God Exists Essays - Epistemology, Ren Descartes, Thought

God Exists The existence of God has been a question since the idea of God was conceived Descartes tries to prove God's existence, and to show that there is without a doubt something external to ones own existence. He is looking for a definite certainty, a foundation for which he can base all of his beliefs and know that they are true. Descartes' overall project is to find a definite certainty on which he can base all his knowledge and beliefs. Descartes attacks the principles that support everything he believes with his Method of Doubt. The Method of Doubt is Descartes' method of fundamental questioning in which he doubts everything that there is the slightest reason to doubt. Think about it like this. Almost everything you believe to be true comes from the senses or through the senses. However, the senses are sometimes deceptive. Since the senses are not completely trustworthy, it is irrational to place complete trust in them. However, it is no small leap of faith to presume that everything our senses tell us is false. In fact, it seems almost absurd to say such a thing. Nevertheless, as Descartes points out, we have dreams regularly and in these dreams, everything we experience is a figment of our imagination, or at least not real in the physical sense. So, it is reasonable to doubt everything our senses tell us, for the time being. Now, using similar logic, we can say that everything we have learned from physics, astron omy, medicine, and other such fields are all doubtful. Descartes even believed we could say that such simple, logical statements as 2+3 = 5 or a square has 4 sides could be conceived to be false. Since I judge that others sometimes make mistakes in matters that they believe they know most perfectly, may I not, in like fashion, be deceived every time I add two and three or count the sides of a square? We are now at the point where we are doubting everything - the world around us, that we have a body, and anything else that we could possibly believe. Perhaps I even doubt that I exist myself. In doing this, I am in the act of doubting. How can I doubt something if I do not exist? Similarly, maybe I am deceived into thinking I do not exist by some other entity. Then I must exist for it is I who is being deceived. This is the basic premise of Descartes' famous Cogito Ergo Sum - I think therefore I am. Here Descartes is not saying anything about what we are here, just that we are. Next, his goal is to find out exactly what he is. Well, Descartes states, if I exist, for how long do I exist? I exist for as long as I think, and if I cease to think, then I shall also cease to exist. Therefore, I am nothing but a thinking thing - that is, a thing that doubts, understands, affirms, denies, wills, refuses, and that also imagines and senses. Although saying he is all of these things is indeed a bold statement. Descartes feels that in his attempt to prove that he exists he has done all of those things, therefore they must be a part of what he is. Decartes goes on to prove the existence of God. He begins this by stating that nothing can be created from nothing, and that the less perfect can not create something more perfect or better than itself. He explains that he knows he is not perfect because he doubts, and knowing is more perfect than doubting. From that he determines that within him lies this idea of a perfect being, and that he is incapable of coming to such an idea by himself. If there is an idea in our minds that we didn't create, something else created it. He saw nothing in nature that would qualify as superior in the sense that he had stated, so he determined that the only other logical answer was that God placed it in him, therefore, God exists. Berkeley would argue that Descartes is wasting his time by trying to discover what must be absolutely true in the

Woody Guthrie essays

Woody Guthrie essays For my project, I chose to go look at the exhibit, The Life and Legacy of Woody Guthrie, at the J. Wayne Stark University Center Galleries. It told about his life story, and presented many of his famous works of art. Woodrow Wilson Guthrie was born in the small town of Okemah, Oklahoma on the fourteenth of July in 1912. His grandparents moved to Oklahoma trying to seize the opportunity to seize land from the Indian Territory. In his lifetime, Woody experienced and saw much hardship, which he reflected through his artwork, music, and poetry. For example, at the age of only fourteen, Woody was living on his own. Using the hymns and spirituals he learned, Woody added what he learned in the folk tradition from people he met on the road. He also lived during the period of the Great Depression, which presented starving families and much injustice. Woody and many Americans wondered how all of these horrible things could go on in the country proclaimed to be the land of freedom. Many families were starving as plenty of food sat behind the fences in the fields left to rot. All of this, Woody expressed through his work, as he was not merely just an artist, but an avid activist as well. His life p rematurely ended when he was hospitalized being diagnosed with Huntingtons disease, which also was the cause of death to his mother. However, the impact that he laid upon American soil was so significant as to this day he is still acknowledged in every fight, and battle for fairness, and equality. The exhibit showed many of his paintings, poetry, and music he produced in his lifetime. His artworks were direct past events he personally experienced, from the Black Blizzard to Starvation Disease. His artwork was not beautiful, fancy, or done with much detail. However, Woodys ability to directly show the events so blatantly is what makes his works so powerful. For exa...

