rather than real, and that an effective manager should be about to cope effectively with both roles. When we looked further at the issue of growth. The Conference Board, in a study of trends in corporate education and training, found that the number of training professionals had increased in nearly two-thirds of the firms surveyed. The board cited the following as evidence of the enhanced role and status of HRD in many companies: ØManagement has become convinced that education drives the business. ØA stepchild until recently, the training function is now seen as essential to the company’s strategic goals. ØDeveloping our people is now the heart of our business strategy. ØTraining departments used to be wiped out by recessions, but few were in the recent one (Lusterman, 1985, p.2). Affecting the growth of HRD is the increase in the overall number of jobs and the shifts from sectors such as manufacturing to service organizations. Newly created jobs require new skills training and workers being displaced need retraining. In addition, more workers are coming to expect training as part of the normal job environment, and will demand it if they don’t see it. This is especially true in high technology, where employees want to stay on the leading edge-they can’t afford not to. The negative factors are: ØPossible distortion due to popularity factors influencing peers; ØPossible negative reactions towards those who irrespective of this performance, are seen as unorthodox, inclined to challenge existing practices, and therefore perceived as threatening; ØFriendship rating; ØDistortions due to fear of retaliation; ØReliance of peers on stereotypes in making evaluation. Despite the risks evident from the number of possible negative factors, peer review may well have an increasing role to play in performance appraisal systems of the future, especially in non-hierarchical, team-based organizational structures in which peers are willing to give objective evaluations of one another’s performance, and where peers interact sufficiently frequently to be able to develop an informed view of the performance of colleagues. Conclusion Appraisal of employees tasks place whether a formal appraisal system is in operation or not. In small companies, formal systems are probably unnecessary; in larger companies, a formal system goes some way towards ensuring that decisions based upon judgments of employee performance are fair and just. However, the mere installation of an appraisal scheme does not ensure that appraisals are well founded. There are a large number of human tendencies towards error that must be recognized by those conducting appraisal. This recognition and ways to overcome the problems are best achieved through training. The appraisal of performance is useless unless the results of the appraisal are translated into action. This is the purpose of the appraisal interview. It is a mechanism for feedback of information to employees, and an opportunity for employees and their superiors to sit down and plan remedial action. Appraisal interviews involving problem solving, counseling and joint objective setting are essential components of a successful appraisal scheme. REFERENCE French,W.

Ice cream lab report essays

Ice cream lab report essays This experiment was about finding the fat content and molecules in foods that were chosen from our campus caf. The experiment concentrated mainly on macronutrients, which are the major sources for energy and include carbohydrates, lipids, and proteins. Lipids are needed for the formation of cell membranes, and proteins are needed as enzymes, receptors, and membrane transporters. Molecules may be either polar and stable in water or non-polar and avoid water. Also, in this experiment, micronutrients were involved and are used in the body for overall health and include vitamins and minerals. The procedures for this experiment were as follows: 1. Before entering the lab, students were asked to bring a food source into the lab from the caf to use for the experiment. Some foods were pre-prepared by Dr. Knight such as our food source, ice cream. Dr. Knight had already collected the food from the caf, weighed the food before any extractions or drying, and then put the food into a drying oven to prepare it for our lab. Our group then chose ice cream to conduct our experiment. 2. Our group then scraped out 8.00g of the dried ice cream to use to extract fat and oils into a mortar and pestle. Our group used to mortar and pestle to grind up the portion of the ice cream into a very fine substance. The sample of ice cream was then placed into a coffee filter and funnel and ether was used to wash what oils and fats we could away. This washing was done 3 times to ensure that all the oils and fats were removed. 3. After the washing was complete, the glass rod and mortar and pestle had some of the ice cream still left on it. To ensure that our calculations would be as accurate as possible, we then weighed the mortar and pestle and glass rod before cleaning and also weighed them after cleaning and used the difference to add to our sample. An empty coffee filter ...

Why Funding for Art Education is too Low essays

Why Funding for Art Education is too Low essays Why Funding for Art Education is too Low Many public schools have significantly reduced or completely cut funding for art education programs. Officials at state or city levels may feel the need for art education is not as significant as the need for more academic based programs like mathematics, history and science. Officials see art education as something that is impeding on their student's academic careers, rather than helping them flourish. Many who argue against funding arts education need to take a closer look at what art education does for a child. At a School Board meeting, Mr. Whyte (1996) first heard an argument against art education in schools: A well-dressed, well-spoken woman stood to complain that children graduating from schools were inadequately prepared to take their places in an ever more demanding labour market. Too many resources and too much instruction time, she maintained, were wasted on frills like music. Not enough attention was being paid to math and the sciences, computers, and technology, which she cited as the future keys to employability (p.13). The emphasis on academics is indeed important. Preparing students in certain subjects helps them achieve the standards set by school or government officials. Standardized testing has become the "golden rule" of school systems in the curriculum taught. Children are required to learn the curriculum and pass these tests in order to meet the standard of knowledge, or even to graduate. By funding these teaching methods and standardized tests, schools become accredited and therefore eligible to receive more funding for the school. The "real world" is not always composed of multiple choice questions, and rarely is there a certain right or wrong answer. Students who participate in art programs apply acquired thinking skills learned through art, to exceed in standardized testing as well as many other subjects in school, and life practices in genera...

