Branding and brand management Essay

What is a brand? A brand is a name, term, sign, symbol, or design, or a combination of them, intended to identify the goods or services of one seller or group of sellers and to differentiate them form those of competitors Essentially a marketer’s promise is to deliver a specific set of features, benefits and services consistently to the buyers Cadbury’s best tasting chocolate constitutes the main ingredient of much of these products including everything from solid blocks to chocolate filled bars and novelties The Cadbury brand is associated with best tasting chocolate Marketing managers at Cadbury are working to ensure this association is continually developed. Key concepts of quality, taste and emotion underpin the Cadbury brand. These core values help to differentiate Cadbury from other brands and ensure its competitive advantage A brand is a complex symbol that can convey up to six levels of meaning 1. Attributes – a brand brings to mind certain attributes – Cherry Ripe – ripe juicy cherries and moist coconut smothered in rich ‘Old Gold’ Dark Chocolate – Crunchie – golden honeycomb smothered in Cadbury ‘Dairy Milk’ Milk Chocolate – Flake – unique, delicate strands of crumbly, flaky Cadbury ‘Dairy Milk’ chocolate – Picnic – combine delicate fingers of crisp wafers, temptation of chewy caramel with goodness of rice crisps, all generously encased in Cadbury chocolate – Roses – delicious mix of Milk and Dark chocolates, ideal token gesture for any occasion – Dairy Milk – the goodness of a glass and a half of rich full cream milk in every 200g, Australia’s favourite chocolate 2. Benefits – each brand’s attributes must be translated into functional and emotional benefits to the consumer 3. Values – Cadbury’s mission statement says simply: ‘Cadbury means quality’; this is our promise. Our reputation is built upon quality; our commitment to continuous improvement will ensure that our promise is delivered’ 4. Culture – For many people, chocolate is Cadbury, and no other brand will do 5. Personality – taste, colour purple and the glass and a half symbol all all hallmarks of Cadbury personality 6. Users – the kind of consumer or who buys or uses the product. Loyal customers are the most valuable customers to have because they will buy your product over and over again Brand equity – Brands vary in the amount of power and value they have in the marketplace – Brand equity is an asset – Cadbury brand equity is highly differentiated from other brands with consumers. Brand equity is the value consumer loyalty brings to a brand, and reflects the likelihood that a consumer will repeat purchase. This is a major source of competitive advantage. Brand name decisions – Manufacturers and service companies who brand their products must choose which brand names to use – Cadbury brands include the Corporate name combined with individual names – The company name legitimises, and the individual name individualises the new product – A suitable name, must be chosen and registered; it must be unique to the product and in today’s business arena, it should be capable of international use. Careful checks must be made to ensure that the selected name does not mean something different in other languages Brand-building tools Amongst the most important tools for attracting attention to Cadbury brands are: – Public relations and press releases – brands can gain a lot of attention from well-placed newspaper and magazine stories. – Sponsorships – brands are frequently promoted in sponsored events. Cadbury sponsor the Melbourne Cup Carnival, the animal nursery’ at the Royal Show, and the three time AFL premiership champion Brisbane Lions – Factory visits – Cadbury have factory tours in which they invite visitors to spend the day at their Claremont factory in Tasmania – Event marketing – product launches – Social cause marketing – some of the projects that Cadbury support are the Students In Free Enterprise, Foodbank and the Variety Club Brand strategy decision Generally a company’s brand strategy varies depending on whether the brand is a functional brand, image brand or an experimental brand – functional brands – are purchased to satisfy a functional need such as immediate eat i.e. chocolate bars – image brands – arise with products or services that are difficult to differentiate, or to assess quality, or convey a statement about the user – experimental brands – involve the consumer beyond simply acquiring the product Over time, each type of brand can be developed further. A company can introduce line extensions (existing brand name extended to new sizes or flavours), brand extensions (new brand names in existing product categories), multibrands (new brand names introduced into same product category), new brands (new brand name for a new category product) and co-branding (combining two or more brand names) Brand auditing and positioning Cadbury need to periodically audit their brands’ strengths and weaknesses It will occasionally discover that it may have to reposition the brand because of changing customer preferences What are Cadbury’s key brands? The Cadbury Dairy Milk block is the company’s flagship brand There are many other favourites including Fruit & Nut and Hazel Nut, as well as popular cream filled products such as Snack and Caramello Cadbury produces a variety of boxed chocolate assortments, most notably Milk Tray and Roses. Children’s lines include Australia’s long time favourites Freddo Frog and Caramello Koala. Famous Cadbury chocolate bar lines such as Cherry Ripe, Picnic, Flake and Crunchie also feature amongst Cadbury brands Are there different brands for different target markets? The Cadbury brand has a profound impact on individual product brands. Brands have individual personalities aimed at specific target markets for specific needs e.g. TimeOut, for example, is an ideal snack to have with a cup of tea Consumers know they can trust a chocolate bar that carries Cadbury branding The relationship between Cadbury and individual brands is symbiotic with some brands benefiting more from the Cadbury relationship, i.e. pure chocolate brands such as Dairy Milk. Other brands have a more distant relationship, as the consumer motivation to purchase is ingredients other than chocolate, e.g. Crunchie. Cadbury has identified brand values and adjusts its advertising strategies to reflect these values in different markets. Its strategy can vary from increasing brand awareness, educating potential customers about a new product, increasing seasonal purchases, or as is currently the case in the ‘Go Another Cadbury’ campaign to highlight the positive emotional value of the brand. How are the brand images related to Cadbury’s overall positioning in the market? Customers come to know a brand through a range of contacts and touch points, particularly trough word of mouth, personal observation and use, and images through advertising and promotion The ‘taste’ of Cadbury’s chocolate has long been the focus of Cadbury’s advertising. This has been supported by the slogan ‘a glass and a half of full cream milk in every 200 grams’, accompanied by a picture of milk pouring into the Cadbury’s Dairy Milk chocolate block. This was a tremendous advertising coup and has served the brand well for over 50 years. The image has become an integral part of the packaging design and has been featured in magazines, and on buses and trains, billboards, and television Cadbury’s unshakable dedication to tradition and philosophy of using only the finest quality of ingredients and finest quality goods help to position it not only in Australia but all over the world Cadbury has established itself as a company of fairness and integrity, which always attempts to operate as a socially responsible business The choice to support and sponsor certain events and organizations alos shapes these images References: Kotler, P 2003, Marketing Management, 11th edition, Pearson Education, NJ, USA Cadbury, http://www.cadbury.com.au, http://www.cadbury.co.uk, http://www.cadburyschweppes.com Cadbury Head Office, The story of Cadbury and Chocolate Making, Port Road, Hindmarsh, SA Gain Report #AS2042, Australian Product Brief Confectionery Products 2002, Australian Centre for Retail Studies