Critical Thinking - Essay Example She made a decision and took action as a result of the decision. She immediately reported to the HR the flaw of the system and Tanya’s behavior. In my case, I took a stand when my I saw my classmate cheating in one of our exams during middle school. Although that classmate is a neighbor, I reported it to our teacher. The issue is cheating during examinations. My classmate used a small piece of paper that contained facts about the exam. I immediately called the attention of the teacher during the examination by writing on my test paper about what I saw. There was a need to suspend judgment for a few minutes before I told the teacher since I had to be certain that she was really cheating. Nevertheless, the decision to turn her in was deliberate since it would be unfair for the rest of the class to let her cheat since we all studied for the difficult exam. My position then was purely logical, we get what we deserve so I was just being objective. My advocacy then was not about honesty, it was all about reward for hard work. My action is a consequence of my decision to not tolerate cheating during examination since we all need to study to get the grade we deserve. Tama, M.C. (1989).

The Chinese Decision to Enter the Korean War Essay

The Chinese Decision to Enter the Korean War - Essay Example China's intervention in Korea cannot be ascribed simply to wanting to maintain the semblance of balance of power, "a theory of state behavior [that] explains and predicts how states respond to threats posed by a potentially dominant, revisionist and aggressive state"1, based on the assumption that states seek to, "maximize their power in order to survive in a competitive international system".2 US presence in the Asian region led to China and the US pursuing purely security related strategies that were mutually exclusive, inadvertently generating mutual hostility. Similarly, Chinese responses cannot be generalized into the Chinese merely wanting to secure their national interests without taking into consideration many other factors such as leadership challenges, domestic imperatives, and political consensus amongst domestic bureaucracies that can impinge upon foreign policy. The general understanding and belief is that China's foreign policy has been shaped primarily by external stimulus with domestic factors playing only a marginal role. However, the inability of existing theories to fully explain the reasons for China's entry into the conflict signifies that we must look at explanations that go beyond functional concepts of International Relations but also look more closely at internal factors and domestic compulsions. Students of international relations a... This is particularly relevant in the context of the Korean War, when one recollects that China was then emerging from the throes of a protracted civil war and that the People's Republic of China had been formally declared less than a year earlier, in October 1949. When the internal polity of a country is in a state of flux, any government which is seen as defending a nation's interests will only emerge stronger. China's entry into the Korean conflict can therefore, largely be seen to emanate as a result of the CCP converting a external 'threat' into an opportunity to consolidate its position internally. Korea was annexed by Japan in 1910 and remained under Japanese occupation until the end of World War II. In August 1945, the Soviet Union and the United States decided to oversee the surrender of Japanese forces to the North and South of the 38th parallel respectively. This was to be a temporary arrangement, with a united Korea the ultimate aim. In the interim, the US and the Soviet Union established governments in their respective zones that were sympathetic to their political ideologies. The US installed Syngman Lee in South Korea, while the Soviet Union backed North Korea Kim Il-Sung, with both wanting a unified Korea, under their own system and stewardship. However, North Korea was bolstered by Soviet advisors and military equipment was better prepared to seize the initiative. The North Korean attack across the 38th Parallel in June 1950 was a resounding success North Korea could not capitalize on their gains. North Korea failed to accomplish two crucial tasks, namely the total annihilation of the South Korean army and the

