Funding For Special Education Program - 1544 Words

Funding for special education students is, and historically, has always been, a complicated issue. Most people believe the federal government funds special education in the United States. â€Å"Understanding Special Education Funding† (2009), states that, on average, most states estimate that the federal government provides less than 15% of the money needed to fund special education services. This, in turn, leaves local school systems responsible for funding the remaining portion of special education services. This paper examines the history of special education laws and funding, the wide variance of funding that exists from state to state, and the problems created by a lack of funding. Literature Review In a 2014 report from McCann, special education services were federally mandated for the first time in 1965 by the Education of Handicapped Children Act, and a two-year $3.5 million program was created to provide formula grants to states for funding education of special needs students. According to the website, www.understandingspecialeducation.com (2009), in 1975 Congress passed the Education for All Handicapped Children Act which guaranteed a â€Å"free and appropriate public education† (FAPE). This act was later modified and became the Individuals with Disabilities Education Act or IDEA. IDEA requires individual states to provide children with special education services as a condition of receiving federal funding for education.

Against Cloning Essay - 667 Words

Against Cloning As soon as you mention the word cloning, you are most likely to ignite a debate. This is because people are greatly divided on whether its good or bad. A way to reach a conclusion is to look at cloning from ethical, risk, and religious perspectives. The reality is, cloning is unethical, very risky, and irreligious. The arguments I will make will hopefully convince you that cloning is not good for the future. Cloning is very unethical. It would be violating the human rights in many ways. It would be violating of the freedom of beliefs and thoughts (Peter Flaherty, and D. Lynn Moore. Civics. McGraw-Hill Ryerson, 2000) Cloning also reduces human dignity. Humans can be sold as manufactured products. If we allow†¦show more content†¦My reply to that would be that it is not because curing someone is far more different that creating a new life and tampering with the way god created life. We should try to stick with God?s rules and his natural order instead of trying to make God?s rules. If we do interfere with this, we?ll interfere with natural evolution. (http://elibrary.bigchalk.com) If we interfere with natural evolution than who knows what other problems might occur? Cloning is a big step for the future, and everyone who defends cloning is too caught up with this new process of making new life, and not thinking about the consequences. Some of you don?t know that killer bees were cr eated by scientists. These scientists were too caught up with the bees, trying to make them better. But the bees escaped and turned out to be very dangerous. Killer bees have killed more than a 1000 people. (http://www.columba.edu) This is an example of the consequences of playing god. Cloning animals or humans would be very risky. Cloning is very unpredictable. Therefore no one can estimate exactly how risky cloning can be. We have already used a lot of animals in crazy experiments and none of them succeeded. Yes, even Dolly. Many of you think Dolly, the first animal to be cloned wasn?t really successful.

Design and Implementation of Automatic Traffic Light Controlled System Abstract Traffic signal controlled is playing more and more important roles in modern management and controls of urban traffic to reduce the accident and traffic jam in road. The gas lantern was turned with a lever at its base so that the appropriate light faced traffic. Unfortunately, it exploded on 2 January1869, in during the policeman who was operating it. The modern electric traffic light is an American invention. As early as 1912 in Salt Lake City, Utah, policeman Lester Wire invented the first red-green electric traffic lights. On5 August1914,theAmerican Traffic Signal Company installed a traffic signal system on the corner of East 105th Street and Euclid Avenue in Cleveland,Ohio. It had two colors, red and green, and abuzzer,based on the design of James Huge, to provide a warning for color changes. The design by James Hog allowed police and fire stations to control the signals in case of  emergency. The first four-way, three-color traffic light was created by police officer William PottsinDetroit, Michigan in 1920. In 1923, Garrett Morgan attended a traffic signal device. It was Morgans experience while driving along the streets of Cleveland that led to his invention of a traffic signal device. Ashville, Ohio claims to be the location of the oldest Working traffic light in the United States, used at an intersection of public roads until 1982 when it was moved to local museum. The first inter connected traffic signal system was installed inSaltLake City in 1917, with six connected inter sections controlled simultaneously from a manual switch. Automatic control of  inter connected traffic lights was introduced March 1922 in Houston, Texas. The first automatic experimental traffic lights in England were deployed inWolverhamptonin 1927. Ape-man chenpedestrian traffic signals have come to be seen as a nostalgic sign for the former German Democratic Republic. The color of the traffic lights representing stop and go are likely derived from those used to identify port (red) and starboard (green) in maritime rules governing right of way, where the vessel on the left must stop for the one crossing on the right. Figure: 4 Lanes Road. TECHNOLOGY Optics and lighting:- In the mid-1990s, cost-effective traffic light lamps using light-emitting diodes (LEDs) were developed; prior to this date traffic lights were designed usingincandescentorhalogenlight bulbs. Unlike the incandescent-based lamps, which use a single large bulb, the LED-based lamps consist of an array of LED elements, arranged in various patterns. When viewed from a distance, the array appears as a continuous light source. LED-based lamps (or lenses) have numerous advantages over in candescent lamps; among them are: †¢Much greater energy efficiency (can be solar-powered). †¢Much longer lifetime between replacements, measured in years rather than months. Part of the longer life time is due to the fact that some light is still displayed even if some of the LEDs in the array are dead. Brighter illumination with better contrast against direct sunlight, also called phantom light. †¢The ability to display multiple colors and patterns from the same lamp. Individual LED elements can be enabled or disabled and different color LEDs can be mixed in the same lamp †¢Much faster switching. †¢Instead of sudden burn-out like incandescent-based lights, LED start to g radually dim when they wear out, warning transportation maintenance departments well in advance as to when to change the light. Occasionally, particularly in green LED units, segments prone to failure will flicker rapidly beforehand. The operational expenses of LED-based signals are far lower than equivalent incandescent-based lights. As a result, most new traffic light deployments in the United States, Canada and elsewhere have been implemented using LED-based lamps; in addition many existing deployments of incandescent traffic lights are being replaced. In2006, Edmonton, Alberta, Canada completed a total refit to LED-based lamps in the cities over 12,000 Intersections and all pedestrian crosswalks. Many of the more exotic traffic signals discussed on this page would not be possible to construct without using LED technology. However, color-changing LEDs are in their infancy and may surpass the multi-color array technology. In some areas, LED-based signals have been fitted (or retrofitted) with special Fresnel lenses (Programmed Visibility or PV lenses) and/or diffusers to Limit the line of sight to a single lane. These signals typically have a projector-like visibility; and maintain an intentionally limited range of view. Because the LED lights don’t generate a significant amount of heat, heaters may be necessary in areas which receive snow, where snow can accumulate within the lens area and limit the visibility of the indications. Another new LED technology is the use of CLS (Central Light Source) optics. These comprise around 7 high-output LEDs (sometimes 1 watt) at the rear of the lens, with a diffuser to even outland enlarge the light. This gives a uniform appearance, more like traditional halogen or incandescent luminaries. Replacing halogen or incandescent reflector and bulb assemblies behind the lens with an LED array can give the same effect. This also has its benefits: minimal disruption, minimal work, minimal cost and the reduced need to replace the entire signal head (housing). THE PROJECT Design of Traffic-Control System: Through the project ‘Advanced Vehicles and Vehicle-Control Knowledge Centre’, the Hungarian National Office for Research and Technology supports the design of intelligent traffic-control systems. The main goal of the project is to interlace technological transfer by connecting universities, research centers and leading industrial partners. Automotive technologies are gaining ground in modern road traffic-control systems, since the number of road vehicles and passengers is rapidly growing. There is a perpetual need for safety-critical traffic automation, and traffic engineering makes the dynamic or static analysis and the synthesis of automotive vehicle technologies possible. The main goal of engineering is the planning and management of traffic systems. The project supports the development of reliable and optimal control structures for urban traffic and for motorway systems. The intelligent and cooperative set-up of actuation and its linkage to the central control system is vital for avoiding traffic jams and accidents. Moreover, environmental costs (e. g. pollution) can be decreased. The control architecture of systemic shown in Figure 1. | Figure 1: General traffic management and control structure. | | One aspect of the project aims at developing a traffic control algorithm for future technology. The design of the traffic control system can be evaluated in two steps – synthesis and analysis. Several models and multiple control strategies exist, and engineers must decide between them using a priori knowledge of the real system. Previously collected information can help to choose the appropriate model, parameters, measurement and control methodologies to create the optimal solution. In many cases, control-related variables are almost inaccessible for design unless estimation techniques are applied. In a situation like this, the approximation, computer-based estimation of the variables could be useful. Traffic simulations can be classified in several ways, including the division between microscopic, macroscopic and macroscopic, and between continuous and discrete time approaches. The methodologies of static and dynamic analysis of traffic systems are known. Several state variables, derived from the description of the dynamic system, can be used for operational and planning aspects. A newly emerged area is demand estimation through microscopic traffic modeling. The dynamic aspect of traffic simulation requires previously measured or estimated volumes of traffic. Since the measurement of certain variables in the dynamic description is rather costly, one tries to estimate them. For instance, the observation of constantly varying turning rates at a simple intersection is fairly costly. However, the number of turning vehicles could be applied to traffic light harmonization, or generally speaking to traffic light control. | Figure 2: Traffic jam in Dhaka City. | | Some time has passed since traffic issues were first addressed; in fact, traffic lights apparently existed a century ago. When they were first introduced, their purpose was to ensure the safety of people in the traffic, but as time has passed and traffic has become denser, flow-control issues have become important. Nowadays, control algorithms are extremely complicated, and take traffic-dependent light-control architectures into account. Nevertheless, complementary functions exist to augment the intelligence of such systems. The behavior of traffic is influenced by two main factors: the control inputs and the disturbances incurred. The control inputs are directly related to corresponding control devices such as traffic lights and variable message signs. The manipulation of disturbance Values is not possible, but in some cases they are measurable (e. g. demand), detectable (e. g. ncident) or predictable over a certain time horizon. The most challenging issues relate to automatic incident detection, the modeling of uncertainties, providing a solution that offers robustness under external disturbances, the use of variable message signs in order to avoid traffic jams, and finding an optimal itinerary. The development of an intelligent control structure ensures an optimal solution for all participan ts in the transportation and road traffic system. After the first year, the most significant result of the project is the structural analysis of the references. Several comparative studies have been elaborated to create a basis for further research on estimation and optimal light-control systems. Objective: The goal of this project is to given opportunity to practice designing and implementing sequential machine in this case, a traffic light controller. In this project, intergated circuit(IC’s) was chosen to design to traffic controller. The purpose of this project is to design an automatic, save and efficient traffic flow to assign the right way of the road. This project it was needed to design traffic control signals and implement to ensure whether this circuit is functioning or not. From that decrease a waiting time in road can reduce traffic jam in the road. The expected results of this project are three lanes can green other lanes are red at the same time. The result of this project can implemented with bulbs. (RED,YELLOW,GREEN) Components Required 1. Integrated Circuit 1. IC-1 (555) 2. IC-2 (CD4017) 1. Resistors 3. R1 (10K) 4. VR1 (100K) 2.