Psychologists’ Participation in Military Interrogatory Operations Essay

The issue of ethical responsibility is always in question especially in the medical and allied medical fields. The article â€Å"Psychologists Clash on Aiding Interrogations† (Carey, 2008) tackles this issue in the context of the services rendered by psychologists to military operations involving the interrogation of detainees. The article points out certain details regarding this issue; among others, those tackled were the issue of this type of assistance and its relevance to the American Psychologists’ Association Code of ethics, the consideration of international laws in the performance of a psychologist’s duties, the ethical responsibilities of a psychologist to the person being interrogated, the relationship of the APA to the practice of its members, and the individual integrity of psychologists who chose to collaborate with the military in interrogatory operations. An initial approach to this issue would be to consider the role of psychologists in society in the context or professionalism. Base on the preamble of the APA Code of conduct, psychologists are â€Å"committed to increasing scientific and professional knowledge of behavior and people’s understanding of themselves and others and to the use of such knowledge to improve the condition of individuals, organizations, and society† (APA, 1992), in addition, psychologist should â€Å"respect and protect civil and human rights and the central importance of freedom of inquiry and expression in research, teaching, and publication. They strive to help the public in developing informed judgments and choices concerning human behavior. † (APA, 1992) Certain features can be easily gleaned from these APA passages; to note in particular are the psychologist’s roles in the development of academic knowledge in the field, the fostering of individual and social understanding, and in promoting and preserving individual, organizational, (your family name) 3 and social welfare. Over and above these professional roles are the particular attention given to civil and human rights and the freedom of inquiry and expression. In this context there is no argument as to whether the psychological profession in general should concede to working with the military in interrogatory operations – the mere fact that these interrogations do not serve the purposes of the profession as outlined above and may even be violations of certain civil and human rights simply shows that participating in military interrogations can be against the APA code of ethics. However, if the last part of the passage is considered, which concerns the preservation of individual, organization, and social welfare, psychologist participation in interrogations may actually serve this end. If the purpose of the military interrogation is to preserve the established order and the issue is national security, then psychologists being accountable, not only to their patients but also to their country, should do well by assisting the military in their operations. This is the argument put out by certain psychologists who have been found to be collaborating with the military – that they did not do anything to cause harm to any of the subjects of interrogation, rather, they merely ensured that the subjects were not caused any harm. In addition, they claimed to also be performing their duties to their country. Another perspective should be considered in this issue – the reports that have been going around that psychologists have been assisting the â€Å"CIA and the military in developing abusive interrogation techniques used on terrorist suspects† (Benjamin, 2007), that psychologists have collaborated with the military in the military’s secretive Survival, Evasion, Resistance and Escape program to â€Å"reverse-engineer† techniques originally designed to train U. S. soldiers to resist torture if captured, by exposing them to brutal treatment. † (Benjamin, 2007). These grim (your family name) 4 reports bring the issue of civil and human rights into the picture. In a profession that is easily abused as to its practice, civil and human rights should be protected at all costs, but what if those who are supposed to protect these rights are the ones violating the rights themselves? The military and psychology is a very unlikely and dangerous mix, with the former working for national security under the protection of national and international law, and the latter working for the advancement of the psychological profession which incidentally could be of valuable use to the military, and with only the APA Code of Ethics standing in the way, possibilities can be very scary – think Nazi concentration camp style. However, certain arguments point out that psychologists, like their military counterparts are able to set aside the APA Code of Ethics in the interest of national or international law. In the results of a 20025 APA Taskforce, it was implicitly implied that â€Å"psychologists can ignore their ethical code if a governing authority (in this case, the U. S. Military) asks them to do so. † (Reiss, 2007) This implication is based on no less than the the APA’s code of conduct, which states, in full, â€Å"If psychologists’ ethical responsibilities conflict with law, regulations, or other governing legal authority, psychologists make known their commitment to the Ethics Code and take steps to resolve the conflict. If the conflict is unresolvable via such means, psychologists may adhere to the requirements of the law, regulations, or other governing legal authority. † (APA, 1992) This brings the issue to a whole new level – instead of the issue being an organizational or professional concern, it becomes a concern of individual integrity, which, by the way, becomes blurry when an individual is offered lucrative benefits and perks in exchange for that (your family name) 5 integrity. While the issue is obviously one that concerns not only the military, or the field of psychology, but the safety and welfare of even the most hostile subject of an interrogation, the APA Task Force served to bring the issue down to a more personal level to dismiss whatever argument is raised by the profession as a whole. Now, it is basically a question of, â€Å"As a psychologist, are you personally inclined to assist the military in their interrogatory operations even when these operations can be inhumane and can violate civil and human rights as long as the operations are within the â€Å"requirements of the law, regulations, or other governing legal authority† (APA, 1992)? † Many a psychologist would find an easy answer to this question, because this question does not require a psychologist to consult any code of ethics or any law; it simply requires that the psychologist go through the process of self-discernment and consider, first and foremost, his/her reasons for choosing the psychology profession, his/her commitments to the people that he/she serves, and his/her priorities in exercising his/her profession. The issue of whether psychologists should collaborate with the military in developing interrogation techniques that may be inhumane is beyond the jurisdiction of any law or code. This issue is a question of morality and integrity, which, in themselves, are very subjective areas of abstraction. In a moment of personal thought, psychologists should at least put themselves in the shoes of the victims of these inhumane interrogation – knowledge is indeed power, â€Å"and power corrupts† (Acton, 1887) Psychologists wield a considerable amount of knowledge with their training in the profession, and it is up to them whether they would use this knowledge to harm their fellow humans or not. (your family name) 6 The solution to this problem lies in the individual integrities of psychologists. Each psychologist should maintain an internal regulatory mechanism when participating in these operations. The secret is being able to say ‘no’ when what is being asked to be done is beyond our personal conviction, ideals, and the moral standards governing the profession. While laws and codes can only do so much in regulating what psychologists can do, these also serve as roads signs for psychologists so that they may be constantly reminded if they are already overstepping in their profession. On the issue of national security, some argue that the life of one can sometimes be dispensable for the life of all; this argument is a blind interpretation of the truth. Life, whether it be of only one, or of all is still life, and should not be meddled with in any aspect. Where does this put the psychologists conceding to collaborations with the military? In as much as we all want to believe in the integrity of our own chosen professions, we have to have faith in the individual and inherent goodness of man. We cannot condemn psychologists who work for the military just because we think what they are doing is inhumane, and it is also not up to us to pass personal judgment regarding the military’s motives; but in as much as we have hope and confidence in the rationality and discernment of human beings, we might as well advocate integrity and morality as a whole, not only in the field of psychology. Individual issues and motivations of psychologists cannot be questioned by a raging mob – but we can sure make them see the truth, and remind them of their commitment to the welfare of all, and not just for the satisfaction of brute and barbaric interests.

Behavioral Perspective of Psychology

When it comes to psychology or psychologists, most people imagine a person lying on a couch and talking to someone about their problems. Maybe even rats, and monkeys running around being studied by humans. However, psychology has changed dramatically since the beginning of its time. Constantly expanding on new approaches, from structural, functional, psychoanalytic, to the most modern seven major psychology perspectives, one of which I am going to touch on in the contrast of this paper. In the early 1900’s John B. Watson introduced the behavioral approach into the world of psychology. He is now known as the founder of behaviorism. Watson was influenced by the Russian physiologist Ivan Pavlov. Pavlov believed that, behavior results from within one’s environment. Well known behaviorist B. F. Skinner believed that we should use the behavioral approach to shape human behavior. Those who believed in the behavioral approach, viewed people and animals behavior and mental processes as being a direct impact or affect of their environment. They specifically believed, that we are a result of what we have learned from our environment. Behaviorism, mainly focuses on, how stimuli ( environment ) affects observable responses. Behaviorism is unique because, behaviorists believe in scientific methodology. They also believe that only observable behavior should be studied, being that it could be objectively measured. In the psychoanalytic approach, it is believed that in an unconscious state, there are thoughts, memories, and desires that people lack awareness of, yet these thoughts, memories, and desires have a great impact on one’s behavior. Sigmund Freud ( founder of the psychoanalytic perspective ) believed that events in our childhood can have a direct impact on our behavior as adults. When it comes to childhood, this could mean your neighborhood, ( environment ), family, peers, teachers, and so on. That’s why it is very important to watch what is said and done in the presence of young, and impressionable children. Thus in turn gives the two perspectives a common ground. In my opinion, I chose to elaborate on the behavioral perspective because, I, from my own personal experiences in my own life, and the observation of others and their life experiences, have found that, people tend to hold on to things that have happened to them in their past. Thus in turn, causes one to become very depressed, angry, afraid, and so on. I too, was once, one of those individuals, who held on to every trauma or shall I say bad experience that I have been faced with in my life. Through soul searching, and desperate desire of change in my life and way of thinking, began to de-root my issues from within. Noticing that holding on to my pain and fears was more traumatizing than just letting go. I then began facing my fears, and forgiving my pain. By doing so, I’ve noticed that I have become more of a happier person, able to communicate better, and more open minded to trusting again. I like this approach a little better than the others because to me, this approach is more of a realistic approach. I believe this approach is particularly of importance, because my belief is, the way to recovery is first admitting, addressing, and finding a solution to overcoming the obstacle, or obstacles holding you back. Critiquing this perspective, I would have to say that the strengths are, and I don’t mean to sound repetitive, however digging down to the root of a situation, and resolving the issues affiliated with the situation, is a great way to recover from the pain, memories, and various other obstacles that may be holding you back. In closing, though I am a huge fan of the behavioral approach, do not believe it would be a good idea for psychologists to focus only on the behavioral perspective. I believe there will be patients who do not, cannot, and will not want to talk about their underlying problems, fears, emotions, and so on. Another reason I do not think it would be a good idea for psychologists to focus only on the behavioral perspective is because all animals, human and no-human are unique in their own way. Not one animal, human or non-human, are exactly the same. The biopsychosocial model in psychology and medicine is essentially the idea that illness arises not just from a biological pathogen (as in the traditional biomedical model). However from a complex interaction of biological processes, such as genetics, brain functions, neurotransmitters, and evolution. Psychological factors, such as learning, thinking, emotion, personality, and motivation. And social forces, such as, family, culture, ethnicity, social class or social location, and politics. It suits many psychiatric illnesses particularly well. The interrelated influences interact with all of the seven major perspectives in modern day psychology. As far as conducting research, the biopsychosocial perspective may allow one to generate a more complex hypothesis and therefore have more complex findings at the end of the study. With that being said, there will be different problems, which need different approaches, to find different diagnosis, in order to give proper treatments. So again, though I deeply like the behavioral approach for my own personal reasons, believe that the biopsychosocial model approach, is the best approach to use in modern day psychology. My reasoning for this is because, the biopsychosocial approach, deals with more content. Thus for enabling better individual diagnosis’ and treatments for patients.