The Effect Of Increasing Mass On Acceleration Environmental Sciences Essay

The Effect Of Increasing Mass On Acceleration Environmental Sciences Essay Mass is a property of matter equal to the measure of an objects resistance to changes in either the speed or direction of its motion. The mass of an object is not dependent on gravity and therefore is different from but proportional to its weight. Speed is the time rate of change of position of a body without regard to direction. Linear speed is commonly measured in such units as meters per second, miles per hour, or feet per second. Velocity represents speed but according to the bodies direction. We can calculate from a distance time graph with dy/dx.    Acceleration describes the time rate the velocity is changing at. The relationship between acceleration and velocity is similar to the relationship between velocity and displacement. Acceleration is a vector quantity, so a = 0 for uniform velocity. The entity is thought to be uniformly accelerated if the constant of a is a non-zero. The average acceleration of an entity is defined as: Average acceleration = change in velocity / time taken In my investigation, I will aim to find the effect of increasing mass on acceleration. Method I will do this be setting up an apparatus which will measure the rate of acceleration. First, I will set up a height of 15cm and length of 227cm ramp. At this height, I do not have to apply a force to the trolley to accelerate the trolley because it will be able to slide down due to the force of gravity. This way, the force of gravity can be kept constant. Then, I will use a ticker machine and ticker tape to measure the rate of acceleration. I will stick the ticker tape into a trolley of 850g and let it fall. Each 10 mark on the ticker tape represents 0.2 seconds so I will cut the ticker tape in strips of 10 marks. By plotting the strips onto a graph, it would tell us the speed in which the trolley travelled. From this, we can calculate the acceleration of the trolley: Acceleration = final velocity initial velocity =   Ã¢â€š ¬Ã‚  Ã‚ Ã¢â‚¬Å¾ v   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Time  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     t I used a ticker machine to calculate the rate of acceleration because it would show the rate in which acceleration changes. If we just timed how long it takes for the trolley to reach the end of the trolley, it would only give us the average acceleration. It would not be possible to measure the change in acceleration. I chose 15cm height ramp because from our preliminary results we found the marks on the ticker tape appeared most clearly at this height. Previously, the height of the ramp was 43cm and it was too high of the marks to appear clearly and because of this, my results werent as accurate. The average angle of the ramp was 3.87  ÃƒÅ'Ã…  . I chose this angle because I found from preliminary results that if the angle is too high, the marks on the ticker tape would not print accurately. Before, the average angle was 10.7  ÃƒÅ'Ã…   and we found it difficult to read the ticker tape. I clamped the ramp in place because this way, the height of the ramp is less prone to change so its acceleration will only be affected by the mass of the trolley. This will make our results more accurate. I added 400g of mass each time because from preliminary tests, I found that the ranges of the results were too close to each other to see a correlation when we added 100g each time. So to make the results more clear to see if mass affects acceleration, I decided to add more weights. This way, there would be a greater difference in the results and it would be clearer to distinguish a correlation. I chose a trolley of 850g because the trolley was light weight and the wheels were fairly smooth. Because it was light weight it would be easier to add mass on and be less affected by friction. Because the wheels were smooth, the frictional force would be less. This will make our results more accurate. To keep my investigation fair, I will only change one factor- the trolleys mass. I will keep everything else the same such as the height of the ramp and the ramp itself because these factors would affect the results if theyre are not kept the same. Prediction I predict that the mass of the trolley will not affect the rate of acceleration. This is because according to Galileos laws of motion, all bodies accelerate at the same rate regardless of their size or mass. For example, the fact that a feather falls slower than a steel ball is due to amount of air resistance that a feather experiences (a lot) versus a steel ball (very little). Also according to Newtons second law, the acceleration and gravitational force of a body is directly proportional to each other. He adds to Galileos law of motion by saying everything falls at the rate of 9.8m/s. He calculates this by: (F=force, m=mass of Earth (), a=acceleration, r=radius of Earth, G=gravitational constant (6.7-10†¾Ãƒ ¡Ã‚ ¶Ã‚ ¥Ãƒ ¡Ã‚ ¶Ã‚ ¥ Nm ²/kg ²), g=gravitational force) If F=ma and F=gm ma=gm So you can cancel m to get a=g Factors which affects the rate of acceleration: Friction would affect the rate of acceleration because it increases the reluctant force by griping on the wheels and increasing the time it takes for the wheels to turn. Sometimes this can be