...Explain and defend your preferred theory of happiness In this paper I am going to explain and defend my preferred theories of happiness. I will defend the externalist versions, which are the externalist life satisfaction theory and the externalist desire fulfilment theory. In the first section I will describe the theories. In the second section I will argue that neither affective nor objective theories of happiness are correct. Finally in the third section I will argue that the externalist satisfaction theory is the best version of a desire-based theory of happiness. I will not mention all of the theories, but rather focus on the ones I find the most interesting. Happiness is constituted by desire-fulfilment. It is not only about single desires to be fulfilled, but also about the life-satisfaction as a whole. It is how your life is going on the whole, and how it is satisfying to you. It is not enough only to believe that your life is satisfying, but you must actually be satisfied. We set our own standards for ourselves, which leads to desires that we want to be fulfilled. I believe that Richard Nozick was right to say that a life and self that happiness is a fitting response to, is what we want. We also need to give our life that response. We must correctly believe that out desires are being fulfilled and that this will measure up to our own standards that we set for ourselves. It is not sufficient to be in a psychological state, because the externalists care about more...

...but no machine can replace the human spark of spirit, compassion, love, and understanding.” Louis V. Gerstner, Jr. Materialist Thomas Hobbes once stated that “human beings are in effect just complicated machines”, I disagree with that because unlike machines, humans are having a lot of factors to them that make them unpredictable whereas even the most complicated ones have predictable behaviors,. While humans behave as per their consciousness, machines just perform as they are taught and the most obvious reason is human emotion. This essay will be further expanding on ideas which will be contradicting Thomas Hobbes theory of human machines. “Your intellect may be confused, but your emotions will never lie to you.” Roger Ebert The main thing that makes humans, unlike machines is our emotions, unlike machines emotions are the very core of our being even though our brain makes chemicals that allow us to feel emotions, but that does not define what emotions are. Emotions are what make us weak and also make us strong. A mother’s love for their child can make her cry when they have to live apart for a prolonged period. Again, even the weakest of the weak might rise to the occasion and give a valiant fight with the strongest mass to save his beloved from any form of harm. A machine no matter how complicated cannot use emotions the way a human does, if it to be to keep a memory or even shape their being therefore it is invalid to say humans are complicated machines. “While...

An overview of Morgan's metaphors Morgan (1986) distinguishes eight metaphors for organizations: machine, organism, brain, culture, political system, psychic prison, flux and transformation, and instrument of domination. Each metaphor highlights other aspects of organizational life (see Figure 4.1.). For further analysis, the metaphors can be grouped into three groups: the machine group, the organism group, and the mind group. The machine group only contains the machine metaphor (Paragraph 4.3.). The organism group focuses on the dynamic relationship of organization and environment and contains the organism metaphor and the flux and transformation metaphor (Paragraph 4.4.). The mind group (Paragraph 4.5.) contains two subgroups. The first mind subgroup concentrates on the relationship between the minds of persons and the organization as a social construct; it contains the brain metaphor, the culture metaphor, and the psychic prison metaphor. The second mind subgroup focuses on coordination mechanisms and power plays, and encompasses the political system metaphor and the instrument of domination metaphor. metaphor machine highlights efficiency, quality, and timeliness of production processes in a machine made up of interlocking parts attributes, structures, and development of organizations...

...Theory of Computation [Name of the Writer] [Name of the Institute] Theory of Computation It is a set of rational, systematic, and functional knowledge, focusing on the study of the abstraction of the processes occurring in reality in order to play using formal systems, i.e. through character codes and Instructions logical, recognizable by humans, capable of being modelled on the limitations of devices that process information and perform calculations, such as the computer. For this it relies on the theory of automata to simulate and standardize these processes, as well as to formalize the problems and solve them (Manna, 2012). Automata Theory This theory provides mathematical models that formalize the concept of computer or simplified algorithm and broadly enough so that they can analyse their capabilities and limitations. Some of these models play a central role in several applications of computer science, including word processing, compilers, hardware design and artificial intelligence. There are many other types of robots such as random access machines, cellular automata, abacus machines and abstract state machines; but in all cases it has been shown that these models are not more general than the Turing machine, and then the Turing machine has the ability to simulate each of these automata. This leads to think that the Turing machine as the universal computer model (Manna, 2012). Computational Complexity Theory Even when a problem is computable, it may not be...

