Public Relations - Essay Example Corporate social responsibility will always be given the emphasis that it richly deserves because it makes or breaks an organization in the sheer sense of the word1. To start with, public relations aim to focus on the aspect of building credibility for the sake of the organization in the eyes of the publics so that they can think, act and feel positive about the organization, the individual or an entity for that matter. The public relations are usually given importance because the organizations know that they will be able to derive a great amount of mileage from the intended publics as they aim to touch upon new avenues and explore the novel pathways upon which these publics can be reached in essence. What is most important is the fact that ethical manifestations start making the rounds of the discussions which center on the premise of public relations and the related corporate social responsibility2. ... Since public relations are all about understanding how the organization should be viewed by the public in terms of its important dealings, it will never afford to have a negative word about its own self. The role of public relations within the corporate social responsibility ranks is all the more necessary to gain an insight from. This is because public relations have always been forthright about the organization’s corrective stance no matter how difficult it is to reveal to the varied publics. This gains importance with the changing times since people are now properly realizing how they must be treated at the hands of these organizations and what kind of attitudes rule the roost at the end of the day. Public relations will always assist in building up a corporate social responsibility understanding as it takes care of the problems which arise every now and then, and assures one of complete responsibility and commitment to an organizational cause. The role of the public relati ons at improving and enhancing the levels of corporate social responsibility should be such that there is empathy within the related ranks, and this shall mean success for the organizations in the long run. If corporate social responsibility understandings are properly managed, then this would immense success for the organization because these are run parallel with the public relations domains4. The management regimes of the organizations always look at addressing the grey areas so that these weaknesses could be plugged and turned into strengths in a very free flowing manner5. Since the corporate social responsibility measures take care of the ethical look of the organization and thus it creates harmony amongst the aegis of the organization, it would always

People in the film Essay Example for Free

People in the film Essay The creation of the monster involves the use of gadgets. The storm detector was needed to show when to lift the monster on to the roof. After lifting the monster up onto the table and elevating it up through a hole in the roof. It was then shocked by lightning, to bring it to life. The table the monster is position on in the centre of the room this is to put emphasis on him and to show that this is the most important aspect of the film. Dr Frankenstein brings the monster to life. A low angle is used on the monster to make him look big and scary, this is created due to the bold features of the monster. A low angle, which gives the effect that, the audience are actually watching the table rise. A tracking angle is used to follow the monster up onto the roof but when the table is on the roof a low is used, we cant see what is happening on the roof, this creates unpredictability, which creates suspense and tension. The lighting is used on the monster, this is used to define the bold features of the face, and this lighting is low lighting. The people appear shocked, amazed and scared as if they dont know what is happening, this influences the audience to feel the same way also this makes the audience feel insecure also because the camera angles and sound draw us into the film it makes the audience feel the same emotion as the people in the film. When the creature moves its hand a close up shot is used, this is to show that the monster is alive. When this happens the sound effects get louder, this is to increase the tension and suspense. The Dr Frankenstein shouts hes alive, its alive, he then shakes around and he is restrained as if he was mad, this creates more tension due to Dr Frankensteins unpredictability and this scares the audience. In the novel we are slowly set into the scene but in the movie we are straight into the storyline this is due to that it would be boring if we were slowly set into the scene also this is a horror movie so there should be no moments where there isnt tension. In the novel and the movie there are differences this is because there are only certain things that you can do with a book but in a film you can do more for e.g. in a film you have sounds and you can have camera angles to add to suspense and tension. In the novel Dr Frankenstein doubts what he is doing (a moral dilemma) but in the film he is very excited by what he was doing. In the book Frankensteins room is described as a small candle lit room but in the movie it is a big tall room with high tech equipment. In the novel Dr Frankenstein is not evil and the monster is not really evil but in the film Dr Frankenstein and the monster are perceived as evil. This is because the film is a horror movie. In the novel there are less gadgets (if any) described but in the movie there are many gadgets this is because in a movie the audience want to shocked amazed and interested, these gadgets do all of these things. In the film Frankenstein is perceived as a loner but in the novel he has a loving family and background. This is because if Frankenstein came from a loving family we couldnt see Dr Frankenstein as evil and evil is needed to create a good horror movie. In the novel, he doesnt have an assistant but in the film he does. In the novel the monster is created without anybody there but in the movie there are witnesses to his creation, this is because in the film the director wanted to involve the audience, which makes them scared. James Whale needs to create tension, suspense, and unpredictability to create a good horror movie. He did this by using different lighting and camera angles. He used certain camera angles to put us into the scene such as p.o.v and long shot, this shows where things are and shows whats happening in a certain areas. He used some shots for emphasis such as close up and extreme close up; this draws your attention towards something so that you notice it. Some of the shots he used were to involve us in the scene such as low angle, rolling shot, tracking this is to make us more scared because it makes us sense what we are seeing so therefore its makes us feel mise-en-scene. The lighting that James Whale uses is under lighting, filler lighting and there is flashes of lightning these are all used to create suspense from the same building in different ways.