good because it makes cars easier to manoeuvre. To show that friction affects the acceleration, we could carry out the same experiment, but instead of changing the mass, we would add different materials to the ramp. This would show us how surface area affects acceleration. The gradient in which the body is travelling would also affect the acceleration because some of the force would go into the other direction instead of going down so it experiences more drag. This would increase the time it takes for the body to fall. We can show this in our experiment by increasing the angle of the ramp instead of mass. The shape of the body will also affect its acceleration because the more wide it is the more air resistance/ drag it will have. Air resistance slows down an object because it opposes a force in the opposite direct to gravity, so the force of gravity is less. We can show this by changing the size of the surface area of the trolley but keeping mass the same. Results Average Acceleration From the graph, we can see that generally, as the mass increases, so does the acceleration. Theres a steep linear gradient from 850g-1650g, and acceleration increased by 4.82ms†¾Ã‚ ². Even though the actual results shows a decrease in acceleration between 1650g-2100 by 0.53 ms†¾Ã‚ ², the line of best fit tells us it is actually increasing. Overall, acceleration increased by 0.2m/s†¾Ã‚ ² every 100g that was added. Average Speed The average speed shows as the mass increased, so does its speed. There is a linear gradient between 850g-1250, and the speed increased by 1.7cm/s. From 250g-2050g, the speed decreases by 0.75cm/s. However, from 2050g-2450g, the speed increases again by 0.66cm/s. Overall, although it decreases, the line of best fit shows that it increases greatly from 850g-1250, then the line starts levelling out from 1250g-1450g. Accuracy Rating To measure the accuracy rating, we drew a gradient line from our initial speed to our final speed in each set of data. If our results were accurate, the line should correspond with our results since the speed of the trolley should have been fairly constant. To calculate this, we counted the squares the tape was above the drawn line or below it. This would give us an estimation of how precise our results were. The accuracy rating generally shows that as the mass increases, the level of accuracy also increases. This graph shows the higher the number of accuracy, the lower the level of accuracy. There is a huge fall in the number of accuracy rating between 850g-2050. It went from 38.67 to 29, a difference of 9.67. From 850g-2050g, the number of accuracy kept decreasing and overall, it decreased by 14.3. However, from 2050g-2450g, it increased by 2. This may be because as mass increases, the bigger the friction is on the wheels. The larger the friction the better the wheels can grip on the surface so travels more accurately and is less likely to skid. This tells us, the results of acceleration and speed for 850g is very likely to be an outlier because the level of accuracy is very low. Comparison: When we compare the results of the average acceleration to its speed, we can see its directly proportional because as the acceleration increased, so did the speed. This is because acceleration shows how speed changes. When we compare the level of accuracy to the acceleration and speed, it tells us the results for 850g is very likely to be anomalie and possibly 1250g as well. If that were true, the graphs would show that there is no connection an objects mass to its acceleration. This would prove Galileos law of motion and Newtons second law that the rate of acceleration is constant and is not affected by size or mass. However, our experiment does prove their theories are correct because our experiment shows that the less resultant forces oppose to gravity (more friction in this case), the faster the body accelerates and does not depend on its mass. Evaluation I believe my experiment went fairly well because I felt I could justify the reasons why I obtained these results and although I have some anomalies, most of the results were fairly accurate. However, there were some flaws in my experiment such as: I found it hard to set off the trolley at the same position on the ramp each time because it was not marked clearly. I did not wipe/grease the ramp after each experiment, doing this would have make the friction of the ramp more consistent When I plotted the strips of ticker tape on the graph, I did not line them accurately on the squares. This made some of my results inaccurate. Improvements To improve my experiment, I would have made the height of the ramp lower because it would experience more friction for the wheels to grip on. I would have also used trolleys with different masses but the same density. This way, drag/air resistance be more likely to be the same so there would only be one factor affecting the results. This would make out results more accurate. To obtained accurate results, we can perform this experiment in a vacuum. This is because in a vacuum, you would not experience any resultant force as you do in Earth so you could accurately calculate acceleration. However, we can only experience a vacuum in space. In earth, to decrease resultant forces, we can carry out this experiment in: Under water High altitude Air tight conditions