...Experience Machine Objection Utilitarianism is a normative moral theory, which suggests that actions are seen as right if they tend to produce happiness to the majority and wrong if they tend to be wrong if they produce unhappiness. This theory can take on the form of act utilitarianism although in this essay, I will be focusing solely on hedonistic utilitarianism as well as an objection to this theory, the experience machine objection. Robert Nozick introduced this objection. Following an explanation of both hedonistic utilitarianism and the experience machine objection I will be critically evaluating the objection. I am going to argue that the experience machine objection is valid against hedonistic utilitarianism because there are people who would not plug into the machine. There are some people who prefer to physically do things not just experience them, don’t want to be limited to a man-made reality and want to make a difference in the world. Two key contributors to the normative moral theory of utilitarianism are Jeremy Bentham and John Stuart Mill. Utilitarianism specifies what makes an action morally correct or incorrect. The theory suggests, “actions are right in proportion as they tend to promote happiness and wrong, as they tend to produce the opposite of happiness.” (Mill 454) It is a type of consequentialism as even though the act itself may be morally wrong, if it produces the best consequences it is seen as a morally right action. For example, killing one healthy...

...There are many theories as to how the pyramids at Giza were constructed. Most experts agree that they were constructed as burial monuments for pharaohs, but “how” these ancient people constructed monuments of such great size without modern machinery is a mystery which is still being debated. The pyramids of Giza are the only surviving Ancient Wonder of the World and one of the most famous tourist attractions in the modern world. They are some of the oldest divine sites in our index and certainly among of the most impressive. The Pyramids of Ancient Egypt were built as tombs for Kings and Queens, and it was the exclusive privilege to have a Pyramid tomb. However, this tradition only applied in the Old and Middle Kingdoms. Today there are more than 93 Pyramids in Egypt; the most famous ones are those at Giza. Even in scientific circuses there are still a lot of theory about how and whom the pyramid was constructed by. According to ancient Greek historian Herodotus, Khufu enslaved his people to build his pyramid. Most of the modern Egyptologists believe it was built instead by tens of thousands of skilled workers, both men and women. There is another theory from Herodotus, which states that machines formed of short wooden planks were used to raise the stones. “After laying the stones for the base, they raised the remaining stones to their places by means of machines formed of short wooden planks. The first machine raised them from the ground to the top of the first...

...History of management Theory of scientific management Scientific management was proposed by Frederick Taylor. He said that “Modern management is the collaboration of people and machines to create value.” In the early days of industrialization the innovators of machines and the innovators of organization and management were engineers. Engineers, after all, were the ones closest to the machines, and this fact placed them at the interaction of workers and machines. He was an engineer at Midvale Steel Company. His direct observations of men at work led him to develop what we would call "motivation" theory. He saw human labor very much analogous to machine work--- something to be "engineered" to achieve efficiency. His theories on management would be promoted worldwide (and maybe took stronger root in Japan than in the U.S. or Europe) and would be controversial at home. If greater economic development through efficient and productive work was Taylor's own view of his work, the growing Labor Movement would see "Taylorism" as exploitive. Organized labor's antagonism to the American popularity of Taylor's work would eventually lead to Congressional hearings and, pretty much, the demise of "Scientific Management". Taylor developed his management theories in his book Shop Management published in 1903, making it arguably the first scholarly work on management. The problem, as Taylor saw it, was that workers were inefficient because: (1) Workers tended to work less than they could,...