Financial statement analysis Essay Example | Topics and Well Written Essays - 500 words

Financial statement analysis - Essay Example The general rule is for a current ratio to be good it must be above 1.0. Both the current ratio and quick ratio of the company are excellent. The net margin of Happy Hospital is 6.49%. A net margin measures the profitability of a company. In order to determine whether a net margin is good or not one must consider the industry in which the company participates. A good database to find the industry ratios for different business industries is the Dun & Bradstreet database. If a company has a net margin that is higher than the industry standard this company is performing above the industry norm. Another element to consider is whether a company is a non-profit organization or for-profit company. The net margin in a non-profit organization is irrelevant since the strategy of the company is to break even. On the other hand for-profit organizations seek to maximize its profitability. The asset utilization of Happy Hospital was 63.56%. Firms seek to have high asset utilization because this me tric illustrates how much revenues are being generated with the assets of a firm. The financial leverage of Happy Hospital is 10.22%, while the financial leverage of St. Agnes is 86.40%. The financial leverage ratios show how much debt a company is using to finance its operation. The financial leverage position of Happy Hospital is much lower than St. Agnes Hospital.

Video Reaction paper 2 pages - Essay Example Then it gets quiet like as when things slowed down a little and planets began to cool. Our sun began to attract its planets and on one planet, after eons, life began. The second part makes me think of plants growing and spreading life all over the earth. Saturn was forming its rings and Venus gather in it clouds. Maybe Mars had a start at life also, but in the music, I can hear it wither away. Finally, as man came on the scene the angels sang and all the bells rang to mark the beginning of civilization. In this music, I hear heavy horns with loud base and many drums. The drums are the low sounding ones, such as kettledrums and big base drums. The strings are used to mark times that are more tranquil and the small, high-pitched instruments are used to create the sounds of life. The instruments used in this music seldom sound altogether. They seem to be painting a huge picture or maybe telling a story. Each group of instruments seems to have its own part and only a few times does the whole orchestra play together. I will listen to this again, because it is so complex that I know I cannot even hear it all at one sitting. The video was really very helpful. I learned about the way the music is created and why. The discussions about theory and different cultures that used different theory explain why some music to me does not sound good. This music comes close a few times to not sounding good, but then it moves back into what I like very soon. Seeing the orchestra play, this piece was really important for me as I could see the various instruments as they took up their parts. I did not even hear the oboes and I knew nothing about the special big horn used in this symphony. I thought the music was a little like a story or a conversation, so the video showing where this comes from was really interesting. I think if there were a lot of these about classical music then children would become interested in classical music

Sound Field Amplification Systems in the Classroom Research Paper

Sound Field Amplification Systems in the Classroom - Research Paper Example Sound field amplification is beneficial toward every child that is placed in a National Diffusion Network (NDN) equipped-classrooms. (www.classroomhearing.org, 2011) An estimated 33 babies are born daily with significant hearing loss in the U.S. This puts them significantly behind in auditory learning skills. Children who have this setback need all the help they can get when they get into the classroom setting. Teachers that are using this FM microphone system have reported that it improves the amount of attention each student has, and also that they better understand the directions when they are given. This system also lowers the number of times the teachers need to repeat themselves which give them more time to move on and learn more material. Along with these benefits there are fewer discipline problems and students that have a better attitude toward learning. There are many distractions and interfering noise that come with teaching in a child’s classroom. This system helps to make them less noticeable. Students who had NDN equipped classrooms had better read and language scores after just one years. Fewer employees are needed to achieve the same or even a superior education, making the system more cost effectively. The classrooms that have NDN radios help make the children with disabilities seem more â€Å"like† everyone else, while they are achieving academic success at the same rate. These classroom amplification systems should not only be used in classrooms where there are hearing-impaired children present. Many children have perceptual difficulties while listening, without actually having any hearing loss. This would mean that a child hears perfectly well, but has difficulty grasping and interpreting the message that is being given. These types of children are present in every normal sized classroom. Sound field amplification cannot only help them to interpret the lessons better, but also help them realize that they do have what it takes t o be at the same level as their peers. This also helps with self confidence levels of children, making them all feels like they are equal in the class. Since most teachers are not taught how to tell whether or not a child is suffering from an auditory problem, they can sometimes mistake the children for having a disciplinary problem. Having these systems in every adolescent classroom would help to diminish the amount of disciplinary action that is taken upon children that have an underlying disability. Problem Statement Teachers and school often have a hard time projecting their voice so that all students can hear what is said at the front of the classroom, even in the back of the classroom. List of Definitions Sound Amplification System: a sound amplification system is a set of speakers inside the walls, or ceiling of a classroom and the teacher was a microphone around the teacher’s neck so that all students can hear even those in the back of the classroom. ANSI: American Na tional Standard Institute Microphone: a microphone is a device worn around the teacher’s neck that is connected with the speakers and the classroom, and works together

Optional Technologies Adopted in the Construction of Building Elements Essay

Optional Technologies Adopted in the Construction of Building Elements - Essay Example Design professionals significant role in the quality of the built environment cannot be denied. Buildings in the contemporary world are a complex undertaking that require many different skills and materials. In this regard, the capabilities of the engineers and architects on the integrated design team are critical for the overall success of the design. In order to carry out the design and propose various alternatives, some background data is often required. This is usually with reference to the location of the proposed project and its various jurisdictions. The design process is then guided onwards by the knowledge of such project information. It is based on this that the relevant safety factors can be applied in the design so that the proposed methods and constructional technologies are safe and appropriate (EMMITT, BARRY & GORSE, 2010, p. 14). With the layout plan given for a proposed four-storey commercial building, with its components and the boundary conditions, different optional building technologies can be used to come up with the most appropriate designs. The building elements considered are as follows: Basements in commercial buildings are in most cases constructed to serve as foundations for the superstructure of the building, and in others to increase its utility to provide space that can be used by occupants of the building (FLEMING, 2005, p. 33). When adequately and properly constructed, they can be used for the following purposes: The intended use of the basement must be determined first before any design decisions are made. This will also have an impact on the quality of the basement. The level of performance of the basement areas is to be determined from the onset of construction to help in cost estimations and the material choice for the basement and its surrounding features.

Developing probes of cathepsin L Lab Report Example | Topics and Well Written Essays - 1500 words

Developing probes of cathepsin L - Lab Report Example The resin has a linker of acid sensitivity that allows the protection of dipeptide. Besides, the cleavage process also affects the selection of the resin. The synthesis process involved adopting the SPPS protocol which involves the use of DMF, resin, reagents like 4-Dimethylamionpyridine (DMAP) and DMF before the addition of liquid reagent (DIC). The resins were washed with DCM3, IPO 3 and NMP 3 several times. The cleavage process involves using a dilute TFA process. The dry resin was placed in the glass funnel and 1% 10 ml FTA of the dry DCM added, filtered through the application of nitrogen pressure on the flask with ten percent pyridine (2ml) dissolved in methanol. The washing of resin and checking of the filtrate using either the HPLC or the TLC method helped in the process. The mass spectrometry was used for the identification of the protein profiles. The mass of the protein were evaluated by the calculation of m/z peaks. The cleavage of the protein was successful and lead to t he identification of 12 peaks. Majority of the cathepsins are cysteine protease while others are either serine or aspartic proteases. The secretion of cathepsins in the body can be induced by factors like interferon and tumour necrosis factor (Hassanein et al., 2009). Different cathepsins are induced by different molecules, for instance cathepsin L is induced by nicotine. Cathepsins are proteases. Proteases are enzymes with the potential to degrading the proteins. These enzymes are ubiquitous in animals and other organisms. The cathepsins occur in different forms and families. Their differences are based on the differences in structural domains (Puzer et al., 2005). Other factors affecting the type of cathepsins include the proteins they cleave and the catalytic mechanisms. The optimal environment for these enzymes is acidic media, therefore, most of the cathepsins undergo activation at lower ionic concentration characterised by the

