Differentiate a nation, a state, and a nation-state Essay

Differentiate a nation, a state, and a nation-state - Essay Example Ethnic nations originate from common races configured by similar traditions. The Japanese group of people is an ethnic nation of Yamato. Civic nation entails dissimilar population of different ethnic groups sharing a common belonging. The United States is an exemplary of civic nation since the country’s population is a diverse combination without common ancestry, similar language groups or dominant religion. A state refers to a given country with self-governing political units that hold elite jurisdiction over a given territory or region. The defining terms of a state include the population, given boundaries, and absolute sovereignty. The mandates of the said country maintains jurisdiction over the given population within a territory. â€Å"States or countries are independent political units that claim exclusive jurisdiction over defined territories and over all of the people and activities within them† (Dahlman & William 410). Different governments lack the power to exercise the absolute authority. As such, the state enhances or forces applicable patterns of a population’s activity to obey the rules provided in a certain political map. Cultural aspects define the organization of a said state in any portioning of a state. States exercise absolute sovereignty where a democratic space entails exclusive rights to the available population. â€Å"The idea that a state has the exclusive right to rule over a demarcated space and all the people and resources within it is known as sovereignty† (Dahlman & William 412). State features include transferred self-governing powers to a central government structure. The population of a state exhibit common identities with related origins. The nation state refers to a given state that rules a region with a population arising from united cultures. The concept of nation states embraces the initial development of nations that later attain protective states. The nation state focuses on dominate

Determinants of Plasma Retinol and Beta-Carotene Levels Statistics Project

Determinants of Plasma Retinol and Beta-Carotene Levels - Statistics Project Example The statistical analysis demonstrated that for this showed that sex was significant at the .000 level. Additionally, the research should that the strength of the connection was .045. Regarding the first hypotheses, the research showed conclusively that the null hypothesis could be rejected. As such, the research hypothesis -- Sex would not have the same impact on the occurrence of Plasma Retinol (ng/ml) levels as it does on Plasma beta-carotene (ng/ml) levels – was accepted. Regarding the second hypothesis, the research showed that the null hypothesis could not be rejected and that research hypothesis that a correlation exists between the occurrence of Plasma Retinol (ng/ml) and Plasma beta-carotene (ng/ml) in the body could be rejected. The first test that was carried out was a regression analysis. This regression analysis examined the correlation between sex and plasma Retinol (ng/ml) levels. As noted, this test demonstrated that there was a significant correlation between the two variables. The second test that was carried out was also a regression analysis. This test instead examined the connection between sex and plasma beta-carotene (ng/ml) in the body. This test demonstrated that there was not a significant connection between the variables. Finally, the third test that was carried out was an independent samples t-test. This test examined whether or not a correlation existed between plasma retinol (ng/ml) levels and Plasma beta-carotene (ng/ml). This research showed that a connection did not exist between these two

Part II Dream vs. Reality Get Rich Quick Schemes Essay

Part II Dream vs. Reality Get Rich Quick Schemes - Essay Example No matter what is said or done by advocates or opponents of gambling in all its various forms, it is an activity that is practiced, or tacitly endorsed, by a substantially majority of Americans." This statement, as have been proposals for legalization, has been ignored. These proposals have been rejected and, to data, casino gambling is only legal in a handful of states. Legal prohibitions against gambling have contributed to the emergence of an underground, illegal gambling sector which is not only flourishing but, continually expanding. Estimates place the total gambles illegally wagered over the past year at $48 billion. Apart from this meaning that states are losing an important, and major, source of revenues, there is a more disturbing implication. Within the parameters of an underground, black market gambling industry, the activity is unsupervised with the consequence being the participation of underage youth and the proliferation of no limits' gambling which both sustains gambling addictions and often leads to financial ruin. Through the legalization of gambling, implying the movement of an underground activity to the open, not only will states benefit from a wealthy source of revenue but the supervision of the activity by law enforcement will lead to stricter adherence to both age and ga

