...production requirements of an open pit mine. The method of analysis was first to determine the cycle time for each truck which led to calculating the amount of each dump truck necessary to meet the waste removal requirement of 70 Mt/pa. Secondly, an expected cost for ten years was conducted on each Komatsu dump truck and cross analysed to determine the most cost efficient option. It was found that the Komatsu 930E-4 had the least expected cost over the ten years. Then cross analysing, each loader with the Komatsu 930E-4 truck, it was determined that the Hitachi EX8000-6 was the most efficient loader for a fleet of Komatsu 930E-4 trucks. Once these were completed, a full haul truck cycle time and expected cost analysis for each year was calculated. It revealed that thirty four Komatsu 930E-4 dump trucks were needed for a single Hitachi EX8000-6 loader. However, the above analysis was limited by the fact that it didn’t account for truck and loader break downs. By taking into account a 10% threshold on the number of trucks and loaders needed it gave some costs accounting for time where not all trucks are operational. This analysis yielded that a fleet of thirty seven Komatsu 930E-4 dump trucks and two Hitachi EX8000-6 loaders would be best suited for the Kangaroo Mining Corporation. The expected costs for both loaders and dump trucks were calculated (refer to table 1.9) and showed that the average expected cost per year of hauling and loading would be $142 613 457/pa and $11 869 288/pa...

...As Rorty (1979) has observed epistemology seems to offer a vantage point, one step removed from the actual practice of science itself, which at first sight promises to provide some foundation for scientific knowledge. By seeking to explain ourselves as knowers, by telling us how we ought to arrive at our beliefs, epistemology is pivotal to science since `proper' scientific theorizing can only occur after the development of epistemological theory. It follows that a key question must be how can we develop epistemological theory--a science of science? Almost 60 years ago Neurath (1944) pointed to the paradox that epistemology confronts: a fundamental problem of circularity, from which it cannot escape, in that any theory of knowledge (i.e. any epistemology) presupposes knowledge of the conditions in which knowledge takes place. In effect, this prevents any grounding of epistemology in what purports to be scientific knowledge, psychological or otherwise, because one cannot use science in order to ground the legitimacy of science. For Neurath, such circularity means that we cannot dump philosophy by detaching ourselves from our epistemological commitments so as to assess those commitments objectively--indeed we would depend upon them in order to undertake that reflexive task. It follows that there are no secure foundations from which we can begin any consideration of our knowledge of knowledge--rather what we have are competing philosophical assumptions about knowledge that lead...

...Sociology - SST2 Introduction Does working overtime increase stress with people? With the ever evolving workforce our economy is shifting from a service/entertainment economy to a product economy. Employers are still looking for ways to get more profit with less people. The typical solution to that is to require overtime of their employees. This topic is significant to the social sciences because evaluates how a stressor, such as working overtime can impact a person’s daily social and family life. As our world is becoming more socially knit people are placing intrinsic value on domestic values such as friendship and family. Employers though are now requiring mandatory overtime as a condition of employment. Consequently, this experiment is being proposed to acquire whether the rise in time at work is affecting the stress level of people thus causing a decline in mental health? Research Analysis Who will the demographic be for the experiment? The demographic will include both genders age group of 22 – 40, who are married or at least have a child. This demographic was chosen because the experiment is targeted to explore whether the overtime is resulting in chronic stress and thus it is required to include both genders. The age group was designed to be broad to eliminate radical variables from invalidating the experiment such as adolescence and physical causes such as menopause from flawing the results. Also this age group represents the statistical age group of people employed...

PREFACE A few words about the overall objectives of the course is appropriate as a starting point. Historically, philosophy was the first form of theoretical knowledge. As a rational theoretical tool of comprehending the world, philosophy arose in ancient Greece in stiff battle with mythology and religious consciousness. It came out to lay the foundation for the evolvement of scientific consciousness and the emergence and development of the sciences - Mathematics, Astronomy, Physics, Chemistry, Biology, etc. In an environment rife with various and varying superstitions and myths, the study of the History of Science and Philosophy of Science becomes crucial, lest science itself falls within the ambit of mythology and superstition and becomes another form of myth even in the hands of the tutored. The study of the History of Science is particularly important...