After the initial explosions the blowout preventer’s emergency functions failed to seal the well, allowing the leak to occur†. (BP oil, 2011) The language of this statement stresses that the occurrence was an â€Å"accident† which implies that it is out of the control of the company, and something that happened by chance. The expression of regret is a recognition of the pain and suffering that has been suffered by those who died and others who know them. The words do not imply that BP caused these deaths, or that they accept responsibility for them. The words just regret that something has happened. Because of the location of the incident near the American coastline there was immediate press interest and a flood of images and commentaries on the incident itself and the on-going and severe pollution of the area around the rig. BP was forced to treat this as a major public relations disaster as well as an environmental one and health and safety one. It was the attention of the press over a long period of time that turned this from one incident into a long series of further damaging developments. Not only the leak was highlighted, but also the inability of the company to stop it, and the inadequate clean up and recovery attempts. â€Å"We have acted to take responsibility for the clean-up, to respond swiftly to compensate people affected by the impact of the accident, and to look after the health, safety and welfare of the large number of residents and people who helped respond to the spill.

BP Domestic and Global - Essay Example BP needs to be strategic. A scenario where by there is a plan of action that channels an organization’s resources so that it can effectively differentiate itself from competitors and accomplish unique and viable goals. Strategies are organized based on the organization’s strength and weakness relative to the competition and assessing opportunities. This can be done by reducing risk. Though no business can prosper without taking risks, it is necessary to take a calculated risk so that the risk itself is managed. The company social investment can be too increased.There should a tangible demonstration of companies’ corporate citizenship philosophy. For example, Indonesian government and BP have embarked on a major initiative to develop one of the major gas fields on a partnership basis. Extracted gas is converted into liquefied natural gas (LNG) for export to global market. The firm is located in mangrove ecosystem of about 300000 hectares of land which support appr oximately 300000 households and can create conflict. To avoid this conflict, 70% of post tax revenue from the project is returned to the community improving infrastructure and government services aimed at providing lasting socio-economic benefit. Indonesia government, BP, and UNDP formulated Diversified Growth Strategy (DGS) for the community and affected project area. They have also placed special emphasis on linking Millennium Development Goal MDG1 poverty reduction and MDG7 protection of the environment (Tims, 2007).

Carl Jung Theory Essay Jungs theory divides the psyche into three parts. The first is the ego, which Jung identifies with the conscious mind. Closely related is the personal unconscious, which includes anything that is not presently conscious, but can be. The personal unconscious is like most peoples understanding of the unconscious in that it includes both memories that are easily brought to mind and those that have been suppressed for some reason. But it does not include the instincts that Freud would have it include. But then Jung adds the part of the psyche that makes his theory stand out from all others: the collective unconscious. You could call it your psychic inheritance. It is the reservoir of our experiences as a species, a kind of knowledge we are all born with. And yet we can never be directly conscious of it. It influences all of our experiences and behaviors, most especially the emotional ones, but we only know about it indirectly, by looking at those influences. There are some experiences that show the effects of the collective unconscious more clearly than others: The experiences of love at first sight, of deja vu (the feeling that youve been here before), and the immediate recognition of certain symbols and the meanings of certain myths, could all be understood as the sudden conjunction of our outer reality and the inner reality of the collective unconscious. Grander examples are the creative experiences shared by artists and musicians all over the world and in all times, or the spiritual experiences of mystics of all religions, or the parallels in dreams, fantasies, mythologies, fairy tales, and literature. A nice example that has been greatly discussed recently is the near-death experience. It seems that many people, of many different cultural backgrounds, find that they have very similar recollections when they are brought back from a close encounter with death. They speak of leaving their bodies, seeing their bodies and the events surrounding them clearly, of being pulled through a long tunnel towards a bright light, of seeing deceased relatives or religious figures waiting for them, and of their disappointment at having to leave this happy scene to return to their bodies. Perhaps we are all built to experience death in this fashion. Archetypes The contents of the collective unconscious are called archetypes. Jung also called them dominants, imagos, mythological or primordial images, and a few other names, but archetypes seem to have won out over these. An archetype is an unlearned tendency to experience things in a certain way. The archetype has no form of its own, but it acts as an organizing principle on the things we see or do. It works the way that instincts work in Freuds theory: At first, the baby just wants something to eat, without knowing what it wants. It has a rather indefinite yearning, which, nevertheless, can be satisfied by some things and not by others. Later, with experience, the child begins to yearn for something more specific when it is hungry a bottle, a cookie, a broiled lobster, a slice of New York style pizza. The archetype is like a black hole in space: You only know its there by how it draws matter and light to itself. The mother archetype The mother archetype is a particularly good example. All of our ancestors had mothers. We have evolved in an environment that included a mother or mother-substitute. We would never have survived without our connection with a nurturing-one during our times as helpless infants. It stands to reason that we are built in a way that reflects that evolutionary environment: We come into this world ready to want mother, to seek her, to recognize her, to deal with her. So the mother archetype is our built-in ability to recognize a certain relationship, that of mothering. Jung says that this is rather abstract, and we are likely to project the archetype out into the world and onto a particular person, usually our own mothers. Even when an archetype doesnt have a particular real person available, we tend to personify the archetype, that is, turn it into a mythological story-book character. This character symbolizes the archetype. The mother archetype is symbolized by the primordial mother or earth mother of mythology, by Eve and Mary in western traditions, and by less personal symbols such as the church, the nation, a forest, or the ocean. According to Jung, someone whose own mother failed to satisfy the demands of the archetype may well be one that spends his or her life seeking comfort in the church, or in identification with the motherland, or in meditating upon the figure of Mary, or in a life at sea. Mana You must understand that these archetypes are not really biological things, like Freuds instincts. They are more spiritual demands. For example, if you dreamt about long things, Freud might suggest these things represent the phallus and ultimately sex. But Jung might have a very different interpretation. Even dreaming quite specifically about a penis might not have much to do with some unfulfilled need for sex. It is curious that in primitive societies, phallic symbols do not usually refer to sex at all. They usually symbolize mana, or spiritual power. These symbols would be displayed on occasions when the spirits are being called upon to increase the yield of corn, or fish, or to heal someone. The connection between the penis and strength, between semen and seed, between fertilization and fertility are understood by most cultures. The shadow Sex and the life instincts in general are, of course, represented somewhere in Jungs system. They are a part of an archetype called the shadow. It derives from our prehuman, animal past, when our concerns were limited to survival and reproduction, and when we werent self-conscious. It is the dark side of the ego, and the evil that we are capable of is often stored there. Actually, the shadow is amoral neither good nor bad, just like animals. An animal is capable of tender care for its young and vicious killing for food, but it doesnt choose to do either. It just does what it does. It is innocent. But from our human perspective, the animal world looks rather brutal, inhuman, so the shadow becomes something of a garbage can for the parts of ourselves that we cant quite admit to. Symbols of the shadow include the snake (as in the garden of Eden), the dragon, monsters, and demons. It often guards the entrance to a cave or a pool of water, which is the collective unconscious. Next time you dream about wrestling with the devil, it may only be yourself you are wrestling with! The persona The persona represents your public image. The word is, obviously, related to the word person and personality, and comes from a Latin word for mask. So the persona is the mask you put on before you show yourself to the outside world. Although it begins as an archetype, by the time we are finished realizing it, it is the part of us most distant from the collective unconscious. At its best, it is just the good impression we all wish to present as we fill the roles society requires of us. But, of course, it can also be the false impression we use to manipulate peoples opinions and behaviors. And, at its worst, it can be mistaken, even by ourselves, for our true nature: Sometimes we believe we really are what we pretend to be! Anima and animus A part of our persona is the role of male or female we must play. For most people that role is determined by their physical gender. But Jung, like Freud and Adler and others, felt that we are all really bisexual in nature. When we begin our lives as fetuses, we have undifferentiated sex organs that only gradually, under the influence of hormones, become male or female. Likewise, when we begin our social lives as infants, we are neither male nor female in the social sense. Almost immediately as soon as those pink or blue booties go on we come under the influence of society, which gradually molds us into men and women. In all societies, the expectations placed on men and women differ, usually based on our different roles in reproduction, but often involving many details that are purely traditional. In our society today, we still have many remnants of these traditional expectations. Women are still expected to be more nurturant and less aggressive; men are still expected to be strong and to ignore the emotional side of life. But Jung felt these expectations meant that we had developed only half of our potential. The anima is the female aspect present in the collective unconscious of men, and the animus is the male aspect present in the collective unconscious of women. Together, they are referred to as syzygy. The anima may be personified as a young girl, very spontaneous and intuitive, or as a witch, or as the earth mother. It is likely to be associated with deep emotionality and the force of life itself. The animus may be personified as a wise old man, a sorcerer, or often a number of males, and tends to be logical, often rationalistic, and even argumentative. The anima or animus is the archetype through which you communicate with the collective unconscious generally, and it is important to get into touch with it. It is also the archetype that is responsible for much of our love life: We are, as an ancient Greek myth suggests, always looking for our other  half, the half that the Gods took from us, in members of the opposite sex. When we fall in love at first sight, then we have found someone that fills our anima or animus archetype particularly well! Other archetypes Jung said that there is no fixed number of archetypes that we could simply list and memorize. They overlap and easily melt into each other as needed, and their logic is not the usual kind. But here are some he mentions: Besides mother, their are other family archetypes. Obviously, there is father, who is often symbolized by a guide or an authority figure. There is also the archetype family, which represents the idea of blood relationship and ties that run deeper than those based on conscious reasons. There is also the child, represented in mythology and art by children, infants most especially, as well as other small creatures. The Christ child celebrated at Christmas is a manifestation of the child archetype, and represents the future, becoming, rebirth, and salvation. Curiously, Christmas falls during the winter solstice, which in northern primitive cultures also represents the future and rebirth. People used to light bonfires and perform ceremonies to encourage the suns return to them. The child archetype often blends with other archetypes to form the child-god, or the child-hero. Many archetypes are story characters. The hero is one of the main ones. He is the mana personality and the defeater of evil dragons. Basically, he represents the ego we do tend to identify with the hero of the story and is often engaged in fighting the shadow, in the form of dragons and other monsters. The hero is, however, often dumb as a post. He is, after all, ignorant of the ways of the collective unconscious. Luke Skywalker, in the Star Wars films, is the perfect example of a hero. The hero is often out to rescue the maiden. She represents purity, innocence, and, in all likelihood, naivete. In the beginning of the Star Wars story, Princess Leia is the maiden. But, as the story progresses, she becomes the anima, discovering the powers of the force the collective unconscious and becoming an equal partner with Luke, who turns out to be her brother. The wise old man guides the hero. He is a form of the animus, and reveals to the hero the nature of the collective unconscious. In Star Wars, he is played by Obi Wan Kenobi and, later, Yoda. Notice that they teach Luke about the force and, as Luke matures, they die and become a part of him. You might be curious as to the archetype represented by Darth Vader, the dark father. He is the shadow and the master of the dark side of the force. He also turns out to be Luke and Leias father. When he dies, he becomes one of the wise old men. There is also an animal archetype, representing humanitys relationships with the animal world. The heros faithful horse would be an example. Snakes are often symbolic of the animal archetype, and are thought to be particularly wise. Animals, after all, are more in touch with their natures than we are. Perhaps loyal little robots and reliable old spaceships the Falcon are also symbols of animal. And there is the trickster, often represented by a clown or a magician. The tricksters role is to hamper the heros progress and to generally make trouble. In Norse mythology, many of the gods adventures originate in some trick or another played on their majesties by the half-god Loki. There are other archetypes that are a little more difficult to talk about. One is the original man, represented in western religion by Adam. Another is the God archetype, representing our need to comprehend the universe, to give a meaning to all that happens, to see it all as having some purpose and direction. The hermaphrodite, both male and female, represents the union of opposites, an important idea in Jungs theory. In some religious art, Jesus is presented as a rather feminine man. Likewise, in China, the character Kuan Yin began as a male saint (the bodhisattva Avalokiteshwara), but was portrayed in such a feminine manner that he is more often thought of as the female goddess of compassion! The most important archetype of all is the self. The self is the ultimate unity of the personality and is symbolized by the circle, the cross, and the mandala figures that Jung was fond of painting. A mandala is a drawing that is used in meditation because it tends to draw your focus back to the center, and it can be as simple as a geometric figure or as complicated as a stained glass window. The personifications that best represent self are Christ and Buddha, two people who many believe achieved perfection. But Jung felt that perfection of the personality is only truly achieved in death.