Tourism Essay Example | Topics and Well Written Essays - 500 words

Tourism - Essay Example The government should ensure that there is a maximum security for both domestic and international tourists. This will automatically increase the number of tourists visiting the region because they will feel safe. The government can also spread a good word about the destination by holding conferences both locally and internationally. B. The private sector should not be left behind in the promotion of tourism. This is because the benefits of booming tourist activities will not only benefit the government, but also the private sector. Therefore, through seminars and other forms of publications, the private sector can also play a vital role in the promotion of tourism. A. The whole process of promoting a region, though cumbersome, has a lot of reward. Advertising is one of the most effective ways of promoting a region as a tourist destination. Using both local and international mass media to advertise tourism packages is one of the most effect ways of promoting Kenyan tourism. A. The city of Mombasa has a wide variety activities and towns that will definitely satisfy the visiting people. This ranges from the fringed coastal beaches to the many old Swahili towns that served as residential areas for the early inhabitants of the coastal city. A. Tourism can also play a vital role to rid the city of its negatives, for example, the arrival of tourists from antidrug agencies such as the World Anti-Doping Agency (WADA) can promote the fight against drug abuse in Mombasa though sports and holding of educative conferences. B. Eco tourism is also another tourist activity that will impact positively, tourists visiting the fragile and relatively undisturbed areas and providing funds for ecological conservation will lead to economic development. B. The economy of the region will also improve as the money from outside will be spent in local hotels, restaurants and other businesses thereby leading to the rise in the economy and development of the region. A. To ensure

Critical Thinking - Basic Concepts of Quantitative Reasoning; Hypothesis Formulation - Research Paper Example An individual suffering from mild traumatic brain injury may lose perception for a few seconds or minutes or may remain conscious throughout. Other mild traumatic brain injury symptoms include confusion, headache, lightheadedness, blurred vision, dizziness, ringing in the ears, fatigue, bad taste in the mouth, sleep pattern changes, mood or behavioral changes, nausea, slurred speech, temporary loss of memory, attention, concentration or thinking capacity (Cifu et al, 2010; Murdoch & Theodoros, 2001). On average, more or less 2 million traumatic brain injuries transpire per year, either as isolated cases or by the side of other injuries. Common symptoms of moderate and severe traumatic brain injuries are abnormal social behavior, deficits in social judgment, frequent loss of attention, processing speed and executive functioning. Anyone with signs of traumatic brain injury ought to receive immediate medical attention; based on the fact that traumatic brain injury is a health risk. As a starter, medical personnel try to stabilize a person with traumatic brain injury and focus on preventing additional injury since little can be done to correct the initial brain injury resulting from the trauma; this is regarded as an initial treatment for traumatic brain injury. The primary concerns include ensuring proper oxygen supply, ensuring adequate blood flow, and maintaining normal blood pressure. Imaging tests help in diagnosing a traumatic brain injury patient (High, 2005). Patients with m ild to modest traumatic brain injury undergo skull and neck X-rays to check for bone fractures or spinal irregularities. Moderately to severely injured patients have to undergo rehabilitation depending on individual symptoms. Such therapy programs include speech/language therapy, occupational therapy, physiatry, psychology/psychiatry, and social support (Murdoch & Theodoros,