PCB LAWOUT: Figure: PCB Layout of Traffic Signal. The working Principle: This circuit is self explanatory by its name, and can be used to control traffic in public places, or to demonstrate traffic rules in traffic-parks. IC2, which is heart of the circuit, is a decade counter. In this counter for every pulse fed to pin-14, potential keeps shifting from D1 to D9 in cyclic order. IC1 is used as a pulse generator and generates pulses in regular configurable intervals. These intervals can be changed by varying VR1. The circuit is designed in such a way that out of nine pulses, relay RL1 remains triggered for 4 pulses, relay RL2 for 1 pulse and relay RL3 for remaining 4 pulses. Since D1-D4 provide current to T1, T1 is on whenever there is potential on any diode D1 to D4, which keeps relay RL1 triggered. Similarly other diodes are responsible for RL2 and RL3 triggering. Red, Yellow and Green lamps can be connected to the relays RL1, RL2 and RL3 respectively to complete your mini traffic light controller. Figure: 4-Lane Road Traffic Signal Planning. DESCRIPTION OF MAJOR COMPONENTS: 555 Timers –IC It is basically an 8–pin timer IC, which can produce precise time delay. It works on wide range of power supply voltage from 3V to 18V. The function of each pin of the IC is given below – * Pin–1: it is connected to ground (0V) terminal of power supply. * Pin–2: It starts up timing cycle, when its voltage is less than ? Vcc, the output of IC becomes high (1). * Pin–3: it is output pin which either source or sinks current up to 200mA. * Pin–4: it is reset pin. When it is + ve, IC works normally. However, when it is –ve, IC stops its working completely. * Pin–5: control voltage pin. It may not be used in normal working. * Pin–6: it is threshold pin. It finalizes the timing cycle of the IC, when its voltage is equal to or greater than ? Vcc, the output of IC becomes low (0). * Pin–7: it is discharge pin. It discharges external capacitor into itself. * Pin–8: it is connected to + ve terminal of battery, generally 3–18V. When the trigger is applied (i. e. switch is closed), the Trigger terminal (inserting terminal of lower comparator) is directly connected to the ground(0V). This toggles the output of lower comparator from LOW to HIGH. So the SET terminal of FLIPFLOP is at HIGH, toggling the Q to LOW. The output is Figure: 555timer output with high frequency Figure: 555timer output with high frequency 4017 Decade Counter: The count advances as the clock input becomes high (on the rising-edge). Each output Q0-Q9 goes high in turn as counting advances. For some functions (such as flash sequences) outputs may be combined using  diodes. The reset input should be low (0V) for normal operation (counting 0-9). When high it resets the count to zero (Q0 high). This can be done manually with a switch between reset and +Vs and a 10k resistor between reset and 0V. Counting to less than 9 is achieved by connecting the relevant output (Q0-Q9) to reset, for example to count 0,1,2,3 connect Q4 to reset. The disable input should be low (0V) for normal operation. When high it disables counting so that clock pulses are ignored and the count is kept constant. The ? 10 output is high for counts 0-4 and low for 5-9, so it provides an output at 1/10 of the clock frequency. It can be used to drive the clock input of another 4017 (to count the tens). Resistor: A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. The current through a resistor is in direct proportion to the voltage across the resistors terminals. Thus, the ratio of the voltage applied across a resistors terminals to the intensity of current through the circuit is called resistance. This relation is represented by Ohms law: Figure: Symbol of Resistror. Capacitor: A capacitor (originally known as condenser) is a passive two-terminal electrical component used to store energy in an electric field. The forms of practical capacitors vary widely, but all contain at least two electrical conductors separated by a dielectric (insulator); for example, one common construction consists of metal foils separated by a thin layer of insulating film. Capacitors are widely used as parts of electrical circuits in many common electrical devices. The capacitor is a reasonably general model for electric fields within electric circuits. An ideal capacitor is wholly characterized by a constant capacitance C, defined as the ratio of charge  ±Q on each conductor to the voltage V between them: Figure: Symbol of Capacitor. Transistor: A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistors terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuit Figure :Symbol of Transisitor. RELAY: A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits, repeating the signal coming in from one circuit and re-transmitting it to another. Relays were used extensively in telephone exchanges and early computers to perform logical operations.

The ultrasonic pest repellent device available on the market but a major drawback is that their power output is low and their effectiveness suffers. This electronic pest repellent generates powerful ultrasonic signals to repel pests. That’s reason we can protect our traffic light by this device. In summer season, pest is attracted by light at night. That’s reason lights are unable to through their full focus. That’s reason we add pest repellent with Traffic Light. Advantage of Traffic Light Controller: The following is from section 4B. 3 of the Ohio Manual of Uniform Traffic Control Devices: When properly used, traffic control signals are valuable devices for the control of vehicular and pedestrian traffic. They assign the right-of-way to the various traffic movements and thereby profoundly influence traffic flow. Traffic control signals that are properly designed, located, operated, and maintained will have one or more of the following advantages: A. They provid e for the orderly movement of traffic. B. They increase the traffic-handling capacity of the intersection if: 1. Proper physical layouts and control measures are used, and 2. The signal operational parameters are reviewed and updated (in needed) on a regular basis (as engineering judgment determines that significant traffic flow and/or land use changes have occurred) to maximize the ability of the traffic control signal to satisfy current traffic demands. C. They reduce the frequency and severity of certain types of crashes, especially right-angle collisions. D. They are coordinated to provide for continuous or nearly continuous movement of traffic at a definite speed along a given route under favorable conditions. E. They are used to interrupt heavy traffic at intervals to permit other traffic, vehicular or pedestrian, to cross. Traffic control signals are often considered a panacea for all traffic problems at intersections. This belief has led to traffic control signals being installed at many locations where they are not needed, adversely affecting the safety and efficiency of vehicular, bicycle, and pedestrian traffic. Traffic control signals, even when justified by traffic and roadway conditions, can be ill-designed, ineffectively placed, improperly operated, or poorly maintained. Improper or unjustified traffic control signals can result in one or more of the following disadvantages: A. Excessive delay; B. Excessive disobedience of the signal indications;   C.