Patty Herst vs. Connie :: essays research papers

Patty Campbell Hearst Vs. Connie   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Where are you going, where have you been?† is a story about a young teenager named Connie that is rebelling against her parents and discovering her sexuality with older boys. No one can really control Connie; she sneaks around and hides what she does from her parents. Her character reflects a person named Patty Campbell Hearst who was kidnapped in the seventies. I am going to compare these two people.   Ã‚  Ã‚  Ã‚  Ã‚  The story of Patty Hearst is a bizarre one. First of all Patty is the granddaughter of the famous newspaper publisher William Randolph Hearst. That’s why she was kidnapped in the first place. She was taken on February 4th 1974 by an activist group who called themselves the Symbionese Liberation Army. This uncanny group was trying to wage a war on those of status and money. When the SLA abducted Patty there was media frenzy over it. Anyway she went missing for two months then something most unexpected happened. She appeared on a surveillance tape helping the SLA rob a San Francisco bank. This bizarre twist of events is still being debated today. Why would a girl join her captors and help them in crime?   Ã‚  Ã‚  Ã‚  Ã‚  Now I’ll compare how Connie resembles this concept. During the story Connie keeps going farther and farther with older and older boys. Keep In mind that she’s a young girl much like Patty Hearst. Toward the end of the story a much older man named Arnold Friend arrives at her doorstep attempting to seduce Connie into â€Å"going for a ride† with him. She was alone and he knew it. At first she kept telling him to leave but he started getting under her skin. He just kept trying to reassure her that he wouldn’t hurt her and that he was her friend. But Connie knew from the start that he was a dangerous man and that something wasn’t right. He knew all sorts of things about her. Arnold told her exactly where her family was at the time they we’re talking without her saying anything. It was obvious that he’d had an eye on her. However Arnold Friend still hadn’t convinced Connie to go with him. Then he started leaving hints that he was going to take her. For instance he said: â€Å"Connie, don’t fool around with me, I mean don’t fool around.† Eventually he was really getting to her and she threatened to call the police.

Blood clotting enzyme Essay

Serine protease proteins are important enzymes involved in the process of blood coagulation. Blood coagulation is an importance defense mechanism that prevents the host mammal organism from losing excess blood or from forming unwanted blood clot. The process of coagulation can be initiated by both intrinsic factors and extrinsic factors. A cascade of event is followed which activate these enzymes; normally the enzymes are inactive state a condition called zymogens. Zymogens by their virtual condition of being inactive prevent unwanted blood clotting which may have a far reaching consequence such as thrombosis. Blood clotting in a series of processes, in which the zymogens’ need to be activated by reacting with its glycoprotein co-factors. Among the serine protease is the thrombin enzyme factor five (v) responsible for clearing clot in the blood. The enzyme is usually present circulating in plasma which is made up of a single monomer chain, it life span can range from 12 to 36 hours. In human the main regulator in blood coagulation is erythrocytes leukemia cells which activate adenylate cyclase, the process is reversible by the interaction of Aalpa-thrombin with glycoprotein while b alpha enhance the platelets interaction which initiate the proteolytic process. Fibrin-bound thrombin is cleaved by thrombin at a very specific site at the extracellular N-terminal, PAR-1 regulates a number of endothelial cell biology, vascular development but more so is a mediator of thrombin signaling. The human thrombin consist of two gamma chains namely the gamma A and gamma’ the final stage of coagulation of mammalian blood involves the cleavage of the four arginine and glycine bond. Binding studies shows both fibrin 1 and fibrin 2 with low affinity to the E domain and high binding affinity at the extreme end of 408 to 425 on the gamma chain The mode of action involves conversion of fibrinogen to fibrin by breaking the bonds in the fibrinogen at a precise position of arginine and glycine where the fibrin peptides are released. The serine proteases require restructuring itself in order to fit the key and lock model. The glycine at the position five is highly conserved because it is the one which occupy the active site which is determine by the acryl group during the substrate conformation. Asparagines 189 help the enzyme to easily recognize the substrate. The active site is entirely made of histidine 57, asparagines 102, serine 195 and serine 214. The reaction on many a times prefers position 1 to position 4 during remodeling, therefore the type of protein presence to a large extend determine the kind protease and also the kind of cleavage to take place. Thrombin activation is regulated by pentapeptide of the COOH terminus of the factor (v) heavy chains. Thrombin and thrombin receptors is another regulatory point where they both posses strong protective barrier and at the same time cancerous cells were eliminated by apoptosis. A study carried out using mitochondrial membranes which were depolarized using attenuated Catalase lead to controlled cell death. Statistical finding indicate that 30% of the population carried world wide indicated that activated peptide segment at position 4 of factor eight caused a substitution in V34L after binding the structure and analyzing the interaction according to (Brenda 2010). The switching of receptor is PAR-1-dependent signaling specifically to thrombin resulting inhibition of adhesion cell surface which activate thrombin the ligand occupancy position switches the protease receptor by signaling specifically to the thrombin. Human cell in culture indicated low amount of thrombin and receptor PAR-1 agonist induced strong anti-inflammatory activities which was secondary effect of the low concentration of thrombin after activation by P13 kinase and PAR-1. Thrombin like other enzymes is very specific in the binding domain and the insertion loop which is determined by the residues involved in ligand binding as result of interaction glycoprotein and protease receptor on the platelet membrane. This uniqueness makes it very efficient in it task according to (Webert 2006). The enzyme play vital role in homeostasis, cell differentiation, thrombosis and activation of blood cell types, on exposure to phosphatidylserine on the outer surface the platelets were stimulated. A study done using heparin indicated an overlap of the active site, which was attributed to the interaction of thrombin and the gamma peptide chains to the external and the interaction to the active site in close proximity to the Na+ of the substrate. The role of the enzyme can be explained in terms of NA+ binding to thrombin on the basis of prothrombotic and procoagulant. The cascade is a continuous cycle of events that are activated by two factors ,factor (ix) and factor (viii) to form tenase complex which is discontinued by down regulation that occur in the following mechanism which include; serpin (serine protease inhibitors) which function to degrade thrombin and other activation factors, it can also be regulated by protein C where thromodulin bind to it and is inactivate in the presence of protein S, limiting the action of tissue factor by the tissue factor pathway inhibitors by inhibiting excessive TF mediated activation of factor (ix) and factor (x), plasmin help to degrade fibrin hence preventing more fibrin being formed and lastly but not the least regulation through adenylate cyclase pathway by inhibiting platelet activation by decreasing cytosol level of calcium which ultimately result to decreased release of granules which are responsible for the activation of more platelets and coagulation cascade. In conclusion the work play by thrombin enzyme is of paramount importance considering the complexity of the enzyme kinetics involved in the human body.