Characterization of Tom in The Great Gatsby Essay Example for Free

Characterization of Tom in The Great Gatsby Essay In the first three chapters of The Great Gatsby by F.Scott Fitzgerald, he characterized Tom Buchanan as violently aggressive in order to show the kind of man that had turned out from the Ivy League school and have contributed to two different social classes. For example, in the first chapter of the book, Nick introduces us couple of characters as well as Tom Buchanan and he says the following â€Å"Now he was a sturdy straw-haired man of thirty with a rather hard mouth and a supercilious manner. Two shining arrogant eyes had established dominance over his face and gave him the appearance of always leaning aggressively forward† (pg.7). We are told that Tom has a hard mouth and arrogant eyes. He is said to be always leaning forward aggressively, making up for the unmanly clothes hes wearing at the time and very muscular with a cruel body. Nick describes Tom looking aggressive just by his looks without any further detail of how he acted aggressively. As a graduate from a prestigious school, Tom would be expected to be more characterized as a good, pleasant character when describing an educated man, however Tom was the opposite and Fitzgerald does this to show that the characteristic of a man does not depend on the school they had attended and graduated from. Furthermore, in chapter 2 it is proven that Tom is violent â€Å"Sometime toward midnight Tom Buchanan and Mrs. Wilson stood face to face, discussing in impassioned voices weather Mrs. Wilson had any right to mention Daisy’s name†¦I’ll say it whenever I want to! Daisy! Dai- Making a short deft movement, Tom Buchanan broke her nose with his open hand† (pg.37). At their little gathering party, Tom there breaks his lover, Myrtles, nose just because Myrtle had not stopped chanting Daisy’s name even if she had been warned by Tom before. Tom expresses his aggressiveness when he becomes violent when Myrtle does not stop. Fitzgerald is showing that not all man graduating from Ivy League school such as (Yale, Oxford, and Princeton) are all well-mannered, with a good characteristic as one would think.