...important when it comes to making sure the patient is taking medications, attending therapy sessions, and not regressing. Short-term hospitalization would also be advised to assess other possible health issues such as vitamin deficiency, proper follow-up treatments to any injuries past or present, and to remove patient from environmental stresses. In the event that hospitalization is refuted, keeping a nurse on staff at his hope that can provide adequate one-on-one care may suffice. Psychosurgery should only be considered if absolutely necessary (American Psychological Association, 2013). One of the most important scenes in the film that starts the avalanche of stressful events, paranoid delusions, and failed relationships happens after Kate dumps him for another man. Up till this scene, Howard’s obsessive compulsions did not entirely get in the way of his functionality. In fact, his quest for perfection had made him the successful man he had become till this point in the film. Kate walks into his office one night and drops the news of her love for another man. This event opened the floodgate of stress and instability in his life. Howard decides to burn all his clothes, possibly because Kate had touched or been near them, and impulsively calls a manager of his at two in the morning to order new clothes. Howard spends the night looking deeply into the fire, thoughts stirring into a high state of paranoia and stress written all over his expression. In the following scene, Howard is holding...

...The Uppsala Model Internationalisation can be described as “the process of increasing involvement in international operations” (Welch & Luostarinen, 1988, p. 36). At any rate, why a company should internationalize, and how? The fundamental reason for exporting, in most firms, is to make money. However, as in most business activities, one factor alone rarely accounts for any given action. Usually a mixture of factors results in firms taking steps in a given direction. The table below provides an overview of the major internationalization motives. They are differentiated into proactive and reactive motives. Proactive motives represent stimuli to attempt strategy change, based on the firm’s interest in exploiting unique competences (e.g. a special technological knowledge) or market possibilities. Reactive motives indicate that the firm reacts to pressures or threats in its home market or in foreign markets and adjusts passively to them by changing its activities over time. Proactive motives | Reactive motives | * Profit and growth goals * Managerial urge * Technology competence/unique product * Foreign market opportunities/market information * Economies of scale * Tax benefits | * Competitive pressures * Domestic market: small and saturated * Overproduction/excess capacity * Unsolicited foreign orders * Extend sales of seasonal products * Proximity to internationalcustomers/psychological distance | (Adapted from Albaum et al., 1994, p. 31)...

...Running head: MY NURSING PHILOSOPHY My Nursing Philosophy and How Nursing Impacts My Life Liza Guillen Broward College My Nursing Philosophy and How Nursing Impacts My Life In order to fully understand my personal nursing philosophy I had to first begin to research the meaning of the word philosophy. Philosophy: the rational investigation of truths and principals of being, knowledge or conduct (http://dictionary.reference.com/browse/philosophy). Nursing can be defined differently by each individual. The word nursing comes from the Latin word nutricius, which means “nourishing.”(Nursing Today). To nourish is to provide any type of care necessary to promote; maintain life and growth. But what does care really mean? Well caring is defined as “feeling and exhibit concern and empathy for other” (the free dictionary). A nurse incorporates all of these meanings into not only patient care but to a way of life in order to truly believe and live by his or her own philosophy of nursing. Dr, Jean Watson’s caring theory incorporates three main elements of caring into her theory which are carative factors, the transpersonal caring relationship, and the caring occasion/caring moment (Watson, 2001). These elements describe the trusting relationship a nurse must create with the patient, the time and space to do so, and the how a nurse extend beyond their own sense of self to understand and care for others as unique beings. I believe these elements guide nurses to serve...

...Testing A Theory PSY/201 May 12, 2013 A couple of years ago, I decided to test a theory on myself by trying to lose fight while gaining more muscle mass. I have heard so many different theories on how to lose fat while gaining muscle mass, but I could not find a good routine that gave me the best results. Before I began my research, I had to think critical about what was causing me to gain fat, and why my workout routine was not as effective on myself as it was for others. I began to search for credible sources on the Internet, so that I can have a better understanding of the relationship between nutrition and the human body. Once my understanding on nutrition was clear, I then began to do research on fat burning and strength conditioning. After my research was complete, I began to test these theories on myself. I created a chart that kept track of each exercise, the amount of repetitions completed, weight loss or gain, and body fat percentage. I used this chart to compare my before and after results within 90 days, and the end results were stunning. I could lower my body fat percentage, and gain more muscle mass, which was exactly what I wanted. The type of informal research that was used to test this theory was experimental research. According to the textbook, Psychology and Your Life, it tells us about experimental research, which states, “Investigator produces a change in one variable to observe the effects of that change on other variables” (Ch. 1, pg. 33)...