Twelfth Night Essays (2028 words) - Cross-dressing In Literature

Twelfth Night Twelfth Night ?Twelfth Night is a comedy of light and shade. Its characters are not unreservedly happy and the events are not unreservedly humorous.? Discuss. As a comedy, Twelfth Night is obviously intending to not only entertain its audience but also point out problems in society. It is imperative to entire merit of the play not to be realistic but to allow for empathy. Therefor to have a comedy of complete lightheartedness there would be no balance and hence no avenue for audience interaction. Without light we would have no darkness and for this reason Shakespeare has had to incorporate tragedy in order for the comedy to have it's desired effect. The two in juxtaposition accentuate each other. The characters of Twelfth Night are neither bluntly humorous nor artlessly tragic. Twelfth Night like all Shakespearean comedies is largely about social concerns. The social messages in Twelfth Night are largely about, the need for a balance in life, that you should not judge on appearance as they can be deceptive and the importance of self awareness or the humor in lack of. Neither is artlessly or bluntly humorous, as this would detract from the greater issues he in attempting to convey. Humor instead is used in contrast to some pain to antithesis the comedy and accentuate the themes. The plot of Twelfth Night is comic it explores many social issues in it's comedy yet is also not unrestrained in it's humor. As a comedy Twelfth Night follows, many conventions as far as structure, the setting is in a far away ?romantic? land, situation, and events somewhat steer the plot however this is certainly not without art or subtleties. Shakespeare has carefully intertwined comedy and pain in both the main and the sub plots to highlight the comedy and explore the social themes. The audience is forced to suspend disbelief that such a coincidence could occur. The audience is transported from their ordinary mundane existence and is transported into a world of chance, non-existent penalties for practical jokes and the unmistakable harmony of events. It is this incongruity compared to everyday life that is humorous. However, this summer, frivolris setting is not completely free from conflict. There is however, some predominately ?lighter? characters that serve as comic relief from the more serious main plot and represent a certain ?type? of people in society. Sir Toby and Sir Andrew would have been marvelously enjoyed by Shakespearean audiences as they are today. Not a scene goes by involving these to where we can laugh and the slow wit of Sir Andrew and the awkward puns of Sir Toby. However, we find the names and foolish antics of these two rather amusing. It is with a certain hesitance that we laugh at the gullibility of Sir Toby, his disillusioned love for Olivia is rather somber and balances our opinion of him. This balances is representative of all the characters in Twelfth Night, they may be predominately comic yet they are never completely comic or completely serious. This has the effect on Twelfth Night as making it more true to life and therefor we as the audience can relate and understand the themes. Malvolio and Feste are typical examples of characters that are seen as comic, yet when looking beyond these superficialities we see a far more important role of their character in the play. Feste, his name and title as a ?fool? is careful balance of light and shade. He is arguably the most intelligent character in the play and it is evident at the end of the play that he is the most powerful, because he concludes the play. Feste is certainly a vital link between not only the main and sub plots but also as a conveyer of the action to the audience. It is ironic that such wit and wisdom are found in the ?fool.? Cesario refers to Feste as, ?This fellow's wise enough to play the fool: / And to do that well craves wit.? The obvious key to understanding the themes Shakespeare is conveying we must closely examine the characters, with which he communicates. Feste is not a character of low, blunt comedy, his merriment is truthful not scornful or artless. Act 1

Robert Sengstacke Abbott Biography

Robert Sengstacke Abbott Biography Abbot was born in Georgia on November 24, 1870. His parents, Thomas and Flora Abbott were both former slaves. Abbott’s father died when he was young, and his mother remarried John Sengstacke, a German immigrant.   Abbott attended Hampton Institute in 1892 where he studied printing as a trade. While attending Hampton, Abbott toured with the Hampton Quartet, a group similar to the Fisk Jubilee Singers. He graduated in 1896 and two years later, he graduated from Kent College of Law in Chicago. Following law school, Abbott made several attempts to establish himself as an attorney in Chicago. Due to racial discrimination, he was unable to practice law. Newspaper Publisher: The Chicago Defender In 1905, Abbott founded The Chicago Defender. With an investment of twenty-five cents, Abbott published the first edition of  The Chicago Defender  by using his landlord’s kitchen to print copies of the paper. The first edition of the newspaper was an actual collection of news clippings from other publications as well as Abbotts reporting.   By 1916,  The Chicago Defender’s  circulation was 50,000 and it was considered one of the best African-American newspapers in the United States. Within two years, the circulation had reached 125,000 and by the early 1920s, it was well over 200,000.   From the outset, Abbott employed yellow journalistic tactics-sensational headlines and dramatic news accounts of African-American communities. The paper’s tone was militant. Writers  referred to African-Americans, not as black or negro but as the race. Graphic images of lynchings, assaults and other acts of violence against African-Americans were published prominently in the paper. These images were not present to scare its readers, but rather, to shed light on lynchings and other acts of violence that African-Americans endured throughout the United States.  Through its coverage of the  Red Summer of 1919, the publication used these race riots to campaign for anti-lynching legislation. As an African-American news publisher, Abbott’s mission was not only to print news stories, he had a nine-point mission that included: American race prejudice must be destroyedThe opening up of all trade-unions to blacks as well as whites.Representation in the Presidents CabinetEngineers, firemen, and conductors on all American railroads, and all jobs in government.Representation in all departments of the police forces over the entire United StatesGovernment schools open to all American citizens in preference to foreignersMotormen and conductors on surface, elevated and motor bus lines throughout AmericaFederal legislation to abolish lynching.Full enfranchisement of all American citizens. Abbott was a supporter of The Great Migration and wanted southern African-Americans to escape the economic disadvantages and social injustice that plagued the South. Writers such as Walter White and Langston Hughes served as columnists; Gwendolyn Brooks published one of her earliest poems in the pages of the publication. The Chicago Defender and the Great Migration   In an effort to push the Great Migration forward, Abbott held an event on May 15, 1917, called the Great Northern Drive. The Chicago Defender  published train schedules and job listings in its advertising pages as well as editorials, cartoons, and news articles to persuade African-Americans to relocate to northern cities. As a result of Abbott’s depictions of the North, The Chicago Defender became known as â€Å"the greatest stimulus that the migration had.†Ã‚   Once African-Americans had reached northern cities, Abbott used the pages of the publication not only to show horrors of the South, but also the pleasantries of the North.

Sustainability and built environment Essay Example | Topics and Well Written Essays - 2000 words

Sustainability and built environment - Essay Example This human-caused earth warming is rising as one of the most important environmental, social, economic, and technological problem of the present century. (Todd, 1997, p. 99) The consequences of the problem are apparent in every part of the world (Johansen 2002, p. 01). The problem involves melting down of glaciers and ice caps at an accelerating rate higher than normal resulting in a dramatically increased rate of typhoons, tornados, and the hurricanes (Silverstein et al, 2003, p. 06). This has not only induced significant damage all around the world, moreover it has caused disturbance in the global ecosystem (Jabbra & Dwivedi, 1998, p. 26). Increase in earth climate, greater amount of acidity in oceans, accelerated rate of wildfires, heavy rain falls, are some other drastic results of the global warming (Oxlade 2006, p. 22). It is evident that global warming is not only an environmental threat, for instance, coastal areas are apt to remission, the rate of water consumption gets higher than the rate of water supply, and the land for agriculture turns into a waste by soil erosion (Houghton, 2004, p. 322) (Valsson, 2006, p. 116). Around the world, people are trying to find the solution to the problem of global warming and finding the techniques to mitigate its effect (Jones, 1997, p. 04). The best illustration of global collaboration against the disasters induced by global warming is that of the International Panel on Climatic Change. The organization consists of skilled and potent experts from the globe that keep an eye on climatic modeling and changes, and monitor every single alteration in the global ecosystem. IPCC is a perfect embodiment of global strives for a better and healthier mother earth (Williams, 2002, p. 15). The organization appreciates the part people around the world play in this regard, bring issues to the table, and attempt to solve the issues. Had there not be any IPCC we would not have any Kyoto Treaty or the Copenhagen Summits (Clarkson