Pestel Analysis On Petroleum Industry Economics Essay

Pestel Analysis On Petroleum Industry Economics Essay ABSTRACT: In the history of the mankind, the need of resources was the most important factor for political, technological, economic, social evolutions. In modern times need of energy resources become more significant than other industries who were more important during the past like the production of wood, stone, horse breeding, productions of ships, weapons, constructions of buildings and even gold production. The primary energy source is represented by petroleum, commonly known as oil. Petroleum is most used in transport, energy, petrochemical, agriculture and other industries that need oil products in the production of goods. Example: Metallurgy. In this paper it will be present the need of a macro-environmental analysis at the petroleum industry and the external factors that have a powerful influence on this industry. KEYWORD: environment, factors, oil, resource, PESTEL analysis, influence JEL CLASSIFICATIO: L71, L72, N01, N10, N30 1. INTRODUCTION In pre-industrial revolution time, oil was used for making and maintaining the fire, in the blacksmith, in constructions and in the period of war as a weapon (fire traps, fire projectiles of bows or siege engines and even a component of the substance used for medieval flamethrower named Greek fire, which was used in naval warfare). With the development of electricity and transport, the need for the oil rise very much and surpasses the need for coal or natural gas, which were used for the same purpose. Petroleum (oil) industry represents one of the most important components of the energy industry who is like the circulatory system of the human body to the modern economy. Oil industry is divided in: upstream (exploration, development, extraction of oil and natural gas), downstream (transport by oil tanks or pipelines, refineries, retailers and consumers). PESTEL analysis represents of the most important method used to analysis external environment within an organization or an industry sector (Moldoveanu, 2007). Necessity of using the PESTEL analysis on the petroleum industry is represented by the important role that this industry has on the economic, political and social systems around the world. 2. IMPORTANT In this paper, I want to show the importance of the external factors of macro-environment on petroleum industry and complementary industries. I would use PESTEL analysis because it responds to the questions: Are only political, economic and social factors that influence the petroleum industry? The oil industry by could be influenced by the modification of a factor that has no direct contact with industry? 3. PESTEL Analysis on Petroleum Industry PESTEL analysis is used by organizations for identifying the factors of external environment of the market that could influence the organization and entire industry. PESTEL analysis is formed by six macro-environment group of factors: political factors, economic, social, technological factors, environmental factors and legal factors. Other authors add new group factors, named international (Moldoveanu, 2007), but I dont want to split to add this factors because all PESTEL groups of factors contain both national and international description. Macro-environmental factors are less influenced by companies than micro-environmental factors (customers, employee, suppliers, shareholders, media and competitors), but companies of oil industry can have bigger influence of macro-environment than companies from other industries. This fact is resulted because of the need for energy resources for political, economic, social, technological, environmental and legal activities. 3.1. Political factors Political factors are represented by the influence of a political entity (party, country, organizations or other type of faction) on the national level, regional level or international level. Most of the countries consider that the oil industry (upstream and downstream) is a strategic point in political, economic and social needs of a country, because this industry has a great influence on transport capacity, energy production, industrial production, chemical production, agriculture and social welfare. The energy independence is a priority objective of every country who wants to be free from a political blackmail from other countries or international organization. The most influent organization in oil production is OPEC (Organization of the Petroleum Exporting Countries) who has more than 42, 8% of world oil production, other considerable producers of oil or of another substituent, products are United States of America, Countries of European Union, Russia, China, Canada and Brazil. T he consumers who have a great influence on the oil markets are United States of America, China and western European Union countries. For mutual gain, some countries make trade agreement for exchanging of energy resources for money, technology other resources or even protection. A powerful influence over the production of oil and the price is made by instable situation from the Middle East, where every conflict could disturb oil production and transport, resulting in the rising of oil price. Another region that has a great influence upon the petroleum market is ex-soviet space, where disputes are likely resolved by energetic and political blackmail. The policy of foreign oil independence of the United States diminished energetic resource imports, because of that in Alaska were build new exploitations of oil or natural gas and development of substitutes. The austerity programs of European Union have reduced the need for fuels, because of declining of the economic activities and the so cial welfare. The economic crisis made the need for cheap fuels became a priority for the major players of the global stage. Because of this situation, many territorial disputes reappear between countries for oil and natural-gas reserves like: the Falkland Islands dispute between United Kingdom and Argentina; the Arctic plateau dispute between United States of America, Canada, Iceland, Norway and Russia; the Senkaku islands dispute between China, Taiwan and Japan; the South China Sea dispute between numerous Asian countries. National politic factors are represented by grade of authority of the state, political parties, non-governmental organizations and in some cases different factions (rebels, paramilitary entities). Grade of authority of the state represent the power that have the government upon the society, economy, technology, laws. The authority of the state is higher in authoritarian states like dictatorships, theocracies, non-constitutional monarchies, tribal society and is lower in democratic republics and constitutional monarchies were the political power is given by people of the country to the elected politicians. Political parties influence the petroleum industries by imposing state strategy for electoral or economic gains. The non-governmental organizations influence the oil market by promoting anti-pollution campaigns or liberalization of the fuel market. Paramilitary factions use influence on oil industry for blackmailing or for imposing some fees in territories that are controlled by the m, cutting the transport of oil for political gains. Oil companies can have influence on political factors in regions or countries were oil in primary source of making income and in regions or countries were the energy resource are scarce and attracting additional one is need for good function of economic activities. In modern economic, because of the globalization, the state canà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢t protect the external market like in mercantile system(Strange S., 1996), resulting that companies can occupy new markets or acquire new resources alone. 3.2. Economic factors Economic factors are represented by the: influences of the supply and demand on the oil price; influences of the supply or demand of the complementary goods; influence of the supply and demand of substitute resources; the USD exchange rate (petrol-dollar policy); the price of the oil barrel on the important stock exchanges; economic situation on regional and global stages; value of the known reserves, interest rate for financing; value of stock market indexes (DOW Jones, StandardPoor). The demand for fuels is influenced by variation of transport activities (road, rail, aviation, naval) that represent almost 60 %(OPEC,2011), petrochemical industry, other industries, agriculture and energy production. Variation of need for road transport activities is influenced by the number of the auto vehicles used by population or organizations; the earns of every car owner, the frequency of using his own car, the customer culture for fuels effect on the environment, the road infrastructure, seasons, touring activities. Rail transport is represented by trains that use fuels for transport; this kind of transport is used in developing countries that have big oil production. Aviation is one of the transport sectors that grown very rapidly, representing 6% of total oil demand (OPEC,2011), two thirds been represented by OECD (Organization For Economic Co-Operation And Development). Oil demand for naval transport is represented in big proportion by cargo ships that transport goods from developing countries (goods and resources producers) to developed countries (services producers). Petrochemical industry represents approximately 10% of total oil demand and the products that are produced by this industry are: plastics, synthetic fibers, synthetic rubber, detergents, paints, adhesives, aerosols, insecticides, pharmaceuticals and others. Others industry sectors which demand oil or complementary products from oil are iron and steel industry, cement industry, auto vehicles industry, naval industry, mining, construction and many others. In agriculture demand for oil and complementary products are for a wide range of activities like farming, pasturing, animal husbandry, fishing, hunting, beekeeping and many others. Table 1.

This fact is explained by the beginning of financial crisis that influenced negatively the income of the companies and of the population, making the companies and people to cut the cost, or to become insolvent, resulting to diminish of economic activities across the world who make the demand for transport to fall that making the fall of oil price. 3.3. Social factors Social factors are represented by demography, culture, ethnic structure, religion structure, inter-cultural relation, structure of family, ideological view, literacy, urbanization, income distribution, migration, use of communication technology, cultural view to the different products. All around the world, do not exist a culture that is against oil exploitation and for using the oil products, most of the population saw the oil industry like a necessity for development and welfare, but are segments within the population who see the oil industry as an important factor of pollution of the environment. Population which has culture of the protection of the natural environment is located in developed countries, because not need a high rate of developing. In the countries were populations are more friendly with environment; government imposes pollution fees and pollution reduction laws and norms to petroleum industry, and complementary industries. Many companies which make complementary products, like cars, invest in reduction of fuel consumptions or start to produce hybrid products. In the developing countries, populations from see the need for development and growing rate of welfare more important than environment protection; they accept the pollution like a cost for e conomic growth.

The populations of developed countries that consume most of the fuels and energy, in these days, are growing slow and are ageing very rapidly, resulting in diminish of the need for oil in future. However, the growth of the population, in developing countries, will impose the rise of the energy resources for growing transport, petrochemical industries and electricity production needs. So de results will be that the need from developing countries for oil will surpass the reducing of need from developed countries, so the demand for oil will grow. Urbanization is another factor that influences the need for energy, because urban population consumes more energy resources for transportation, electric energy or petrochemicals (plastics, fibers) than rural population. Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat forecast that in 2035 the urban population will grow with 50,69% and rural will decrease with 4,17%. In developing countries growing of urban population will be larger than developed countries with almost 1432 millions. Rural population in developed countries will decrease with almost 16 milions and in developing countries will remain almost the same. Table 4.

Technological factors Technological factors are represented by technologies, techniques and methods that influence the activities within an organization (Palmer A. Hartley B., 2009). The technological factors could influence an organization from inside the industry, by making the need to acquire the last technologies (by buying equipment), techniques and methods (by hiring a trained human resource in new techniques or train the old human resource with the new techniques and methods). Once acquired, these factors will influence the organization from inside. In oil industry, the technologies are used exploration, in exploitation, transport( roads, oil tanks, pipelines), in refineries, in storage, in promoting marketing strategies, in selling; in researching and development of the brand-new products or in upgrading the old ones, in reducing the time of production the losses from the production process. Secondary technologies and techniques could be used in environment protection, workers protection, in impr oving the efficiency of the management by using of new software and hardware, improving the maintaining and repairing activities. All these factors could be used against an oil company, if a rival company owns them like a competitive advantage. Because of that will result in a perpetual race (Nicolescu Verboncu, 2009) for acquiring the news and the most efficient technologies, techniques and methods that will have the results of takings a greater share from downstream market and a greater share from the upstream market, to acquire more oil reserves or to impose the price. Technologies that influence the oil company from outside the oil industry can influence entire oil industry (upstream and downstream). These technologies are represented by the complementary products and substitutable products. The complementary products influence the demand for oil by developing technologies that will reduce the consumption of oil products or replaced them with other a substitutable product. The complementary products are represented by auto vehicles, airplanes, ships, petrochemicals (plastics, synthetic fibers, synthetic rubber, detergents, paints, adhesives, aerosols, insecticides and pharmaceuticals), energy, agricultural product or other industrial products. The substitutable products are represented by-products of the rest of energy industries. These industries are: the coal industry, natural-gas industry (which includes the new shale gas industry), nuclear industry, biomass industry, hydro industry and other renewable-energy industry (solar, wind, geothermal). Like the many coal and gas industries, the oil industry in life phase of maturity, because development of the new technologies became very hard and oil reserves are half depleted. Table 5.

