The Anatomical Making Of The Human Body - 3697 Words

The anatomical making of the human body is one of complexity and preciseness. It is built to withstand foreign diseases, process biological data, and undergo a plethora of activities, which together compose one of the worlds most well-oiled and lubricated biological machines. The body is capable of maintaining itself and performing all of its countless activities thanks to the process of homeostasis. Homeostasis is the state of body equilibrium or stable internal environment of the body (Marieb, Hoehn, 2013, pg 8). Homeostasis is demonstrated in many ways; from sweating during an intense cardio workout to shivering in the chilly autumn air. The body also demonstrates homeostasis in the way that it reacts to stimulants that are ingested into the body. The focus of this experiment will be on the body’s reaction to a caffeinated beverage, over a period of time, which has been ingested into the body. The indicators of homeostasis that will be tested are: heart rate, blood pressu re and temperature. From the time that caffeine is ingested, the body is already absorbing it. Caffeine is absorbed in the mouth, throat, lining of the stomach, digestive track and intestines in the matter of about 99% of it being absorbed in forty-five minutes. â€Å"Caffeine is a stimulant of the central nervous system that occurs naturally in over sixty species of plants and is used in several foods, drinks and medications† (Mandal, 2014, para 1).

Paul’s Case Free Essays

In Willa Cather’s story â€Å"Paul’s Case,† the main character Paul is a troubled young man, who is seeking an escape from reality. Paul’s way of escaping his troubled life is through a day dream. For the most part Paul’s safe place is in New York City. We will write a custom essay sample on Paul’s Case or any similar topic only for you Order Now That is until Paul’s father comes looking for him. This is when Paul’s reality then takes form in his imaginary world. If Paul uses an imaginary escape world to get away from his troubled life, then why does it include him committing suicide? I have one reason to explain his suicide. Before, Paul supposedly enters his imaginary world, the story leaves off with Paul sitting in the cellar of his house. At this point in time, Paul starts to wonder if his father heard him entering. In the darkness of the cellar, Paul fears that his father may think Paul is a burglar, and shot him. (pg. 127) The though of death and Paul’s senseless running from a troubled life collide. In result creating Paul’s suicide, when his father comes looking for him. I believe Paul’s suicide serves as an epiphany. Paul’s epiphany relates to his struggling life, and how he has more to live for than just music. As a result of Paul’s epiphany, he begins to fade back into reality. As the audience, you are lead to believe that Paul was dreaming the whole time. The last sentence in the story â€Å"Paul dropped back into the immense design of things,† confirms the audience’s beliefs. (pg.133) Therefore I find it hard to believe that Paul ever actually traveled to New York. Due impart that Paul was a middle class kid from Pittsburg. Paul absolutely resented his lower and middle class upbringing. His resentment of his upbringing leads him to believe that New York is where the upper class lived. I find it hard to believe that he actually went to New York, because most of New York is slums. I find it hardly plausible or even possible that Paul actually lived most of the story, but rather that he imagined it all. The first problem that comes to mind when believing the story is the fact that Paul was able to get away with smoking cigarettes and drinking wine publicly. Paul was but a teenager with large sums of cash. How is it that Paul was able to live such a luxurious life for as long as he did, without being questioned about anything? The story â€Å"Paul’s Case,† was all about Paul seeking freedom from his personal life. Even though Paul was able to find some peace of mind, somehow his personal problems follow him into is dream land. Throughout Paul’s dream he encounters situations very similar to the ones he’s running from in reality. Nonetheless Paul can not escape his reality. How to cite Paul’s Case, Essay examples