Interracial Marriages Essay Example for Free

Interracial Marriages Essay In any marriage relationship, it is usual or rather natural to have some adjustments in its early stage. This is so because there is a high degree of expectations in both parties; and so, because these expectations are mostly â€Å"unrealistic,† to modify or adjust them are somewhat difficult to both sides. It is a fact that when two individuals come into a marriage union, they bring with them two different perspectives in almost all respects, and this is no different with interracial marriages. However, there are more at stake when racial backgrounds or ethnicity is the core issue, as studies reveal. Marriage and the fruit of the union – the family – is the basic unit of society and regarded as one of the most principal institutions of the social order. When marriages fail and families disintegrate, there is without a doubt a â€Å"ripple† effect on the community’s functioning in terms of that community’s solidity, and law and order. Although many facets of the relationship operate as components to the enjoyment and development of the marriage bond, the common and usual fundamental rationale for the union is intimacy. It is this vital ingredient that draws couples from different persuasions, race, or creed together despite the potential drawbacks and heartaches that will soon shake the very foundations of that union. This paper dwells on these potentialities in terms of the advantages and disadvantages of interracial marriages. The author believes that despite the difficulties and at times the impossibilities that complications beset interracial marriages, for as long as both parties or the individuals involved have explored beforehand the complexities, and settled for the facts and realities, their relationship is off to a better start. This paper then offers to describe and explain the polarities that entail in a marriage coming from two different ethnic or racial backgrounds. Definition demographics In US history, many things that speak of the American way of life are deeply affected and influenced on the issue of race and especially on cross-cultural marriages. Since its â€Å"pioneer† days, being attached with another not your own color, creed, or race is neither new, nor surprising. A study of endogamy’s other extreme, i. e. mixed marriage then and now is still quite of interest to many (Rosenfeld, 2007). To tackle the subject matter that this paper endeavors to explore, the author starts by defining the main concepts used throughout the study. Definition Marriage is defined as a â€Å"socially recognized and approved union between individuals† with the idea that both will commit themselves to a lifetime of togetherness in the hope that there will be stability and happiness that the couple will enjoy in their intimate relationship (Microsoft Encarta, 2005). Such relationship has legal, cultural, economic, moral, and psychological dimensions that may impinge on its eventual longevity and permanence. Miscegenation or â€Å"intermarriage between races†, according to Encarta, is defined as â€Å"marriage or cohabitation between people of different races† (2005). Demographics According to a study by Kara Joyner, assistant professor of policy analysis and management at Cornell and co-author of a study on interracial relationships in a recent issue of the American Sociological Review (Vol. 70:4), â€Å"Hispanics had the highest rate of interracial relationships: 45 percent of 18- to 19-year-olds and 33 percent of 24- to 25-year-olds were in interracial relationships in the early 2000s, compared with blacks (20 and 14 percent, respectively) and whites (16 and 12 percent, respectively† (Lang, 2005). Although Asians are comparatively the same with Hispanics in the aspects of interracial union in Joyner’s study, the ethnic group was not included due to lack of research yields when it comes to as when they likely get into their liaisons and when these end. However, in some studies, the case of Asians engaging in interracial marriage, demographics painted a different picture. Whereas in the case of Hispanics, Blacks, and Whites who intermarry, the surveys say that as they age, the tendency of these relationships’ potential to last dwindles, the Asians’ marriages tend to increase and last longer (Lang, 2005). The US Bureau of the Census points out that intermarriage is still â€Å"relatively uncommon† basing on a 2002 survey because only 2. 9 percent of all marriages come from interracial unions (Lang in Joyner study, 2005). Review of Literature Family Values Every home has its set of beliefs or tradition that they hold in high esteem. This is referred to as family values. Anything that the family believes is important comprises a family values system. This paper attempts to explain what family values are and how people uphold their beliefs and what makes them hold on to those beliefs in a highly individualistic country such as ours. Among the values an individual possesses, the most important I believe is that a person must regard most his/her values about family as the most significant. Many people don’t usually pause and contemplate what their values are. They may not know whether these values they already have are still practical or useful in a modern day world. Moreover, they do not think how their values fit in with their kind of milieu that they evolve in. (â€Å"Values: what are they? †2007). There are families that take time out though to impart to their children what had been passed on to them when they too were yet very young. The values may not be as strong as when were yet children because the person may have adapted to his world and adjusted his values that others may be accommodated. Through the years, a family value system may be a combination of what had been passed on to an individual and the values system of one’s friends or colleagues at work. Why are family values important? The primary reason is that what we hold as important affects how we use time, money and energy or how we interact with people. If a family believes the importance of education then parents try to save for the schooling of their children which includes books among others. Family values influence how we spend our resources and make decisions. Parents then need to communicate what their own family values are, why these are important and the specifics of what are most essential that the children must also adopt or follow. Children also need to respect others who have dissimilar value system as compared to their own. Most likely values will evolve but when parents lead the children and model these beliefs, their children will be able to learn and pass these on to the next generation (â€Å"Values: what are they? †2007). Social Clock The belief that there are descriptive and prescriptive age norms concerning adults during their developmental shift involves the concept of the social clock. The social clock hinges on its description of society’s expectations where time to get married and have children at the same time attaining more of life’s burdens. For example, the traditional or what has been considered as the perception of women who have not yet entered into matrimony as individuals who are negatively appraised during their middle adulthood stage in contrast to the young adults. Social clock has something to do with an expectation that a person must somehow behave or conduct him/herself according to established developmental milestones or else, risk the consequences that may happen because the individual has allowed it to slip through (Altenbernd, 2004).

Discrimination and Civil Rights in America Essays -- Civil Rights and

â€Å" Civil rights is the term that refers to the right of every person to equal access to society’s opportunities and public facilities.† Civil rights is used to imply that the state has a positive role in ensuring all citizens equal protection under law and equal opportunity to exercise the privileges of citizenship and to participate fully in life regardless of race, sex, religion, or other characters unrelated to the value of the individual. According to Webster’s Dictionary, the definition of civil rights is â€Å"the right s to personal liberty and to legal, economic, and social equality establish by amendments to the U.S. Constitution and by certain Congressional acts.† (Merriam-Webster) Civil rights have to with whether individual members of differing groups- racial, sexual, and the like- are treated equally by government and, in some areas, by private parties. Civil rights deal with issues of equality among the American citizens.   Ã‚  Ã‚  Ã‚  Ã‚  The concept that human beings having inalienable rights and liberties that cannot be violated by others or the state is linked to the history of democracy. It was first expressed by the philosophers of ancient Greece. In theory, Americans are equal in their rights, but in reality, they are not now equal, nor have they ever been. African Americans, women, Hispanic Americans, the disabled, Jews, American Indians, Catholics, and members of nearly every other minority group have been victims of discrimination in fact and in law.   Ã‚  Ã‚  Ã‚  Ã‚  The...

Computerized Scheduling System Essay

A computerized reservations and scheduling system is provided which alternately allows transportation consumers to select from pre-scheduled transportation services provided by transportation providers or to negotiate and contract with transportation providers who have available unscheduled transportation space. The system comprises a central computerized data base. Transportation providers and consumers alike access the computer via a plurality of terminal units. The central computerized data base comprises a â€Å"maybe† file for storing information regarding available unscheduled transportation space which may be offered by a provider for service if a suitable consumer demand exists and for storing information regarding unscheduled transportation space which is needed by consumers. The â€Å"maybe† file facilitates negotiating and contracting between the parties. Scheduling is the process of deciding how to commit resources between a variety of possible tasks. Time can be specified (scheduling a flight to leave at 8:00) or floating as part of a sequence of events. The word may also refer to: * I/O scheduling, the order in which I/O requests are submitted to a block device in Computer Operating Systems * Scheduling (broadcasting), the minute planning of the content of a radio or television broadcast channel * Scheduling algorithm * Scheduling (computing), the way various processes are assigned in multitasking and multiprocessing operating system design * Scheduling (production processes), the planning of the production or the operation * Schedule (workplace), ensuring that an organization has sufficient staffing levels at all times * Job scheduler, an enterprise software application in charge of unattended background executions. * Job Shop Scheduling, an optimization problem in computer science. http://en.wikipedia.org/wiki/Scheduling Scheduling is a key concept in computer multitasking, multiprocessing operating system and real-time operating system designs. Scheduling refers to the way processes are assigned to run on the available CPUs, since there are typically many more processes running than there are available CPUs. This assignment is carried out by softwares known as a scheduler and dispatcher. The scheduler is concerned mainly with: * Throughput – number of processes that complete their execution per time unit. * Latency, specifically: * Turnaround – total time between submission of a process and its completion. * Response time – amount of time it takes from when a request was submitted until the first response is produced. * Fairness – Equal CPU time to each process (or more generally appropriate times according to each process’ priority).