Read two essays, and which historian (Dan Carter or Bruce Schulman) Assignment

Read two essays, and which historian (Dan Carter or Bruce Schulman) does the best job of describing the origins of the New Right Why - Assignment Example Carter’s approach of depicting the origins of the New Right is from an event’s (politician’s race) perspective. However, his work neglected to explore the holistic nature of the New Right phenomenon and presented a one-sided argument -- that political movement alone spurred its resurgence. Carter’s work focused on Wallace’s contribution: â€Å"his attacks on the federal government have become the gospel of modern conservatism; his angry rhetoric, the foundation for the new ground rules of political warfare† (Hoffman, Blum, and Gjerde 485). According to his work, the resurgence of New Right started with â€Å"George Wallace’s racist populism, sharpened with Nixon and Agnew’s ‘law and order’ demagogy and triumphant with Reagan’s ‘tough on crime’ policies† (Lyons 28). Schulman’s work capitalized in his clear demographic story of the economic shifting towards the Sunbelt (a rightist territory) and establishment of supporting arguments about the strengthening of New Right. His arguments include the 1) stating of economic developments; 2) fostering of a less federal government; 3) posing the effects of the failure of North and Eastern unions like, they â€Å"had risen with the great industrial revolution in the heartland, and they were falling with it too† (Hoffman, Blum, and Gjerde 488); and emphasizing, not just political developments but socio-cultural developments. Schulman’s format worked well in presenting the emergence of New Right as a participating event in the â€Å"reconfiguration of twentieth-century American politics† (McGirr 273). Much of New Right activities took center stage in politics, yet its big picture lies in the industrial and commercial movements of the economy, and socio-cultural flow within the civilian spheres. Thus, it is appropriate to include not just a single perspective in presenting the New Right’s origins. Bruce Schulman’s work took heed of this topic’s nature and