Tax Hikes and the 2011 Economic Collapse

Tax Hikes and the 2011 Economic Collapse Summary of the Article Changes in the government policies are the driving force behind the society’s change in the volume, composition and location of their income. For instance, businesses and people have been noted to change the location of their income on the basis of tax rates and incentives.Advertising We will write a custom report sample on Tax Hikes and the 2011 Economic Collapse specifically for you for only $16.05 $11/page Learn More According to a report by the U.S Treasury in 2004, the receipt of wages and bonuses was accelerated between 1992 and 1993 by the taxpayers who received a high income. This was as a result of an anticipated hike in tax from 31% to 39% (Arthur 1). The same happened in the following year due to the expected increase in Medicare taxes. From then, the tax rates in the U.S have been noted to be increasing in almost all sectors of the economy from the income taxes, health care taxes to the state and local taxes just to mention a few. However, if this trend continues to surpass the tax boundary, then there is a possibility of experiencing a recession in 2011. Analysis In this article, Arthur Laffer, warns on the trend on the taxation rates in the United States. Given the trend, he foresees a recession taking place in 2011 if at all action is not taken. This is because, people normally make their income decisions based on the tax rates imposed by the government. Therefore, in case of high tax rates imposed, people will be forced to relocate their businesses in other regions of the world where the tax rates are reasonable. If this happens, the economy of United States will be greatly affected. This happens because the profits of any business enterprise and corporations are considered as a share in the Gross Domestic Product of the state (Arthur 1). Thus, if the businesses are to relocate to other regions, their profits will be incurred in those regions and not in the U. S hence a fall in the Gross Do mestic Product. The contributions made by Arthur Laffer in this article are worth appraisal. By giving his side of story on the tax related issue, he not only informs the general public of the state’s economic position but also provokes the government’s intervention on the same. He does this by comparing the current economic situation of America with the position it was during former presidents such as Ronald Reagan which he notes that Reagan’s actions are a mirror images of the current president Barack Obama.Advertising Looking for report on business economics?