Nuclear will almost double the production, but more use of atomic energy will be limited because of fear of nuclear disasters like Chernobyl and Fukushima. Biomass will grow with almost 240%, but the principal problem of this resource is that will compete with the need for food production, because plants, which made biomass, are using the same soil that is used in agriculture for cultivating the wheat and corn or pastures of domestic animals. Hydro will almost double in 25 years, but the great difficulty will be to find new efficient places for building hydro centrals, because most of the rivers will also have hydro central. Rest of renewable-energy production will grow will approximately seven times, from 2008 to 2035; the main issues of renewable energy are: investments are high in comparison with fossil fuels, efficiently is lower, in most of the world region renewable energy can be produced only in some seasons, and it has a dependence to weather conditions. 3.5. Environment factors Environment factors are represented by the geographical position, landform, climate, fauna, flora, rock structure and natural resource that are in case of petroleum companies represented by oil reserves. Geographic position influence the activity of oil companies because it defines the distances between exploitation, refiners and consumers (for example, oil from Middle East can be transported half the world, exploitation to refiners), or could influence the demand for oil because of transports, international trade and migration. Landform influences the difficulty of exploitation, transportation to the refiners and consumers; demand is influenced by the consumption of the fuel in heavy terrains. Climate influences the difficulty of oil exploitation in time of the cold season in north climates, or hot seasons of desert climate, demand for oil grown in winter because of low speed traffic or energy consumption. Flora and fauna influence cost oil exploitation because of existing of the oi l reserves in natural parks, or because of existing difficult access area because of vegetation and dangerous animals. Rocks structure made difficulties of exploration and exploitation oil. World oil reserves are estimated to 1481.526 billion barrels according to OPEC Annual Statistic Bulletin 2012. The biggest oil reserves are in Saudi Arabia, Canada, Iran, Kuwait, Arab Emirates, Venezuela Russia, Libya, Nigeria, United States of America, China, Qatar, Mexico, Algeria and India. These countries have own 95% of oil reserves. One specification of the environmental factors is represented by natural disasters: hurricanes, tornados, cyclones, snow storms, sand storms, extreme temperatures, earthquakes, tsunamis, volcanic eruption that could make material loss and casualties, but could disturb economic activities. Economic activities that could be disturbed are road, rail, naval, air traffic, could decline the demand for unnecessary goods and raise the demand for the primary need goods l ike water, food, pharmaceutics, construction materials, fuels, clothes. Petroleum industry influences the natural environment because of pollution and capacity of changing from natural to artificial environment by fueling the developing of modern economy. Pollution is represented by fuel emission from uses of auto vehicles, airplanes, ships and emissions from refineries that produce fuels or other petrochemical products that have a great influence on climate changing. Other pollution events are represented by accidents that can happen in activities of exploration, exploitation, refining and transport, contaminating the water, air and soil with oil, fuels or wastes. 3.6. Legal factors Legal factors are represented by constitutions, laws, norms and regulations of the local authorities, governments, international institutions, international communities (European Union, the North American Free Trade Agreement, the African Union and the Association of South East Asian Nations). This factors influence the modalities of exploration, of exploitation, of the refiner, of transportation and of commercialization of oil and oil products. The legal factors also impose laws and regulations for pollution, social protection, work protection, work regulation, competition regulation, anti-trust regulation, consumer protection, international trade (trade agreements between nations or embargoes to some countries), subsidies, the taxes( like the excise rates for fuels and oil price or taxes and fees over profit to the energy companies). Table 6. Tax rate in comparison with price Country Oil price USD per liter Tax rate Tax United Kingdom 1.76 65.1% 1.15 Germany 1.53 66.3% 1.02 Italy 1.418 66.3% 0.94 France 1.49 63.7% 0.95 Japan 1.14 49.6% 0.57 Canada 0.90 33.3% 0.30 USA 0.75 16.0% 0.12 Source: Who get What from imported oil (2011) http://www.opec.org/opec_web/en/publications/341.htm 4. CONCLUSION In conclusion, the importance of knowing the macro-environment on an industry such as important like petroleum industry is crucial in the modern economy, because these factors represent the opportunities and threats of this economic sector. Many specialists think that the change from fossil fuels to the renewable resources would resolve many of the problems and threats that the oil industry has. So the transition from oil to renewable resources should be faster, omitting many variables upstream and downstream of this industry. If a change of the principal energy resources will be made, it will be required to take caution steps, because this could make a shortage of the energy resources that could destabilize the entire world social-economic-system. For changing main energy resource will be necessary to reconvert many equipments and machinery, training the human resource, make social campaign to encourage the people to use new fuel, invest in new research about efficiency of the new f uel, the environment impact, search for new reserves and make new regulation for the use of this resource.

Compare and Contrast 7 of the Main Ethical Principles Essay -- Ethics

Despite the implementation of a certain code of conduct and belief system into most individual's everyday lives, the concept of ethics or moral philosophy remains a hazy area, left to be tackled by philosophers and exceptional theorists. The assessment of major ethical systems over the course of the semester has forced me to reevaluate the fundamentals of my own moral philosophy and reconsider the role of ethics as a more average field of thought than I had once considered. Included in the major ethical systems examined throughout the course were: Cultural Relativism, Religious Ethics, Ethical Egoism, Utilitarianism, Kant's Moral Absolutism, Social Contract, and Ethics of Virtue. The explication of these very different systems and their pillars can be a sound basis for analyzing one's personal moral philosophy. In the 4th century BC the Greek sophist Protagoras, living in the midst of a period of Greek historical turmoil, turned to philosophy and an experimental model that he would develop to attempt to find any universally accepted moral principals. After collecting data from cultures he had the ability to examine, he concluded that he didn't find any universally accepted moral principals, which led him to the conclusion that there are no moral absolutes. In this case, when discussing something that has universal acceptance, it means with absolutely no exceptions, and a moral absolute is something that exists in the real world, independent of changes in perception. Protagoras concluded, through the use of human opinion for his data, likely to be not the most reliable source, that if morals are not absolute in nature, they are relative to the cultures that they are inherent to. This conclusion leads him to be called the father... ...ood mixture, consisting of a pinch of Cultural Relativism, a dash of Religious Ethics, a little bit of the others, and a lot of the Ethics of Virtue, would be the most beneficial to my life. It may seem like this conclusion is a cop out, a way to not choose a side in the battle of moral philosophies, but really, the reality of the world lends itself to a mixture, from cultural diversity to the diversity necessary for a healthy diet, a composition of many ideas seems to prevail, hardly ever just one.