The Theory of special relativity Essay Example for Free

The Theory of special relativity Essay Abstract: Prior to albert Einstein’s theory of special relativity there was always an idea about relativity. Through Galilean transformations, which worked perfectly with the newton’s laws of motion, people had formed a vague idea that all motion in this world is relative to something else. There came up the mysterious thing called aether — the medium through which light propagated. The belief in aether had caused a mess of things, in Einstein’s view, by introducing a medium that caused certain laws of physics to work differently depending on how the observer moved relative to the aether. In 1905, Albert Einstein published the theory of special relativity, which explains how to interpret motion between different inertial frames of reference — that is, places that are moving at constant speeds relative to each other. Einstein explained that when two objects are moving at a constant speed as the relative motion between the two objects, instead of appealing to the aether as an absolute frame of reference that defined what was going on. If you and your friend, say AA, are moving in different spaceships and want to compare your observations, all that matters is how fast you and AA are moving with respect to each other. Special relativity includes only the special case (hence the name) where the motion is uniform. The motion it explains is only if you’re traveling in a straight line at a constant speed. As soon as you accelerate or curve — or do anything that changes the nature of the motion in any way — special relativity ceases to apply. That’s where Einstein’s general theory of relativity comes in, because it can explain the general case of any sort of motion. Einstein’s theory was based on two key principles: * The principle of relativity: All objects move in a motion relative to one another. No motion except the speed of light is fixed. And the laws of physics don’t change, even for objects moving in inertial (constant speed) frames of reference. * The principle of the speed of light: The speed of light is the same for all observers, regardless of their motion relative to the light source. (Physicists write this speed using the symbol c.) Explaining theory of relativity and related concepts Classical Relativity (mechanics theory) Experiment: (Self thought and practically conducted) An everyday life situation when you are moving in a straight escalator. Standing on next to an escalator, I measured the speed of my mother, who was standing still on the straight escalator, using a Doppler’s radar. Speed measured by the radar= 3 km/h Then standing on the same escalator I measured the speed of my mother a few meters from me. Speed Measured by the radar= 0 km/h Explanation: Classical relativity states that all motion in this universe is relative to one another. Nothing is fixed. As measured by the radar the escalator and hence my stationary mother on it was moving at a speed of 3km/h. But when I measured the speed with myself on the escalator, the radar measured 0 km/h. This is because although my mother was still moving with the escalator’s speed her state of motion with respect to mine was stationary. Maxwell’s theory and the abolishment of aether theory Maxwell was a scientist who gave various laws with respect to electromagnetic radiation. He, through his equations, proposed that like all other EMRs even the speed of light could be calculated. James Clark Maxwell (1884) devised his famous equation, showing that the four basic equations of electromagnetism (one of which Maxwell invented so his equation would work, but it turned out to be correct), can be combined into a single wave equation. The speed of the wave is determined solely by a term involving known constants that appear in the original formulas. Thus, Maxwell showed that the speed of light was a constant and that its speed could be measured using electromagnetic experiments that were already in place to determine those constants. Nobody really believed that the speed was actually constant; they assumed that it was constant in some preferred reference frame, called the ether. But Michelson, together with Morley, attempting to measure the speed of the earth through the ether by measuring the speed of light in many different directions at once, found that the speed was constant in all directions. Nobody knew what to make of that in 1887. Then Lorentz gave his 3 sets of explanations to prove Maxwell’s observations. But all these three explanations were proved wrong by Einstein as he gave the theory of relativity. He believed light to be a constant at all times and abolished the idea of aether. His explanations involved the principles of Spacetime where he unified space and time to create a four-dimensional view of the universe with three dimensions of space and one dimension of time. Spacetime Einstein’s theory of special relativity created a fundamental link between space and time. The universe can be viewed as having three space dimensions — up/down, left/right, forward/backward — and one time dimension. This 4-dimensional space is referred to as the space-time continuum. If you move fast enough through space, the observations that you make about space and time differ somewhat from the observations of other people, who are moving at different speeds. According to Einstein, Space and time were a single unit and not absolute but relative. The movement in space affected the movement in time. The faster one moved through space the slower one goes through time. Thought experiment: (self-thought and data input based on other examples to explain concepts): Imagine a car moving at say a 100/s along the east direction and at zero speed toward the north direction. Then in one second it moves 100m towards east with no progress towards the north. Now say it moves north-east at the same speed. Because its speed is now diverted in two directions, it only moves 50 towards east and 50 m north. Same applies for space and time i.e. the faster you move through space the slower you pass through time. If you move at the speed of light then you make no progress in time and if you move at a speed that is greater than the speed of light, you can go back in time! Therefore, Einstein in order to measure distance between two objects chose to use a single entity called spacetime. Different observers would see different events in space in different ways. Some would see 2 events occurring at the same point in time but far apart in space, whereas other would see the same two events occur in very close to each other in space but far apart in time. Maxwell, using his 4 equations of electromagnetism proved that the speed of light was a constant. But his idea was rejected and everybody thought the speed of light was relative to a constant frame called aether. Also a concept called ether drift developed whereby light through all other media except aether would