Application The information in this article is applicable in almost all sectors of the economy because of the mare fact that tax is inevitable. From the consume r to the producer to the state, all have a share to contribute in form of taxation. Therefore, being informed of matters related to taxation has many advantages to all stakeholders. For one, the government is alerted to take precautionary actions and entrepreneurs informed of the danger ahead, while the consumers are informed of the economic position of their state. Conclusion From the above discussion it is clear that this article is of great benefit to the entire society which is made up of the taxpayers. It is also a great contribution to the macroeconomics course since taxation is an everyday activity. Laffer, Arthur. â€Å"Tax Hikes and the 2011 Economic Collapse†.

Johnson Behavioral System (JBS) Model Essays - Nursing Theory

Johnson Behavioral System (JBS) Model Essays - Nursing Theory Johnson Behavioral System (JBS) Model In this paper, I am going to summarize the Johnson Behavioral System (JBS) Model (Johnson, 1980, 1990), explain the perspectives for nursing practice, and explore its applicability in nursing practice. First, I am going to talk a little about Dorothy E. Johnson the nurse that wrote the Model. Dorothy E. Johnson was born August 21, 1919, in Savannah, Georgia (Lobo, 1995). She received her A.A. from Armstrong Junior College in Savannah, Georgia, in 1938; her B.S.N. from Vanderbilt University in Nashville, Tennessee, in 1942; and her M.P.H. from Harvard University in Boston in 1948 (Conner, Harbour, Magers, and Watt 1994). Johnson was an instructor and an assistant professor in pediatric nursing at Vanderbilt University School of Nursing from 1944 to 1949. From 1949 until her retirement in 1978 and subsequent move to Key Largo, Florida, she was an assistant professor of pediatric nursing, an associate professor of nursing, and a professor of nursing at the University of California in Los Angeles (Conner et. al. 1994). In 1955 and 1956 she was eligible to go on a sabbatical and went to the Christian Medical College School of Nursing in Vellore, South India, were she was interested in starting a baccalaureate program which was received well (Lobo, 1995). Dorothy Johnson has had an influence on nursing through her publications since the 1950s. Throughout her career, Johnson has stressed the importance of research-based knowledge about the effect of nursing care on clients. Johnson was an early proponent of nursing as a science as well as an art. She also believed nursing had a body of knowledge reflecting both the science and the art. From the beginning, Johnson (1959) proposed that the knowledge of the science of nursing necessary for effective nursing care included a synthesis of key concepts drawn from basic and applied sciences. In 1961, Johnson proposed that nursing care facilitated the client's maintenance of a state of equilibrium. Johnson proposed that clients were "stressed" by a stimulus of either an internal or external nature. These stressful stimuli created such disturbances, or "tensions," in the patient that a state of disequilibrium occurred. Johnson identified two areas that nursing care should be based in order to return the client to a state of equilibrium. First, by reducing stressful stimuli, and second, by supporting natural and adaptive processes. Johnson's behavioral system theory springs from Nightingales belief that nursing's goal is to help individuals prevent or recover from disease or injury. The "science and art" of nursing should focus on the patient as an individual and not on the specific disease entity. Johnson used the work of behavioral scientists in psychology, sociology, and ethnology to develop her theory. The model is patterned after a systems model; a system is defined as consisting of interrelated parts functioning together to form a whole (Conner et. al. 1994). Johnson states that a nurses should use the behavioral system as their knowledge base; comparable to the biological system that physicians use as their base of knowledge (Lobo, 1995). Theory The reason Johnson chose the behavioral system model is the idea that "all the patterned, repetitive, purposeful ways of behaving that characterize each person's life make up an organized and integrated whole, or a system" (other). Johnson states that by categorizing behaviors, they can be predicted and ordered. Johnson categorized all human behavior into seven subsystems (SSs): Attachment, Achievement, Aggressive, Dependence, Sexual, Ingestive, and Eliminative. Each subsystem is composed of a set of behavioral responses or tendencies that share a common goal. These responses are developed through experience and learning and are determined by numerous physical, biological, psychological, and social factors. Four assumptions are made about the structure and function of each SS. These four assumptions are the "structural elements" common to each of the seven SSs. The first assumption is "from the form the behavior takes and the consequences it achieves can be inferred what drive has been stimulated or what goal is being sought" (Johnson, 1980). The ultimate goal for each subsystem is expected to be the same for all individuals. The second assumption is that each individual has a "predisposition to act, with reference to the goal, in certain ways rather than in other ways"