The Creation of Encyclopedia :: History Philosophy Philosophers essays

The Creation of Encyclopedia Webster's New World Dictionary defines the Enlightenment as "an 18th-century European philosophical movement characterized by rationalism, an impetus toward learning, and a spirit of skepticism and empiricism in social and political thought." During this period of enlightenment, the way the world was viewed changed in a large part because of the group of philosophers known as the philosophes. During the Enlightenment the greatest philosophical movement of the philosophes was the creation of the Encylopedie ou Dicionnaire raisonne des sciences des arts et des mà ©tiers, or in English; the rational dictionary of the sciences, the arts and the crafts, otherwise known as the Encyclopedia. The philosophe's encyclopedia is regarded so highly because it brought about a new way of thinking, an enlightened way of thinking. The encyclopedia, according to the Electric Library, dates back to Aristotle and his attempts at compiling large amounts of information. Other encyclopedia's were written after Aristotle's attempt, including one that was published just a few years before the philosophe's Encyclopedia, the Ephraim Chambers's Cyclopaedia. (1) According to the Denis Diderot History web page, the Ephraim Chambers's Cyclopaedia was the inspiration for the philosophe's Encyclopedia. The intention was to create a French translation of the Ephraim Chambers's Cyclopaedia, but when Denis Diderot was hired as editor, the outlook of the Encyclopedia changed. Diderot did not want a mere translation; instead he wanted an encyclopedia that would "enlighten and explain every aspect of existence." (1) Denis Diderot and another editor, Jean le Rond d'Alembert, a noted scientist and mathematician, started working on the Encyclopedia in 1745. Among the many responsibilities of creating such a big compilation of knowledge, was finding authors to write the Encyclopedia. To accomplish this task, Diderot and d'Alembert employed the services of some of the greatest minds of the time: people like Voltaire, Turgot, Quesnay, d'Holbach, Montesquieu, Buffon, and Rousseau. Robert Morrissey summed up the philosophes efforts by saying that, "these great minds (and some lesser ones) collaborated in the goal of assembling and disseminating in clear, accessible prose the fruits of accumulated knowledge and learning." (2) The Encyclopedia itself consists of seventeen volumes with a total of roughly 72,000 articles and 16,500 pages. According to Morrisey, "the typical article includes the head word, its part of speech and gender, the category of knowledge to which the article belongs (e.

Color Essays -- essays research papers

Color is sensed when white light bounces off an object and is reflected into the eye. Objects appear different colors depending on what colors were absorbed and which were reflected. Color is "seen" by the rods and cones in the eye. Cones detect color and rods detect black, white, and shades of gray. People who cannot see colors properly are colorblind. There are many different kinds of colors and they are classified in many different ways (The World Book Encyclopedia p 818, 819). The eye consists of many parts. The part of the eye you can see when you look at someone consists of four parts. The colored part of the eye where the light enters is called the iris. The white part around the iris is the conjunctiva and episclera. This part also contains blood vessels. The cornea is the clear covering of the iris and pupil. The cornea contains no blood vessels. The lens is located behind the iris. The lens is used to focus, as in the cornea, but the lens can move. The retina is responsible for telling the brain what a person is seeing. They determine all the different parts of what is being seen. It then codes them to electrical signals for the brain (Cassel p 4-10). Rods and cones are in the retina. There are three kinds of cones. Each cone can sense a different color. Rods are used when a person is in dim light (Hubel p 162). The optic nerve is what sends all these messages to the brain (Cassel p 261). Sometimes people have difficulty telling colors apart. This is called colorblindness (Webster's Dictionary, p 281). Sometimes colorblindness is hereditary. Other times there is a problem with the message reception from the optic nerve. Another problem can lie in the retina. People can have trouble recognizing colors because of certain drugs. People are diagnosed as being colorblind by taking tests. They look at different colored numbers that are in order by their color. This way they can be diagnosed as being colorblind in certain areas (Cassel p 52). A person can have different extents of colorblindness depending on what the problem is. A person can be colorblind because t... ...ht or white the colors will appear reversed. Red becomes green, and yellow becomes blue (The World Book Encyclopedia p 820, 819). A quote about afterimages was given by Johannes Ilten: "It has been psychologically proven that the afterimage as well as the simultaneous effect show the strange and so far inexplicable fact that our eye demands for a given color it's complementary completing and produces it on it's own if it is not provided" (Tritten p C43). Color is a product of many different things. We physically see color by the light hitting the retina and being absorbed by the rods and cones. Colors are distinguished by sorting them into categories. These could include tint, shade, tone, chroma, value, or hue. It could also be determined by whether a color is primary, secondary, intermediate, or complementary. The illusion of different colors can be created by the colors around a color or placing bits of color very close together as in a television. Afterimages create the opposite of colors. All color is a product of light. Without light, we would only be able to see in black and white (The World Book Encyclopedia p 818, 819, 822, 823).

Determination of the timing of activities and the total float The earliest start time (EST), the earliest time at which the node could be reached, and the earliest finish time (EFT), the latest time by which the node must be reached if the project is to finsh by its required completion date, are produced by a forward pass through the network. The first step of the forward pass is calculating the earliest start time, commencing from the unique project start node and finishing at the unique project completion node. The first task of the project is A, hence the earliest start time of task A may be set to zero since no information has been given as to the starting day of the task. The next step is determining the EFT, which is calculated by adding the EST to the duration of the task. Given the duration of every task, the proces of calculating the EFT of every task is quite straight forward assuming that the EST of every task is the EFT of the previous task. However, when it comes to a merge activity the largest value must be taken. The latest event times, refering to the latest start time (LST) and the latest finish time (LFT), are the times when a particular task may commence without delaying the project duration and when the particular task may be completed without delaying the project duration. Usually such times are required when the project has an established target finish date. The latest event times are calculated using the backward pass technique. Such technique begins by determining the latest finish time of the last task of the project completion and works backwards to the start node. Since no inforamtion has been given regarding the target finish date of the project, the LFT of the project is equal to the EFT in which the project can be done. Hence, the LST can be calculated by subtracting theduration from the LFT. Working backwards, the LST of the previous task is to be the EFT of the task with the determined EST. It is important that when it comes to a merge activity the smallest value must be take n. Once the LFT of every task is completed the total float can be calculated by the following formula: Total float = latest time of finish event – earliest time of start event – duration 3. The project duration and the critical path The project duration was determined by adding the EST of every task to the durtation of every task carried forward from one task to another. Hence, the longest path determines the duration of the project and therefore establishes the critical path since the longest necessary path through a network of activities when respecting their interdependencies is considered to be critical. Furthermore, the critical path may also be determined as the path with the least float. In fact, the critical path determined above has the least float (0) and the longest duration of the project (52 days). 4. The earliest date the project can be completed given the starting date – Monday 7th May 2012 The earliest finishing time of the project as established in the diagram is that of fifty two days. Given that the project can be completed using a five day working week, therefore it will take ten weeks and two days to complete  the project. Calculating the weeks and days from the 7th of May 2012, the earliest date in which the project can be completed is on Tuesday 17th July 2012. 5. The effect on the duration of the whole project if: a. Activity F is delyaed by one day. The delay in activity F will not affect the duration of the whole project as such because the increase in duration will not exceed the total float of activity F, therefore does not exceed the duration of activity H which forms part of the critical path. Activity F can only affect the duration of the project if it delays by five days as it will surpass the amount of days that the activity is allowed to float. b. Activity N is delayed by one day The total float of activity N is that of eight days. Therefore, the amount of days that activity N will be delayed does not affect the duration of the project. In this case, in order for the duration of the projet to be effected the delay time of activity N has to be of nine days as it will surpass the duration of activity M which is part of the critical path. c. Activity O is completed one day early Given that the activity forms part of the critcal path, therefore the duration of the project will be affected not only by being completed early but also if the activity had to delay since the total float is that of zero. In this case, since the activity will be carried out one day sooner than expected, the project will be completed one day early and the duration of the project will be that of fifty one days instead of fifty two days. 6. The limitations of Network diagrams In project managent network diagrams have several advantages when it comes to scheduling projects. One major advantage is that it helps project managers identify the most important activities which may affact the project schedule. However, such diagrams have also limitations to their use in scheduling a project. For large projects a network diagram may not be the ideal scheduling technique because of several activities and dependency  relationships that can make the diagram complex to carry out and difficult for other employees to understand. Furthermore, if the plan of the project changes during the completion of the project, the precendence network will have to be done all over again. In addition, such diagram therefore, may be considered as a time consuming technique. The techniuqe may also take too much to identify all activities and inter-relate them to multiple project paths. Network diagrams may also not be suitable for first time projects because if project cannot be broken down into distinctive activities with known duratrion for every activity then the precendence diagram cannot be drawn. The most critical factor is the duration because on a new project the duration for certain activities may be difficult to estimate, hence the network diagram may be far from actual. Another limitation of network diagrams is when a shift of resource occurs. When the network diagram encounters re-allocation of resources such as employees being transfered from one acvtiviy to another, the activity completion time may be changed because of stoppage or other relevant reasons and the plan of the project may be disrupted. A network diagram may consist of parallel paths with the same durations. This is considered to be a problem within such diagram because project teams may find it diffuclt to chooose the most critical activities, hence create uncertainty on which path will be the critical path within the project. This may also cause the project teams to disagree as one team may choose one path to be critical and the another team may choose the other path to be the critical path.