undergo a drift called ether drift opposing its speed. This was dependent on the velocity of the object. The more the velocity of the media, the less was supposed to be the speed of light through the media. Using this when Michelson, together with Morley, attempted to measure the speed of the earth through the ether by measuring the speed of light in many different directions at once, they found that the speed was constant in all directions and equal to the constant calculated by Maxwell. Now a question arose: how was this possible? The explanation to this was given by Einstein who abolished aether and said that the speed of light was a constant and through his theory of relativity demonstrated that how this was possible. To understand the fact that speed of light is a constant, we need to change our perspectives on distance and time from them being a relative quantity from a fixed quantity. This introduces to us two new concepts of time dilation and length contraction. Both time dilation and length contraction are immediate consequences of the Lorentz transformation Time Dilation Thought experiment: (taken from YouTube video on relativity) Consider this thought experiment. You and AA are in 2 different spaceships in space. Both of you are measuring trying to measure the speed of light. Your spaceship is stationary while your friend’s spaceship is moving at a constant speed, say 0.5c. To calculate time (which can be calculated by using any device that measures a certain event periodically) both of you are using 2 plates reflecting light against each other. (Look at the diagram below) Now in the (1) clock is the clock in the stationary clock i.e. the one on the stationary spaceship whereas the (2) clock is on the moving spaceship. Both clocks are identical. It is known that the speed of light is the same at all times. Therefore here in the stationary clock light moves up and down in a perpendicular distance the shortest distance. If the clock moves by 5 min every time the light touches the bottom plate then the clock would run at a certain speed and change appropriately. Now in case of the moving clock the light beam is travelling diagonally as the plates are constantly moving along with the spaceship in which they are present. Therefore the light takes a longer time to hit the bottom plate (as the speed of light is constant and light has to travel a longer path). Therefore the (2) clock runs slower than the (1) clock despite them being exactly identical. This phenomenon is known as time dilation, where the time on a ship moving very quickly appears to pass slower than on Earth. Length contraction The theory of special relativity revolutionized not just our understanding of time but our understanding of space too. I have already described the phenomenon of time dilation, whereby pairs of clocks in uniform relative motion each tick more slowly with respect to the other. A closely related effect is the phenomenon of length contraction (sometimes known as â€Å"Lorentz contraction†, â€Å"FitzGerald contraction† or even â€Å"Lorentz-FitzGerald contraction† after the physicists who predicted it on the basis of a crude forerunner of special relativity). Thought Experiment: (Taken from You tube Video But self-data input) Now in the spaceships example I have been using it can be said that if the two spaceships when at the same point i.e. when one is directly below the other and they release a beam of light and measure the speed of light after 12 seconds on the clock on the stationary ship which would be around 9 seconds on the clock aboard the moving ship if we calculate it using Lorentz’s transformations. Since the stationary ship is at rest in the space dimension therefore the rulers or any distance measuring instrument used would show that light travelled 12 light-second (the distance light travels in one second). The actual speed of light is 1light-second per second. Since the total time measured was 12 seconds. Therefore the speed would that would be calculated is 12 light second per second which is nothing but one light second per second. Since the second spaceship was moving at a speed half the speed of light it should calculate the distance of the light beam from the ship after 12 seconds on the clock aboard the stationary ship to be 6 light-second. But the actual distance measured by the rulers or any other measuring instrument onboard the moving ship will be 9 light-second. This is because of a phenomenon called length contraction. When an object moves at a very high speed i.e. a speed which is equal to or greater than 30% of c, then this length contraction can be seen up to some extent. Since the second spaceship was moving at 0.5*c, therefore the ship and all rulers or the measuring instruments used shrunk and the light beam was measured to be a distance of 9 light-second in 9 seconds, which is nothing but 1light-second per second. Conclusion As strange as it seems, this example (and many others) demonstrates that in Einstein’s theory of relativity, space and time are intimately linked together. If you apply Lorentz transformation equations, they work out so that the speed of light is perfectly consistent for both observers, i.e. one in motion at a constant speed and other stationary or at rest. This strange behavior of space and time is only evident when you’re traveling close to the speed of light, so no one had ever observed it before. Experiments carried out since Einstein’s discovery have confirmed that it’s true — time and space are perceived differently, in precisely the way Einstein described, for objects moving near the speed of light. The Consequence of Theory of Relativity: Unifying mass and energy (E=mc2) The most famous work of Einstein’s life also dates from 1905, when he applied the ideas of his relativity paper to come up with the equation E=mc2 that represents the relationship between mass (m) and energy (E). Einstein found that as an object approached the speed of light, c, the mass of the object increased. The object goes faster, but it also gets heavier. If it were actually able to move at c, the object’s mass and energy would both be infinite. A heavier object is harder to speed up, so it’s impossible to ever actually get the particle up to a speed of c. for example consider a proton accelerating towards the speed of light. As is moves closer to the speed of light its mass increases thus acting as a hindrance to the movement of the object. Until Einstein, the concepts of mass and energy were viewed as completely separate. He proved that the principles of conservation of mass and conservation of energy are part of the same larger, unified principle, and conservation of mass-energy. Matter can be turned into energy and energy can be turned into matter because a fundamental connection exists between the two types of substance. Thus if an object moves at a speed of light then it would have an infinite mass, negligible length and would make no progress in time.