The main goal is to provide an in-depth analysis of logistics services. A keen interest is on the way the logistics and maritime time related to economics which brings about the ocean transport business. It revolves around the focusing on the joint optimization of container terminals and liner shipping networks (Blecker & Kersten 2011). 4 Logistics in many contexts involves the delivery f goods and services with proper quality and quantity. Logistics depends on timely delivery and the destination of delivery. The most notable aspect of logistic is promptness of delivery because delay of any kind causes significant losses to the recipient of the consignment. Logistics traditionally depended on transportation only. Nowadays, it depends on reliable roads, and record keeping improved by higher technology, globalization, legislation, and integration. The logistics management comprises of material management, channel management, physical distribution, and it is pert of the whole supply chain management. Movement of goods is not the only logistics activities; it involves stock control in the warehousing systems and the movement of goods in the storage units (Martin 2009). Logistics forms a crucial area in supply chain and brings issues like planning, implementation, and effective management. 4 Many immerse growth activities realized in the logistics sector especially in the emerging economies. This shows a better future with third party providers. This growth realized in the area of logistics largely coming from third party providers such as

Humans Create Powerful Symbols - Hornbill Figure Essay

Humans Create Powerful Symbols - Hornbill Figure - Essay Example They also believed this entity allowed energy flow from one being to the next in a cyclic process. This connection between mankind and the rest of all living things inspired men to associate the image of nature to the theory of the existence of a higher being with supreme powers. These connections could be either supernatural or spiritual. This symbolic connection has been passed down through numerous generations throughout history. Different cultures and religions use the symbolism in the ways that are adapted to suit their beliefs. The specially skilled Ibans of Sarawak, whom are known for their carvings include an exclusively designed hornbill figure. This is an example of the combination of religion, nature, and art. The ‘Hornbill Figure,' known as 'Kenyalang,' has essentially been the chief subject of interest among the Iban carvers of Sarawak, Malaysia (Davenport). It was between the nineteenth and twentieth centuries that the Iban people began to show their culture by sc ulpting images of the hornbill. This also become a very important part of sacred ceremonies conducted by the Iban community. With a standard length of over 33 feet, the Hornbill Figure is traditionally created using wood, paint, cotton thread, plant, and wool materials and textiles. At the Fowler Museum, a person can take in the details of the art form of the hornbill sculpture. Its sharply pointed bill draws a huge curve and the painting on the body uses various strokes and pigments portraying how colorful the Iban festivals and culture are. Hornbill carvings are recognized as an art form but also is an indicator of the way of life of the Iban people. The unique portrayal of the carvings are associated with Iban’s greatest festive celebrations with religious rituals (Davenport). The Hornbill Figure typically is a special embodiment of a bird believed to possess knowledge and wisdom. Aside from bringing a prophecy to which Iban communities deeply relied on in the past, it is also considered a fundamental medium. This allowed for the blending of a spiritual dimension with the world of humans so they may possibly pass on their freedom to interact with spirits and supernatural beings for many reasons (Davenport). To achieve victory during war, the hornbill symbol and faith in its image was believed in to help aid in obtaining extraordinary power to intimidate and eventually subdue enemies. In particular, the custom of Iban’s Gawai Kenyalang had such strong meaning that it was used for the purpose of reaching success in raiding and headhunting (trophy-taking). During this, the heads taken from the enemies were claimed to have powers that could potentially add to the overall strength or invincibility of the victorious community (Davenport). Looking at the figure of the hornbill and evaluating the different features, one can feel the depth of the strong Malaysian history and culture. There is an aesthetic feeling that is brought out in its design that is highly representative of the culture of its people. Regardless of the complex processes of politics and the changes of culture for the Iban people through history that has impacted their lifestyles in several ways, the Ibans still believe in the hornbill image. The carved figure of the bird reflects the symbolism of courage and power of the Iban people. The artist takes the approach of providing exquisite carving as well as adding vibrant colors. The bird's eyes contain an intense yet subtle look. Unlike other icons of religion, the Hornbill Figure is more influential than many other types of symbols. This in turn makes the believers in its powers very strong. As the making of hornbill images increased