Mobile Money Transfer

CHAPTER TWO LITERATURE REVIEW 2.1 Mobile money transfer Mobile money transfer, also referred to as mobile money, mobile  payment, and mobile wallet generally refer to payment services operated under  financial regulations and performed from or via a  mobile device. Instead of paying with cash, cheque, or credit cards, a consumer can use a mobile phone to pay for a wide range of services and digital or hard goods. Although the concept of using non-coin-based currency systems has a long history,  it is only recently that the technology to support such systems has become widely available.Similarly, Julia s. cheney defined mobile financial services from her paper examination of mobile banking and mobile payments as follows â€Å"Mobile financial services is a term applied to a range of financial activities conducted using mobile devices, such as cellular phones or personal digital assistants. These activities fall into two broad categories: mobile banking and mobile payments. Mobile banking allows bank customers to check balances, monitor transactions, obtain other account information, transfer funds, locate branches or ATMs, and, sometimes, pay bills. In the United States, depository institutions' mobile banking platforms rely on one or a combination of the following three strategies: SMS text messaging, browser-based programs, or downloadable mobile-banking applications. The term mobile payments refers to payment transactions initiated or confirmed using a person's mobile cellular phone or personal digital assistant. These may be such things as making a purchase at the point of sale, sending money to a person or a business, or purchasing a product or service remotely. Mobile payments generally fall into two categories. Those made at the point of sale are called â€Å"proximity payments† and are typically initiated using NFC technology. Mobile â€Å"remote payments,† on the other hand, are not transmitted by NFC but rather require payments to be initiated and settled through the mobile cellular phone network in combination with an associated payment network. These payments may involve person-to-person, person-to-business, or business-to-business payments and rely on SMS text messaging, wireless Internet technology, or a downloaded application in order to execute the payment.Mobile payment is being adopted all over the world in different ways (wirelessintelligence.com) (erricson.com 2011). In 2008, the combined market for all types of mobile payments was projected to reach more than $600B globally by 2013 (juniper research 2013),  which would be double the figure as of February, 2011 (bonsoni.com 2011). The mobile payment market for goods and services, excluding contactless  near field communication  or NFC transactions and money transfers, is expected to exceed $300B globally by 2013 (juniper research 2013). In  developing countries  mobile payment solutions have been deployed as a means of extending financial services to the community known as the â€Å"unbanked† or â€Å"under banked,† which is estimated to be as much as 50% of the world's adult population, according to Financial Access' 2009 Report â€Å"Half the World is Unbanked† (financialAccess.org 2009). These payment networks are often used for  micropayments.  The use of mobile payments in developing countries has attracted public and private funding by organizations such as the  Bill & Melinda Gates Foundation,  United States Agency for International Development  and  Mercy Corps.Mobile financial services cover a â€Å"broad range of financial activities that Consumers engage in or access using their mobile phones† (Boyd and Jacob, 2007:6). They can be classified into three separate categories: mobile banking (m?banking), Mobile money transfer (m?money transfer), and mobile payments (m?payments) (GSMA, 2008a). M?banking is subsumed under the larger category of electronic banking.Electronic banking (e?banking) refers to â€Å"the provision of retail and small value banking products and services through electronic channels. These include deposit taking, lending, account management, the provision of financial advice, electronic bill payment and the provision of other electronic payment products and services such as electronic money† (Basel 1998:3). As a form of e?banking, m?banking is defined as:†Ã¢â‚¬ ¦financial services delivered via mobile networks and performed on a mobile phone. These services may or may not be defined as banking services by the regulator, depending on the legislation of the country in question, as well as on which services are offered.† (Bà ¥ngens and Sà ¶derberg 2008: 7).Porteous (2006) further explains that mobile banking can either be additive or transformational. For the former type, m?banking is considered an additional channel for existing clients to access banking services; in the transformational category, however, it targets clients who do not have bank accounts, aiming to include them into the formal banking system. (Bà ¥ngens and Sà ¶derberg 2008). Money, on the other hand, is a form of electronic money. Electronic money refers to â€Å"stored value or prepaid payment mechanisms for executing payments via point of sale terminals, direct transfers between two devices, or over the computer networks, such as the Internet. Stored value products include hardware or card based mechanisms (electronic purses or wallets), and software or network based cash (also called digital cash)† (Basel, 1998:3?4). M? money then refers to â€Å"services that connect consumers financially through mobile phones. Mobile money allows for any mobile phone subscriber – whether banked or unbanked – to deposit value into their mobile account, send value via a simple handset to another mobile subscriber, and allow the recipient to turn that value back into cash easily and cheaply† (GSMA, 2009:7). In this way, m?money can be used for both transfers and payments. In fact, m?money is generally used in m?payments and m?money transfers rather than for m?banking. As such, m?money does not earn interest compared to bank deposits. This ensures that all e?cash (of which m?money is one) dispensed and circulating corresponds to actual funds in the system. This helps the central banks track movements in money supply1 (Mapa, 2009). With this, m?money cannot be used for savings and cannot be lent by m?money service providers (Sec 5.C and D of Circular 649) (BSP 2009). However, whether these funds should not earn interest has been questioned by some, especially when the funds that are pooled to back?up the issued e?money can be deposited in a prudentially regulated institution or invested in â€Å"lower?risk† securities (Tarazi, 2009).Thus far, the use of m?money has primarily been transactional, such as payment of bills (including payment conversion of m?money to electronic loads), transfer of funds. In microfinance, for instance, the system has largely been utilized to transfer and pay loans.Mobile banking models:Lyman et.al. (2006) makes two distinctions of branchless banking: bank led Non?bank commercial actors. This was further expanded by Goswami & Raghavendran (2009) by breaking down mobile banking variants into 5 models based on how they partner up with telecommunication providers: (1) carriers going solo, (2) banks going solo, (3) exclusive bank and telecom partnership, (4) bank telecom open partnership, and (5) open federation model. These variations indicate that there is much innovation occurring with respect to delivering m?banking/m?money services. Although innovation is important, at some point, standardization would be needed to support interoperability that would enhance services among customers (GSMA, 2008a). In fact, of the five models mentioned, the open federation model is considered by Goswami & Raghavendran (2009) as the most flexible and dynamic since it allows for a partnership between all banks and telecom companies while sharing a common platform for m? banking. The platform then expands the coverage of mobile banking and gives the unbanked a freedom to choose with whom to maintain an account. The other implication of the variety of existing models is that it creates different regulatory arrangements depending on the nature of partnerships between telecommunication carriers and financial institutions. In the case of SMART Money in the Philippines, for instance, the banking regulations have complied with by its banking partner, whereas the telecommunications aspect is addressed by the telecommunications provider. A regulatory distinction however occurs once there is e?money issuance by a telecommunication company or non?bank entity through the telecommunications operator (Lyman, et al. 2006), as was the case with Globe Telecom's G?Cash. In both cases, they had to work with financial regulators on banking regulations it was not previously concerned with. Mobile phone payments is a popular and most preferable way of sending and receiving money in Africa since the vast majority of the continents' population are ruler dwellers or uneducated (Ayo, Ukpere, Oni, Ometo, & Akinsiko, 2012; Mangudla, 2012). The concept of mobile money transfer dates back to the history of telecommunication and banking industries. There are collaborations between the two industries for the facilitation of MMT service (Ayo et.al, 2012). M-PESA was the first MMT service in Africa, which was introduced by Safaricom of Kenya (A Vodafone partner) in 2007. M-PESA (M refers to mobile, and PESA refers money in Swahili language) can be accessed from the different outlets such as the headquarter, main branches of the company, or an authorized business outlet. Safaricom registered over 20, 000 consumers for M-PESA within the first month of introducing the service (Hughes & Lonie, 2007), and the number reached more than 15 million users of MMT in Kenya after five years of launching (Michaels, 2011). He contends that there are several factors behind the wide adoption and acceptance of this service by the users including rapid migration to cities for work, a significant unbanked number of the populace, the credibility of the service provider, and finally their commitment towards families in home villages. Therefore, as asserted by Hughes & Lonie, (2007), the M-PESA is primarily designed for the unbanked populace in Kenya. The MMT also was later introduced in several African countries such as Nigeria, South Africa, Tanzania, Ghana, Somalia among others. The success of these services in South Africa and Ghana were less than the Kenya's M-PESA success (Tobbin, 2010). MMT IN SOMALIA:MMT service in Somalia was first introduced by GOLIS , HORMUD and TELESOM telecommunication companies working with puntland, south central Somalia and Somaliland respectively. SAHAL and ZAAD money transfer was the first product; however, EVC, the hormud version of MMT, was banned by al-Shabab Group. The hormud company later introduced a more advanced service named EVC Plus. Other telecommunication service providers later offered similar products with different brands. For example, Nation link offer E-MAAL and somtel offers E-DAHAB services respectively. The lack of effective government in Somalia affected the necessities of the life and the telecommunication industry filled the governmental gap by introducing revolutionary technologies (Osman, 2012). The industry provides several services such landline, mobile phones, internet and mobile banking. The mobile banking or what we can refer to mobile money transfer is very popular in the most sophisticated and active people in Africa with regard to mobile phone payment (Osman, 2012).Many diverse factors contribute to the adoption and acceptance of these MMT services in Somalia. One major reason is that the banking systems in the country are very limited. In addition, there is much risk for caring cash since the country is still politically unstable and recovering from more than two decades of chaos and civil war (Mohamed, 2013). There are huge remittances sent by the Somali Diaspora back home to their families, friends, relatives, or business associates. There is also huge migration to the major cities because of economic crisis, famine, droughts, and job seeking. All these factors can contribute to the acceptance and usage of MMT service by the Somalis as they were behind its usage in other countries especially in Africa. There are limited empirical studies on the state of art of MMT adoption in the country. Sayid, Echchabi, and Abd. Aziz (2012) examined the mobile money acceptance in Somalia by drawing on the TAM model. Sayid et.al's (2012) study suggested that perceived usefulness and security positively affected the attitude towards mobile banking, whereas social influence and perceived usefulness significantly and positively influenced the intention to accept mobile money. Furthermore, their study suggested that perceived ease of use had positive effect on perceived usefulness of mobile money. Sayid et.al's (2012) sample size was very small (N=100) which is difficult to draw a statistical conclusion from it. In addition, this study looked at the MMT in a broader scope. However, their study provided useful insights about the factors influencing the acceptance and adoption of MMT in the country.The current study will examine the trends, challenge and future of mobile money transfer and banking in puntland. The study will focus sahal service as particular as there is no such in depth analysis in this service before. This service has 597,000 sahal service active subscribers which do mobile money services across puntland, similarly it has 86,000 active mobile payment subscribers which use sahal payment as their first choice paybills.The study will focus on these customers, the regulation and the mobile network operators to study the trends, challenges and future of this service.