...Scientific Method August 25, 2013 Alfred Porter SCI/230 In the scientific method that I chose to do was the car experiment. The car experiment explains that I am leaving to go to work and I go to start my car and after turning the key nothing happens. By looking under the hood I have three choices of what could be causing the car not to start. It could be the battery cables could be loose, the car needs fluids, or there could be electrical problems. I looked at all the fluids and the fluid levels were fine. Then I think it is the electrical issues and I look at the fuses and changed them out and tried to start the car. I came to the conclusion that the fuses were bad in the car causing the car to not start. My real-life issue that I could have used the scientific method was trying to plant roses and trying to keep them alive. I would plant the roses and water them and even planted them in the sun. I would not try to figure out why they would keep dying. If I would have went through and tried fertilizer and tried to figure out why they kept dying then I would have at least came to a conclusion. If I would have found out how to take care of roses and then started to water them the way they are supposed to be watered and gave the roses the fuel they need to live they would not have died. I would have first seen how to take care of roses. Then I would have measured out the water and how much sun they needed and applied that then tested my theory I could have seen if they would...

...A. Introduction Every woman, whether she chooses to acknowledge it or not, has an innate desire to be desired. Even the staunchest of feminists want to be accepted by other feminists. It goes without saying that we people as human beings, don’t enjoy being disliked and people go to any measure to make ourselves more readily acceptable to others. For everyone, one of the easiest ways to improve confidence and self-image is the use of cosmetics. Cosmetics are products you apply to the body to clean it, make it more attractive, or change the way it looks. A powder, lotion, lipstick, rouge, or other preparation of beautifying the face, skin, hair, nails, and other parts of the body. Cosmetics products are today part of our regular culture and fashion, but that was not always the case. The first human made cosmetics appeared in early modern civilizations some six thousand years ago as the way to enhance the appearance and odor of the human body. In the ancient Egyptian time they use to create the world’s first cosmetics to the scientifically advanced products of today that can do everything from hide pores, smooth complexions, and turn pale green of your eyes a vivid shade of emerald. Make up has been an integral part of human kind for thousands of years. Over the centuries, women used burnt matches to darken their eyes, berries to stain their lips and young boy’s urine to fade their freckles. They even swallowed ox blood in some misguided attempt to improve...

The periodical is current because it was sourced on 9/22/2012. It is authoritative because it the author is a consultant for New Scientist based in London.

...Scientific Method Sharon Childers Unit 1 Individual Project May 5, 2013 Biology American Intercontinental University Biology is the study of life. When studying Biology one will study the way organisms live and their lives. How are humans created? How are cell formed? What is DNA made of? All of these questions are some form of Biology. Even the color of certain birds is a part of Biology. When dealing with the Sciences you will come across the Scientific Method. This method consists of: Question, Hypothesis, Research, Experiment, Analysis and Conclusion. Below we will discuss a question and complete the steps of the Scientific Method to come up with an answer to the question. Question Do ruby-throated hummingbirds prefer some colors more than others when visiting flowers? Hypothesis In my opinion I believe hummingbirds prefer bright colors opposed to darker colors. The hummingbird has a red throat so considering that I would think they prefer red or something similar to red when it comes to picking flowers to visit. Research Ruby-throated Hummingbirds are primarily in the United States. These small birds are hard to find in the sky because they are only 2-3 in and can flap their wings 53 times in one second. That’s kind of hard to believe or even imagine. When it comes to the type of feeder a hummingbird feeds on doesn’t really matter. They tend to eat from any kind of feeder. When it comes to flowers they prefer, red and yellow are their preference...

...------------------------------------------------- The progression of the three stages[edit] (1) The Theological stage refers to explanation by personified deities. During the earlier stages, people believe that all the phenomena of nature are the creation of the divine or supernatural. Men and children failed to discover the natural causes of various phenomena and hence attributed them to supernatural or divine power.[1] Comte broke this stage into 3 sub-stages: 1A. Fetishism - Fetishism was the primary stage of the theological stage of thinking. Throughout this stage, primitive people believe that inanimate objects have living spirit in them, also known as animism. People worship inanimate objects like trees, stones, a piece of wood, volcanic eruptions, etc.[2] 1B. Polytheism - The explanation of things through the use of many Gods. Primitive people believe that all natural forces are controlled by different Gods; a few examples would be God of water, God of rain, God of fire, God of air, God of earth, etc.[3] 1C. Monotheism - Monotheism means believing in one God or God in one; attributing all to a single, supreme deity.[4] (2) The Metaphysical stage is the extension of the theological stage. Metaphysical stage refers to explanation by impersonal abstract explanation. People often tried to believe that God is an abstract being.[5] They believe that an abstract power or force guides and determines events in the world. Metaphysical thinking discards belief in a concrete...