Environmental policy and energy in the next 30 years Research Paper - 1

Environmental policy and energy in the next 30 years - Research Paper Example It is forecast that by 2025 natural gas will occupy the second position among all energy sources to be used worldwide. Much of the natural gas demand will be met by supplies from unconventional sources such as shale and rock formulations and it is estimated that its contribution will be almost 30 percent of total global production and the gas from shale and rock can meet world demand for next 250 years based on the current demand levels. China will witness the largest growth in gas consumption through 2040 amounting to nearly half of Asia pacific non-OECD consumption growth. Oil and natural gas together will meet 60 percent of the world energy needs. Demand for coal will reach at its pinnacle around 2025 and then will continue to decline due to shift toward non-polluting or lesser carbon emitting energies. Overall, oil, gas, and coal together will account for almost 80 percent of the energy needs of the world. Renewable sources of energy such as solar, wind and bio-fuels will registe r strong growth and likely to meet around 4 percent global energy demand by 2040. Hydropower and wind energy will show the fastest growth among the renewable energy sources – likely to register 8 percent a year growth. ... Nuclear energy is likely to grow at 2.2 percent a year worldwide and will have a checkered growth after Fukushima mishap in Japan (ExxonMobil, 2012). Below mentioned graph shows world energy consumption pattern between OECD and non-OECD countries. Source: http://www.eia.gov/forecasts/ieo/world.cfm In 2008, transportation sector consumed 27 percent of the total world energy demand and will grow at the rate of 1.4 percent until 2040. Major consumption or increase in demand will be from non-OECD countries as more and more people are adopting personal mode of transportation. Lesser population and economic growth in the OECD nations through 2040 will restrict the energy growth in the transportation sector at lowly 0.3 percent against likely growth of 2.6 percent per year in the non-OECD countries. Over the next 30 years, hybrid vehicles will become the mainstream vehicles for transportation needs and it is expected that by 2040, hybrid and other fuel efficient vehicles will constitute 50 percent of all light duty vehicles plying on the road. Commercial transportation energy needs through 2040 will also rise by 45 percent (ExxonMobil, 2012). Below mentioned chart shows likely consumption of energy in the transportation sector in OECD and non-OECD countries from 2008 through 2035. Source: http://www.eia.gov/forecasts/ieo/world.cfm Environmental Impact Burning of fossil fuels release huge amount of greenhouse gases in the atmosphere that lead to the greenhouse effect in which, gases such as carbon-dioxide, methane etc. absorb the heat and then release it back to the earth atmosphere (International energy agency, 2012). Due to higher consumption of fossil fuel (coal, oil, and gas) in next 30 years, the levels of global

Organizational Culture and Values - Essay Example This therefore requires expanded knowledge base which we cannot get anywhere else except from others who are more experienced than us. A nursing professional must be a strong team builder besides being an efficient problem-solver. Being affiliated to likeminded bodies will enable a nursing student or a nursing professional to develop these important skills (Nagelkerk, & Huber, 2006). Networking with other professional associations improves our management and leadership skills which are very vital in a nursing leader. Going beyond the borders of our nursing careers to affiliate ourselves with other bodies shows the strong focus and commitment that a nurse possess. Once we show such strong focus and commitment, being trusted will be a prerequisite to our career. As we gear towards our career advancement, we must strive to develop a strong network through joining professional associations aimed at inculcating positive traits required by employers. We should ensure that these affiliations are included in our resume for the potential employers to see. It is evident that most employers will be attracted to one who has diverse experience derived from personal affiliations and networks (Barnum, & Kerfoot, 1995). Medical organizations with a leader who has strong links and networks will definitely widen its roots. For us to join such organizations sooner or later, we must have strong personal affiliations and extensive networks for our career