Macintosh Retail Group Essays - Steve Jobs, Retail, Macintosh

Macintosh Retail Group Essays - Steve Jobs, Retail, Macintosh Macintosh Retail Group The Macintosh Retail Group A short summary The Macintosh Retail Group is a Dutch holding, that today competes in the sectors of clothing, living and automotives. It consists of the companies Superconfex (clothing), Kwantum, Tonton Tapis, Bartels Decor, GP Dcors, Klerkx Group (living), Halfords (automotive) and other smaller ones. Today, the group is active in several European countries, namely the Netherlands, Belgium, France and Germany. Some numbers for Macintosh 1990-1995 turnover in net profit in number millions of Dfl millions of Dfl of employees 1990 1,049.6 18.3 5,793 1991 1,070.1 30.5 5,730 1992 1,113.8 29.1 5,750 1993 912.1 51.3 3,616 1994 934.2 38.5 3,737 1995 999.8 22.5 4,136 In 1995 it made a profit of Dfl 22.5 million and employed 4.136 thousand workers. Looking on the results of 1994, we come to know that the group made 39% of its profit with fashion, 47% with living and 14% in the automotive sector, which is probably similar to 1995. During the history of the holding (it started with being a job creation program in 1932), the structure of the Macintosh Retail Group changed: Under the name of Cenfectie Ateliers Chas Macintosh N.V. it grew to the largest manufacturer of clothing in Europe in the 1950s and 1960s, which was done by acquire other companies. In the 1960s Macintosh started producing abroad, in order to remain competitive. This continued in the 1970s, at which time the production in Western Europe was nearly phased out because of the costs, especially to Belgium, Portugal and Tunisia. With creating a separate holding company and separate operation companies, the organizational structure was totally changed in 1977. But not even that step prevented the Group of making a negative operational profit of Dfl 19 millions in 1980. As a result of that, a recovery plan was developed by the management and a strategic planning process was introduced. It consists of changing production over to retailing, which is obviously a reason for the fact, that in 1990 about 90% of total turnover was realized in the retail sector. With acquisitions of companies of the sectors living and automotive in the last 15 years, the Macintosh Group continued enlarging. A climax of this development may be seen in the year 1993, in which the Group nearly stopped its complete production activities. It can be said, that throughout this process it evolved from a tailor to a retailer. The expectations of the management for the future are significantly to increase the number of the shops (334 in 1994), and consequently of the retail floor space (300.000 square metres in 1994). The Group tries to strengthen its market positions and to improve productivity. Strengthen its market positions should be reached with expansion through acquisitions on the international market, with concentrating in northwestern Europe. With doing this, Macintosh tries to establish and increase its position in the market sectors of clothing, living and automotive. Although the sector of clothes loses its importance within the Group, it is planned to develop this sector further during the next years.

A Narrative History of the French Revolution

A Narrative History of the French Revolution Interested in the French Revolution? Read our 101 but want more? Then try this, a narrative history of the French Revolution designed to give you a firm grounding in the subject: its all the whats and whens. Its also a perfect platform for readers who want to go on and study the much debated whys. The French Revolution is the threshold between an early, proto modern Europe and the modern age, ushering in a change so huge and all encompassing that the continent was remade by the forces (and often the armies) unleashed. It was truly a pleasure to write this narrative, as the complex characters (how did Robespierre go from wanting the death penalty banned to the architect of rule by terror and mass execution), and the tragic events (including a declaration designed to save a monarchy which actually crippled it) unfold into a fascinating whole. History of the French Revolution Pre-Revolutionary FranceFrances history of piecemeal territorial expansion produced a jigsaw of different laws, rights and boundaries which some felt were ripe for reform. Society was also divided - by tradition - into three estates: the clergy, the nobility and everyone else. The Crisis of the 1780s and the Causes of the French RevolutionWhile historians still debate the precise long term causes of the revolution, all are in agreement that a financial crisis in the 1780s provided the short term trigger for revolution. The Estates General and the Revolution of 1789The French Revolution began when the third estate deputies of the Estates General declared themselves a National Assembly and verbally seized sovereignty from the King while the citizens of Paris rebelled against royal control and stormed the Bastille in search of arms. Recreating France 1789 – 91Having seized control of France, the deputies of the National Assembly began reforming the nation, scrapping rights and p rivileges and drawing up a new constitution. The Republican Revolution 1792In 1792 a second revolution took place, as Jacobins and sansculottes forced the Assembly to replace itself with a National Convention which abolished the monarchy, declared France a republic and in 1793 executed the king. Purges and Revolt 1793In 1793 tensions in the revolution finally exploded, especially in rural areas where conscription and laws against priests caused open and armed rebellion against the domination of the revolution by Parisians. The Terror 1793 – 94Faced with crises on all fronts, the Committee of Public Safety embarked on a bloody policy of terror, executing their enemies – real and imagined – with no real trials in an attempt to save the revolution. Over 16,000 were executed and over 10,000 died in prison. Thermidor 1794 - 95In 1794 Robespierre and the other terrorists were overthrown, leading to a backlash against his supporters and the laws they had en-acted. A new constitution was drawn up. The Directory, t he Consulate and the End of Revolution 1795 - 1802From 1795 to 1802 coups and military power played an increasing role in the rule of France, until an ambitious and highly successful young General called Napoleon Bonaparte seized power and had himself elected Consul for Life in 1802. He would later declare himself Emperor, and a debate about whether he ended the French Revolution would outlast him (and continue to this day). He certainly mastered the forces the revolution unleashed and tied together opposed forces. But France would search for stability for several decades yet.