Behaviorism Essay -- Behavior Psychology Psychological Essays

Behaviorism Psychology is the science of behavior. Psychology is not the science of the mind. Behavior can be described and explained without making reference to mental events or to internal psychological processes. The sources of behavior are external (in the environment), not internal (in the mind). Behaviorism is a doctrine, or a set of doctrines, about human and nonhuman animal behavior. An important component of many psychological theories in the late nineteenth century were introspection, the study of the mind by analysis of one's own thought processes. It was in reaction to this trend that behaviorism arose, claiming that the causes of behavior need not be sought in the depths of the mind but could be observed in the immediate environment, in stimuli that elicited, reinforced, and punished certain responses. The explanation, in other words, lay in learning, the process whereby behavior changes in response to the environment. It wasn’t until the twentieth century that the scientist began to uncover the actual mechanism of learning, thereby laying the theoretical foundation for behaviorism. The contributions of four particular scientists are Ivan Pavlov, John B. Watson, Edward Lee Thorndike, and B.F. Skinner. A Russian neurophysiologist, named Ivan Pavlov (1849-1936), found that if he consistently sounded a tone at the same time that he gave a dog food, the dog would eventually salivate to the sound of the tone alert. Through this research he discovered a basic mechanism of learning called the Conditioned Reflex. A Conditioned Reflex is if a neutral stimulus (i.e. the tone) is paired with a nonneutral stimulus (i.e. the food), the organism will eventually respond to the neutral stimulus as it does to the nonneutral stimulus. Perhaps the strongest application of classical conditioning involves emotion. Common experience and careful research both confirm that human emotion conditions very rapidly and easily. Particularly when the emotion is intensely felt or negative in direction, it will condition quickly. His findings raised the possibility that many of our responses, like those of the dogs, were the result of a simple learning process. In other words, our loves and hates, our tastes and distastes might be the consequences of nothing more mysterious that a conditioning process whereby various things in our environment became "linked" in our min... ...lly "spreads," or generalizes, to thinks that resemble the conditioned stimulus. An example to this is in Watson's experiment with little Albert's spontaneous fear of rabbits, and other animals that resembles a white rate. The opposite side of the coin from generalization is discrimination that is learning to distinguish among similar stimuli and to respond only to the appropriate one. People learn to discriminate between similar stimuli, between a friendly smile and a malicious grin. When one turns to have reinforcing consequences and the other does not. When I was a little boy I loved the ice cream man. There would be so much noise going up and down my block but I could always hear his music over all the noise. Shaping is a critical process to operant conditioning. Throughout this process there is a positive reinforcement of successive approximations. The basic assumptions of behaviorism are that psychology's task is to study behavior, or the responses an organism makes to the stimuli in its environment; that psychological research should be empirical, based on measurement; that behavior can be controlled and predicted, and that the major component of behavior is learning.

Biography of Edgar Allan Poe Essay example -- Biographies Edgar Allan

Biography of Edgar Allan Poe Many authors' literary works are often influenced by their own personal life experiences. Among these authors is Edgar Allan Poe, one of the most inventive writers of prose and poetry in the nineteenth century. The juxtaposition of Poe's life and work is most evident in the morbid personalities and melancholy themes of his literary compositions, similar to those of his life. Edgar Allan Poe was born in Boston, Massachusetts on January 19, 1809. His mother, Elizabeth Arnold Poe, had been widowed at eighteen, and two years after his birth she died of tuberculosis at the age of twenty-four. Poe's paternal grandfather had been a wealthy man, but his father, David Poe, had left the family to become an actor, and Edgar was left with nothing. When his mother died, John Allan, a Richmond tobacco merchant, at the urging of his wife, Frances Allan, adopted Edgar. She was devoted to Edgar, and in his childhood he enjoyed a security that was never to be his again after he left home. In 1815 John Allan took the family to England in the hope of furthering his business. During the next five years Edgar attended various schools, the most significant of which was the Manor House School at Stoke Newington. The gothic atmosphere of this school provided him with many details he was later to make use of in his fiction. He wrote about his impressions of the London school in a story called "William Wilson". (Meyers, 1992, p.12). During the fall of 1823, when Edgar was fourteen years old, his classmate Robert Stanard introduced Poe to his mother, Jane Stanard, who was a beautiful and compassionate young woman. Edgar became devoted to her. He called her Helen, which to his ears sounded far more... ...7, 1849, at 5:00am. (Meyers, 1992, p.254-255). Edgar Allan Poe's deplorable life was filled with unfortunate calamity, endless tragedies, and pathetic misery, which inevitably led to his pessimistic view on life and obsession with death. His personal mind frame is automatically conveyed in his essays, which for him was a primary form of expression. Thus, a strong emphasis on somber despondency has proven to be a thematic element of his literary career. Bibliography: Works Cited Krutch, Joseph Wood. Edgar Allan Poe. New York: Alfred A.