...explained difficult economy theory with novel form. The point of the book is about theory of constraint. The main character, Alex Rogo, is working as a manager of a factory. This factory is in jeopardy of lockout. Alex has only three month for showing the possibility of revival. During three month, Alex tries innovation with Jonah’s assistance. According to my understanding of theory of constraint, the first thing to do is finding bottleneck. Bottleneck is a kind of the point that decides the limit of the system. Let’s assume that 10 people are marching in a line. When people are marching in a line, someone in the back would often walk faster to catch up with someone in the front. Also, someone in the front sometimes would wait for someone in the back. Finally, the speed of the marching will be the speed of a guy in the last. Bottleneck in this example is a guy who is marching in the last. Let me give one more example related to service organization. One fast food restaurant recently bought a machine that can increase the productivity by double. So, this restaurant can make more hamburgers in a same time. However, if this restaurant cannot get the supply of material at a same speed of machine, the new machine is useless. Bottleneck in this restaurant is slow supply of material. In this book, the bottleneck was a new machine. Efficiency of this machine is high, but the efficiency was not enough to complete all amount of the work. Next step in theory of constraint...

...Life Span Development and Personality Paper Candace Wiser PSY 300 March 19, 2012 Professor: Kaisa Freeman Life Span Development and Personality During this discovery of a famous person that was in the twentieth century, there are a lot of famous people who did well for the world. First we must know what famous is, famous is “widely known, and honored for achievement” (Merriam-Webster). In this paper we will explore the importance of Marie Curie. We will examine her background, family dynamics, and her influences of heredity and environment psychological development, how her family and support systems have helped to influence her development in growth and adjustment. We will also examine two different theories of personality that best describe Marie, and which theoretical approach best explains Marie’s behaviors and achievements. Marie Curie was born in 1867 in a town called Warsaw in Poland (Jardines, 2011). Marie came from a family that was very small. Her mother died when she was ten years old leaving her to live with her father. When Marie was a teenager she attended a school that was a secret and was called “Floating University” (Jardines, 2011). This school had a secret name that would change regularly for the simple fact of detection by the Russians. The Floating University was a school of physics and natural history. As Marie continued to grow up her father was a science teacher that could not afford to send Marie to college. Marie worked until...

...Testing a Theory Music is one of my hobbies and I thoroughly enjoy playing many different musical instruments and recording my music. I tested a theory once with my guitar processor and my drum machine to see what new sounds I could create. A guitar processor is an electronic device that enables a person to plug in a guitar to the processor to access different sound effects with the guitar such as distortion, flange, wah wah, chorus, delay, and reverb. The drum machine is self-explanatory; it is an electronic device that contains samples of many different drum sounds for a person to create drum beats for songs. I wanted to try a different approach to create new sounds for my music. The research I conducted was listening to other music that used drums with effects on them. I also researched the method of effects that the DJ for the Beastie Boys uses on his turn tables. The DJ plugs his turn tables into an electronic sound effects device similar to my guitar processor and creates some amazing new sounds for the music. I was very intrigued by the way the DJ created the sounds so I wanted to try it for myself. I plugged my drum machine into my guitar processor and plugged them both into a guitar amplifier. I turned all the devices on and started experimenting. Some of the effects on the guitar processor were too noisy for the drum machine and made it sound uncontrolled. There were other effects I tried out that made some very interesting sounds on the drum beats. I took notes on...

...“The question we ask today is not whether our government is too big or too small, but whether it works, whether it helps families find jobs at a decent wage, care they can afford, a retirement that is dignified.” – Barack Obama The world is in economic crisis bringing upheaval throughout the planet. Experts disagree about the best ways to manage paths to stability and prosperity for global societies. The severity of the crisis pressures policy makers toward pragmatism, whatever their ideologies. The big question for every leader involves the effectiveness of their intended actions. Will those actions work? The issues before world leaders range from short-term economic recovery necessitated by the failure of capital markets, to long term survival of humans on the planet earth challenged by climate change and ecological systems, natural resources, and population growth. Potential consequences for world societies and civilizations are enormous. World leaders need confidence that they can predict outcomes when they implement their plans. They cannot manage their policies without prediction. W. Edwards Deming tells us that management is prediction (Rienzo, 1993). How does the human mind find confidence in predictions? From where does confidence come? Confidence comes from knowing the systems we are attempting to manage. The purest expressions of knowledge that we have as human beings are scientific laws. Scientific laws allow scientists to predict outcomes with certainty...