International Politics in Twentieth Century Essay

International Politics in Twentieth Century - Essay Example I will begin by giving a liberal account f the relationship between the economy, the state and power. Liberal idealism in international politics did not re-emerge, after the devastation f the Second World War, until the 1970s. Rapid advances in technology, the growth f organisations like the European Community, and the impact f events like the 1973 oil crisis pointed towards evidence f growing interdependence between states. At the same time liberal literature made significant inroads into the rigid inside/outside, domestic/international distinctions characteristic f realism, with the emergence f trans-national relations and world society. Modern interdependency theory uses free trade and the removal f barriers to commerce as prof to their claims. "The rise f regional economic integration in Europe was inspired by the belief that the likelihood f conflict between states would be reduced by creating a common interest in trade and economic collaboration amongst members f the same geographical region." European powers, instead f resolving their differences militarily, would cooperate within a commonly agreed economic and political framework for their mutual benefit. Eventually cooperation between states would increase and broaden as mutual advantages could be gained. Membership f the European Union would entail compliance with its rules, which itself would discourage the absolute pursuit f national interests and weaken state sovereignty. Liberal institutionalists such as Rosecrance argued that the "growth f economic interdependency had been matched by a corresponding decline in the value and importance f territorial conquest for states." In the modern world the benefits f trade and cooperation among states greatly exceed that f military competition and territorial control. Traditionally nation states regarded the acquisition f territory and land as the means to increasing national wealth. The state has transformed from being a 'military state' to a 'trading state'. Statesmen increasingly became aware that the accumulation f national wealth and development relied more heavily on macro-economic policies that increased the competitiveness f their economy compared to other states. Higher levels f efficiency, technology intensive modes f production and valuable human capital all give incentives for multi-national corporations and businesses to invest in the country. Neo-liberals point out that commercial relations between businesses and individuals have diminished the influence and power f the state. Although there is suspicion the role oil has played in the ongoing war in Iraq one cannot doubt the repercussions the war has had internationally. Britain and America have to some extent isolated themselves diplomatically from Europe (their closet allies) and the wider world. Nowadays due to the complications f economic interdependence it makes states less able to act aggressively because otherwise they face risking economic penalties imposed by other members f the international community.

Dance - an Art or Sport Term Paper Example | Topics and Well Written Essays - 1250 words

Dance - an Art or Sport - Term Paper Example Dancing expressions differ on whether can be used as an instrument of gesture and symbolism. As a result, some argue that they tend to be used for religious, ritual and ceremonial purposes. The expressions have differed in the way they define the cultural sequences of the body movement. The emotional expressions are also different as some explain that a person can dance without expressing emotions and that many groups do not just dance to music but rhythms in their minds. The expression does not inclusively compare dance to everyday movement, but they agree that it is repetitive (Ambrosio 58). Modern dance is a kind of theatrical dancing that is not as limited as classical ballet. In modern dance, movements express the feelings. Around the 1900s some American dancers started to rebel against the strict and confining style of Classical Ballet. Modern dance is very vivid, ever-changing and full of expression. Dancer’s like Alvin Ailey helped upgrade modern dance as we now see it. Art is basically one’s way of seeing them and expressing emotions. Because modern dance is without restriction deeper feelings and a stronger understanding is obtained. It is done easily due to this non-conforming way of dance. Urban dance or â€Å"street dance† describes any dance that has not come from formal beginnings like break dancing. This style is much improvised and can evolve without warning due to the individual. The beginnings of this style can be traced as far as West African culture. Dancing also plays an important role in culture. The rituals, dances, arts, music, and beliefs of a population are passed down from generation to generation. As previously discussed street dance is a modern take on old dance styles from older cultures. Some of the movements mimicked in modern times have come from Western Africa. Dances of celebration, acts of war, religious ceremony and been spread all over the world, but more so in the Caribbean and South American countries due to the old world slave trade. In Brazil, the African slaves that were shipped there also brought with them their culture of song and dance (Ambrosio 61).

Compare and contrast Gandhi and Plato on the issue of appearance and Essay

Compare and contrast Gandhi and Plato on the issue of appearance and reality - Essay Example pularly known as Mahatma Gandhi, and in India as the Father of the Nation was that ‘great soul’ in human form who was able to mobilize millions of people towards nonviolence through principles of nonviolence and truth; he rose to lead the Congress in 1920, during British Imperialism in India, and successfully brought an end to the British rule in India through his basic yet revolutionary principles and radical politics (Dalton, p.27). Both Plato and Gandhi, considered as highly learned super souls, possessed an ability to mobilize masses through their principles and values. Plato was the first one to differentiate between appearance and reality through his views of the world as a pale reflection of different forms as they appeared to the eye; he philosophized that the world is actually changing constantly, and all impressions, as seen, are mere forms (Gelb, 29). Plato explained his ideology of ‘world of forms,’ and their reality, through parable of prisoners in a cave; he pointed at the ‘reality’ of prisoners’ view that is restricted to their own shadows seen on the walls of the cave from the light behind them. If these prisoners are not exposed to outside world, they will tend to believe that the shadows that are visible are the forms of the world. When they are exposed to the outside world, which is the truth, they will not be able to accept it immediately and will have difficul ty in understanding and adjusting to the light and other objects of truth in the world. Through this explanation, Plato explained the relationship between knowledge and reality that is connected through wisdom. A true philosopher is the one who is in constant search of wisdom that will enable him to identify the goodness, truth, and beauty of life. Quite different in approach was Gandhi’s perception of appearance and reality, in other words conceptualization of metaphysics; were based on the issues that pervaded India for many centuries. Although Gandhi fought