Reflection Paper. Reflection PaperIntroduction Hinduism and Christianity are religions that have existed in the world for a very long time now. Each of the religions have many followers depending on the area of presence Hinduism is a religion that is commonly known as Sanatana Dharma meaning eternal religion and Varnasramadharma which emphasizes the fulfillment of duties and responsibilities that are prescribed by both the class and the stage that one is in. It is the perennial faith for the Hindus. It is one of the oldest among the religions that are practiced in the world and still is today amidst the dharma faith. This paper discusses the distinctive aspects, similarities and differences of the two religions. Discussion Hinduism is characterized and comprised of a diverse array of beliefs, scriptures and practice system. It originated from the ancient Vedic culture back in 2000 BC. It is estimated to be the third world largest religion in the world having about 940 million people. 96 percent of these people reside in Indian subcontinent. If the yoga followers are included the religion carries about 1.05 billion people in the whole world (Dogra and Dogra, 2003). It has neither traceable founder nor a date when it originated. The authors and the dates of the sacred texts of the Hinduism religion are unknown. Hinduism is not a homogenous organized religion. Most of its followers are committed followers of Shiva whom they look at as the only true God. Others refer in ward to the divine self that is called atman. Most of its followers identify the existence of Brahman as the unifying factor and the reality responsible for all that lives.   Hinduism religion is thought to have its name originating from the Persian word Hindu which means river. It was used by outsiders to refer to people of the Indus river valley. Hindu practice distinguishes itself from other religions by encouraging its followers to be tolerant to other people with different beliefs. This is because the religion posits that temporal systems cannot assert solitary understanding of one transcendental truth (Hawley and Narayanan, 2006). The followers respect the Brahmans and the Vedas while some others consider only one of the two authorities. The religious life of its followers is devoted to God or gods, meditation and duties of the family life. The first sacred writings of Hinduism were mostly about the ritual sacrifices to numerous gods who acted as representatives of the forces of nature. After the development of the Vedanta philosophy, new belief and custom systems came up from Hinduism forming Buddhism and Jainism. The Hinduism tolerance to diversity in belief made it acceptable to many persons in the west as an alternative to most the religion in the west. Although Hinduism got a relatively few converts from the west, its thought and practice influenced the west indirectly as seen in the development of new religions such as the hare Krishna and new age. Indian beliefs and practices such as the chakra and the yoga system were incorporated in books that covered health and spiritual issues. The Hindu followers worship in the temple. Christianity has been defined as a monotheistic set of values and practices that are primarily based on the Old Testament and the wisdom of Jesus Christ as brought out in the New Testament.The Christian religion is monotheistic in nature. It has its belief in one God who created the entire earth and all that is in it.   Different groups of people that support Christianity place different weight on the three issues but they all put their beliefs in them. The Christian religion is divided into two groups; the Catholics and the Protestants. Christians believe in the holy trinity that is comprised of God the Father, God the Son and God the Holy Spirit. The followers of the Christian faith believe that the three are contained in one God almighty. Followers of the Christian religion worship in the church. Christians consider that man was created in the likeness of God. Those human beings are both physical and spiritual beings who are rational, are able to establish relationships with one another and are capable of making wise decisions (Bainton, 2000). Christianity bases its belief on Jesus Christ. That he is the son of God who was sent to the world to come and save the human kind from sin and their inequities to the righteousness and love of God. That he descended died, resurrected and ascended in to heaven where God is. It emphasizes on the free conscience of a free person in a free community. Christianity is not just bout morality. It is about repentance and the relationship with Jesus Christ as man`s savior. The three most significant features of Christianity encompass the axial role of human freedom of serving their God. People are allowed to make willingly their choices about servitude. Secondly, that man should devout things that belong to God to Him. This is clearly shown in Ceaser`s story in the bible.   That all things that belong to God Should be given unto Him. Thirdly, the recognition that man often does what he is not supposed to do and do not do the things that he is supposed to do. This is manifested as sins that are supposed to be repented for so that God may have mercy and forgive the sinners. What should be clear is the unity of humanity as reality and persistence of differences without which permanent and deep unity and affection could not be there. Hinduism and Christianity share some form of similarity. The goals that are brought out from the two religions are alike. This touches more on issues of after life, heaven, and the goodness that people should display. Both the two religions encourage people to do good while on earth so that after their death they may go to heaven. It however they engage in bad deeds they will go to hell where there is suffering.   The believers of the two religions are supposed to be perfect on their spiritual lives. This is seen in Hinduism Moksha and Christianity`s heaven.   Christianity teaches about the teachings of Jesus Christ regarding the goodness as a means of measuring right and wrong. This is the same with Hinduism teachings on karma. The two religions both teach about soul and sin cleansing with emphasis on water. Christianity has its belief in the holy trinity that is encompass of God the father, God the son and God the Holy Spirit. Hinduism has a similar belief in the role and responsibility of its many gods.   Hinduism has three primary gods that some Hindus believe work as one in Brahman. Most Hindus believe that all gods and goddesses work as absolute reality referred to as Clemmons. In Christian churches there is always water at every entrance to bless persons with the love of God and to be cleansed before getting into the church. In Hinduism worshippers cleanse in communal baths before getting to the temples for prayer. Hinduism talks about Maya and atman which corresponds to Christianity concepts of grace and sin. These aspects are linked to the relationship of Christians with the coming of Jesus Christ to the world and Brahman on the part of Hindus. Despite having similarities, Hinduism and Christianity have differences. Hinduism recognizes Christianity as a valid religion with the same goal like its own. Hinduism considers all other religions as different ways that lead to the same end unlike Christianity that does not consider any other religion as valid. This is brought clearly through the teachings of Jesus Christ that state that no one will enter in heaven except through him, the way, truth and life. The eventual Hinduism ideal is mysticism which is basically a matter of intellect, consciousness and intuitiveness. Christianity on the other hand encourages sanctity which has to do with God`s will and love (Caldwell, 2010).   Eastern religions Hinduism being one of them are understandable from within only by the few people who share the understanding which makes Hinduism esoteric. It has many levels of truth comprising of sacred cows, reincarnation and monism. Western religions, Christianity being a party are exoteric, democratic and open to everyone. Hinduism is a religion that is evolving. It has no known founder unlike Christianity that has Jesus Christ as its central entity. Hinduism has no exact time that it started or was founded. Hindus believe that everything is part of God whether right or wrong and thus to them God is manifested in both good and evil. Christians on their side consider that God did not create evil but instead gave man   a free will to exercise what he feels good for himself but with a price to pay. Conclusion Hinduism as an eastern religion and Christianity as a western religion have distinctive features that make them stands out from each other. The two religions have some similarities that link them together as well as differences that clearly separate them. Even though they have differences and similarities, Hinduism exists in the west just like Christianity exists in the east. It is only that they are minimally established in those areas. The two religions have existed in the world for over two thousand years and will still be there in the coming years. References Dogra, R. C. Dogra, U. (2003).