Effect of Temperature on Shelf Stability of Soybean-corn Oil

Effect of Temperature on Shelf Stability of Soybean-corn Oil STUDY OF EFFECT OF TEMPERATURE ON SHELF STABILITY OF SOYBEAN-CORN OIL BLENDS. Atul Thakkar*, Jayshree Parikh** Abstract Soybean oil because of certain advantages is cultivated on large scale in recent years in India particularly in M.P, U.P, and part of Maharashtra. Soybean oil meal is rich in protein and the oil has ready outlet in vanaspati manufacture with the possibility, that it may be utilized as edible oil. The direct use of soybean oil for deep frying purpose has certain limitation as it contains significant amount of linolenic acid i.e. about 6.8 %. These polyunsaturated acids made the soybean oil unstable even under ambient conditions. Secondly the consumers do not have liking of the fishy flavor of the oil during deep-frying. Significant improvement in shelf life and thermal stability and flavor reduction can be achieved by lowering the linolenate content of soybean oil by blending in different proportions with corn oil. Corn oil widely used as an all purpose cooking oil and margarine because of the unique flavor it attributes and because it is more stable to oxidation than linolenate containing oil such soybean oil. Corn oil has milder taste and less expensive than most other types of vegetable oils. In present study to improve the stability and yet retain fluidity the soybean oil is blended with more stable corn oil thereby reducing linolenic acid content. The thermal stability for all the blends is studied by determining their Physico-chemical properties and fatty acid composition using standard methods. KEYWODS Soybean oil, corn oil, Thermal stability. INTRODUCTION Oils rich in Monosaturated fatty acid are gaining more importance these days due to their specific advantages over other oils. They are more stable towards oxidative changes over polyunsaturated fatty acid rich oils and hence prove to be better choice for frying or cooking application. Polyunsaturated fatty acid rich oils are more prone to oxidative changes, and hence promote oxidation in both food and non-food products, although important from health point of view. Thus while selecting oil or fat one has to consider both aspects that-oil should not be too much saturated and unsaturated as well. In fact as per latest guidelines of WHO/Japanese Heart Association the ideal ratio of SAFA: MUFA: PUFA should be 1:1.5:1.In order to derive maximum benefits from oil it is advised to consume a mixture of oils in order to maintain a balance between the fatty acids, and possible to keep cholesterol level in control. Now-a-days a number of blended oils are available in the market. For instance, blends of rice bran and sunflower oils. Soyabean oil is rich in protein but direct use of soybean oil has some limitation as it contains linolenic acid and it becomes unstable even under ambient conditions. To increase stability of soybean oil linolenic acid content must be reduce it can be done by changing fatty acid compositon this is possible by blending with more stable oils compare to soybean oil. In soybean oil linolenic acid is oxidized twice as quickly as linoleic acid and produces short chain aldehydes with flavor that are even stronger and less acceptable than those produced from linoleic acid, due to this odor of oil change. It can be used after one or two frying. It is the most saleable oil in india. Corn oil contains a significant amount of ubiquinone and high amounts of alpha and gamma tocopherols (vitamin E) that protect it from oxidative rancidity. It has good sensory qualities for use as salad and cooking oil. Corn oil is highly digestible and provides energy and Essential Fatty Acids (EFA). Linoleic acid is a dietary essential that is necessary for integrity of the skin, cell membranes, the immune system, and for synthesis of icosanoids. Icosanoids are necessary for reproductive, cardiovascular, renal and gastrointestinal functions and resistance to disease. Corn oil is highly effective food oil for lowering serum cholesterol. The use of corn oil to contribute to PUFA intake of 10% in the diet would be beneficial to heart health. It is rich in linoleic acid one of the three fatty acids . Corn oil beyond food and consumer product replacing petroleum in many industrial applications it is use as biofuel. Use of corn oil as a biodiesel is increases and for this purpose investment in cultivation of corn oil is increases not only in India but in Global states . It is used in pharmaceutical, cosmetic industries,paper, textiles, plastics, baked goods, candies, soups and mixes. It is also used as skin soother and softener. MATERIAL AND MEHOD Chemicals used A wide variety of chemicals were used in the experiments which are listed below. Acetic acid ,Acetone , Carbon tetrachloride,ethyl alcohol, HCl, Glacial acetic acid (All S.D.Fine Chemicals); Methanol, Chloroform, BF3-methanol solution (Qualigens); Hexane Heptane (HPLC grade, Qualigens); Wijs Solution (Merck Grade); isopropyl alcohol (China). Before using these solvents, their expiry was checked and these were stored properly. Reagens Used Sodium hydroxide Sodium thiosulphate Sodium sulphate Potassium iodide Sodium chloride,15% potassium iodide solution(15 gm of potassium iodide dissolve in 100 ml of water), potassium dichromate (All Qualigens). Before using these reagents their expiry was checked and was stored properly. Indicators Phenolphthalein (Qualigens) :-It was used by dissolving 1gm of phenolphthalein in alcohol. Starch (Qualigens):-Starch prepared by dissolving 1gm of soluble starch in 200ml distilled water and boil for few seconds. These indicators were prepared freshly as per the requirement of test. To observe proper colour changes during titration. Raw Material Soybean oil and Corn oil were purchased from market package of 1 liter. Before analysis, manufacturing and expiry date was checked properly. Before starting analysis, the colour and odor of these oils were checked. Methods Iodine value Iodine value is a measure of the degree of unsaturation in oil. It is constant for particular oil or fat. Iodine value is useful parameter in studying oxidative rancidity of oils since higher the unsaturation the greater the possibility of the oils to go rancid. This is the most important test to determine stability of oils. Peroxide value Rancidity is brought about by the action of air on the oil which is oxidative rancidity, where in, the fat takes up oxygen with the formation of peroxides. Peroxide value is the peroxide content in the oil.Procedure for determination for Peroxide value test was used from AOCS method. Free fatty acid value Free fatty acids are usually presents in oils along with the triglycerides. It increases during storage. It is keeping quality of oil; therefore the free fatty acid content generally increases on storage. This is most important test to find out quality of oils. This test performed according to the AOCS method. Fatty acid composition To find out fatty acid composition of oils gas chromatographic method is used because fatty acid evaluated in GC only it give prominent result. In this method oils first has to convert into methyl esters and then injected into the GC. Prepared sample seal in dry GC vial and kept in refrigerator before injection. Test performs as per the method of AOCS. The five major fatty acids in soybean oil are palmitate, stearate, oleate, linolenate, and linoleate. The fatty acids differ in the number of carbon and hydrogen atoms they contains, which causes differences in the nutritional value of each and their influence on the characteristics of food products. It show change in percentages when blend with other oils. All these tests were performed simultaneously. This study was followed by Thermal stability. In thermal stability study the sample was kept in oven which was set at 60oC. This stability analysis has been done continuously for seven days. For the thermal stability blends were prepared in the proportions given as in table 1. Pure oils were taken as reference. 250ml of sample taken in the 500 ml beakers, it was labeled properly. The beakers were not closed. Then the beakers placed in the preheated oven at 60oC for 6 hr. Then the samples were taken out, cooled at room temperature and analyzed for iodine value, free fatty acid content and peroxide value using AOCS methods. Then the samples were allowed to remain overnight at room temperature in a closed shelf. Next day the samples were again kept inside preheated oven for 6hr. followed by testing as above. Thermal stability testing was done continuously for seven days i.e.in all for 42 hours. Table 1: Ratio of blends and symbols used Table 2: Thermal stability: Iodine value. Table 3: Thermal stability: free fatty acid content. Table 4: Thermal stability: Peroxide value. Table 5: Results of Fatty acid composition (at 60Â °C for 42 hours) RESULT AND DISCUSSION The characteristics and fatty acid composition of oils used in the study are given in tables (from Table 2 to 5). All the oils were used fresh. During the storage studies at room temperature a small but steady rise in free fatty acid content and peroxide value and fall in iodine value was observed in all blends. In Shelf Stability (at room temperature) upto our 42 hours study Iodine value for pure soybean oil is ranging from (134.1 to 129.5), and Soybean oil,Corn oil composition ranging from (127.2 to 120.8), (120.7 to 115.8), (115.3 to 112.9), (108.1 to 104.9), (101.8 to 93.5) for pure corn oil (95.6 to 89.4). (Table 02, Figure 01). All these values indicate decrease in values of blends at high range compared to the pure oils. Decrease in iodine value may be due to the polymerization. Peroxide values in Shelf Stability (at room temperature) upto our 42 hours study for pure soybean oil is ranging from (3.1 to 7.2), and Soybean oil ,Corn oil composition Peroxide value ranging from (2.1 to 7.0), (1.9 to 6.9), (1.2 to 7.2), (0.9 to 7.5), (0.6 to 7.8) for pure corn oil (0.3 to 6.5) (Table 04, Figure 02). Free fatty acid content in Shelf Stability (at room temperature) upto our 42 hours study for pure soybean oil is ranging from (0.14 to 0.30), and Soybean oil ,Corn oil composition Free fatty acid value ranging from (0.15 to 0.34), (0.17 to 0.31), (0.18 to 0.30), (0.20 to 0.31), (0.21 to 0.32) for pure corn oil (0.25 to 0.33) (Table 03, Figure 03). The changes in these values may be due to oxidation which increases the free fatty acid content and peroxide value whereas decreases iodine value through marginally. The increase in peroxide value in the blend of soybean oil as the concentration of other oil increases indicates the increasing oxidative stability of blend as c ompare to other oil. The rate of decrease in peroxide value for soybean oil (Table 3) is very high as compared with corn oil.. This may be due to the presence of significant amount of linolenic acid in soybean oil, which is prone to oxidation. The rate of oxidation of all blends is slow as compared with pure soybean oil. When corn oil was blended with Soybean oil iodine value of soybean oil decreases and progressive changes observed in the peroxide value that is oxidative stability of Soybean oil increases. Corn oil has better shelf life than the soybean oil, Hence when soybean oil is blended with corn oil there is an increase in shelf life stability of soybean oil. Thus the present study of three blends certainly help to improve shelf life of soybean oil as compared to pure soybean oil. Fatty acid composition in Shelf Stability (at room temperature) linolenic acid content for pure soybean oil is (6.6), and Soybean oil ,Corn oil composition linolenic acid content (5.6), (5.3), (4.9), (3.5), (2.9) and for pure corn oil (0.7) (Table 5)..After 42 hours value of free Fatty acids are changed. It is indicated that, when soybean oil blended with corn oil there is decrease in value of linolenic acid content. After 42 hours also linolenic acid content show decrease comparing to initial stage of blending. The blend of Soybean oil with the corn oil shows good stability.