Understand What Normality Means in Chemistry

Understand What Normality Means in Chemistry Normality is a measure of concentration equal to the gram equivalent weight per liter of solution. Gram equivalent weight is the measure of the reactive capacity of a molecule.  The solutes role in the reaction determines the solutions normality. Normality is also known as the equivalent concentration of a solution. Normality Equation Normality (N) is the molar concentration ci divided by an equivalence factor feq: N ci / feq Another common equation is normality (N) equal to the gram equivalent weight divided by liters of solution: N gram equivalent weight / liters of solution (often expressed in g/L) or it may be the molarity multiplied by the number of equivalents: N molarity  x equivalents Units of Normality The capital letter N is used to indicate concentration in terms of normality. It may also be expressed as eq/L (equivalent per liter) or meq/L (milliequivalent per liter of 0.001 N, typically reserved for medical reporting). Examples of Normality For acid reactions, a 1 M H2SO4 solution will have a normality (N) of 2 N because 2 moles of H ions are present per liter of solution.For sulfide precipitation reactions, where the SO4- ion is the important part, the same 1 M H2SO4 solution will have a normality of 1 N. Example Problem Find the normality of 0.1  M H2SO4 (sulfuric acid) for the reaction: H2SO4 2 NaOH → Na2SO4 2 H2O According to the equation, 2 moles of H ions (2 equivalents) from sulfuric acid react with sodium hydroxide (NaOH) to form sodium sulfate (Na2SO4) and water. Using the equation: N molarity x equivalentsN 0.1 x 2N 0.2 N Dont be confused by the number of moles of sodium hydroxide and water in the equation. Since youve been given the molarity of the acid, you dont need the additional information. All you need to figure out are how many moles of hydrogen ions are participating in the reaction. Since sulfuric acid is a strong acid, you know it completely dissociates into its ions. Potential Issues Using N for Concentration Although normality is a useful unit of concentration, it cant be used for all situations because its value depends on an equivalence factor that can change based on the type of chemical reaction of interest. As an example, a solution of magnesium chloride (MgCl2) may be 1 N for the Mg2 ion, yet 2 N for the Cl- ion. While N is a good unit to know, its not used as much as molarity or molality in actual lab work. It has value for acid-base titrations, precipitation reactions, and redox reactions. In acid-base reactions and precipitation reactions, 1/feq is an integer value. In redox reactions, 1/feq may be a fraction.