Challenger Case Study free essay sample

On the fateful morning of January 26, 1988, the challenger shuttle broke up and burst into flames within 73 seconds of lift off. Many factors have to be considered when trying to figure out the cause of this disaster, and also how it could have been avoided. Poor communication between NASA managers, Thiokol managers, and Thiokol engineers played a major role in aiding this disaster. For a shuttle to be cleared for take off even when a lot of odds were against its successful liftoff shows that it was being run and monitored with a flawed system. This case study will be analyzed from the primary stakeholders perspective. It will go in depth into the cause of the disaster, both technical and ethical, how these problems can be fixed to prevent a reoccurrence, who the stakeholders are in the project and how they were affected by the disaster. The primary stakeholders include, but are not limited to, the astronauts, their families, the managers, the engineers at both NASA and Morton Thiokol, and the government. We will write a custom essay sample on Challenger Case Study or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page These entities are primary stakeholders because they were all directly involved with the mission in some way. The astronauts put their lives on the line; their families were also affected by the loss of a loved one in the disaster. Also, the managers and engineers at both NASA and Morton Thiokol are stakeholders because they were directly involved with the design, communications, and decision making prior to the launch. A lot of credibility was lost from both organizations after the disaster. Lastly, the government is a stakeholder because they invested heavily in the project There were various technical problems that mounted up to cause the challenger space shuttle disaster. The central technical problem was with the O-ring seal, which failed at lift off. Upon failure, pressurized hot gas was able to escape into the SRB attachment hardware and external fuel tank. Thereafter, the right-hand SRB’s aft attachment and the structural failure of the external tank were separated. Aerodynamic forces were then easily able to break up the orbiter. Lastly, the unavailability of an escape system didn’t give the astronauts the option of ejecting from the shuttle after it disintegrated. The managers at NASA knew years earlier about the flaws in the design of the SRB’s O-rings but never paid any attention to the issue. The technical problems could have been solved, and the crash averted is the O-rings had been redesigned as soon as the flaws were noticed. Also, an escape system should have been incorporated into the shuttle design just incase a mission has to be aborted after lift off. Lastly, it wouldn’t have hurt if a third O-ring was implemented. There were various ethical problems in this case which include the NASA managers failure to address the deficiencies in the SRB’s design, NASA managers non-chalant attitude about the engineers’ concerns, NASA managers hoarding of information from their superior managers and flaws in the decision making process at NASA The central ethical problem is the flawed decision making at NASA. This is the central ethical problem because the disaster was caused by the decision made to clear the shuttle for lift off even when there were technical concerns. This disaster could have been averted if engineers at Thiokol had communicated their concerns more effectively to their Managers, who in turn will communicate to the NASA managers on how the design specifications of the O-ring would not be able to accommodate take off at such a low temperature. Furthermore, information should have been passed on to upper level management at NASA as soon as the lower level managers learnt of the technical concerns, and maybe a decision would have been made to reschedule the lift off. The managers’ disregard for the engineers concerns shows their disregard for human life. The least they could have done was to notify the astronauts on the technical concerns of the Thiokol engineers. Improving communication between NASA managers, engineers, and superiors was the solution to the ethical problems. Lower level managers should have been willing to listen to the technical concerns of subordinate engineers. Lastly, safety and well-being should have been made a top priority instead of eagerness to launch. The IEEE code of ethics applies directly to the central ethical problems. The first principle states that one has â€Å"to accept responsibility in making decisions consistent with the safety, health and welfare of the public, and to disclose promptly factors that might endanger the public or the environment. † This principle was totally ignored by the managers at NASA. How can they be concerned about the welfare of the public when they aren’t even concerned of the welfare of their own? There was no reason why the space shuttle crew and higher-level management were not be notified of the technical concerns of the Thiokol engineers and the potential implications of the space shuttle take off. Also the IEEE code of ethics states that one has â€Å"to seek, accept, and offer honest criticism of technical work, to acknowledge and correct errors, and to credit properly the contributions of others. † In this case, the NASA managers ignored the technical expertise and concerns contributed by the Thiokol engineers. The managers didn’t even see the concerns as being critical enough for upper level management to be aware of them. By application of these principles, the concerns of the engineers would have been accepted, the astronauts and upper level management would have been kept up to speed on the development, shuttle lift-off would have been rescheduled, and lives would have been preserved. The central technical problem is related to the ethical problems in this case because these problems all contributed, one way or the other, to the disaster that occurred. The central technical problem could have been fixed though, if good engineering ethical standards were followed and the NASA space crew wasn’t pressured into a launch of doom. The secondary stakeholders in this case are the general public, other employees of the organizations involved, and the future astronauts. The public is considered a secondary stakeholder because their taxes are used to fund space shuttle projects just like this one. Other employees at NASA and Morton Thiokol who weren’t directly involved with the project are also secondary stakeholders because they are affiliated with the organizations involved. Lastly, school students are secondary stakeholders because they are the future astronauts, managers and decision makers. This mission serves as a learning experience for them. In conclusion, with all the concerns expressed prior to the lift off of the challenger on that fateful day, it should never have been allowed to lift off. In the future, better communication methods need to be implemented between NASA managers at all levels and the engineers they have contractual agreements with. Prompt and decisive actions should also be taken as soon as deficiencies are noticed in systems designs. Whistle blowing should be encouraged whenever an employee notices unethical methods being utilized by their peers or superiors. Also, major ethical decisions should never be made without getting the approval of upper level management. There is no reason why technical concerns relating to an event as important as a space shuttle launch shouldn’t be available to upper management. If better decisions had been made, the crew, which includes the schoolteacher, would still be alive today.

Synthesizing Carbonatotetraamminecobalt (III) nitrate: [Co(NH3)4CO3]NO3 The first attempt to dissolve the ammonium carbonate in 30. 0 mL of water failed because some chunks still remained. It was important to grind the ammonium carbonate down to a fine powder because the dissolution process took place very slowly and bigger chunks would not have dissolved. After all of the 10. 012 g of ammonium carbonate was dissolved, the liquid remained clear. The addition of 7. 56 g of cobalt nitrate to 15. 0 mL of water was very fluent and took on a color between dark purple and maroon. When the ammonium carbonate and cobalt nitrate solutions were added together, the new mixture was a blood red. After the mixture was stirred, however, it darkened and became nearly black. The 4.

While the solution, which was poured into a large crucible, was concentrated over a Bunsen burner, evaporation occurred very slowly. During evaporation, the solution bubbled a little, gas was evolved, and the dissolution of 2. 49 g of ammonium carbonate in the hot solution was visible due to tiny bubbles. After the evaporation was complete and the volume had dropped to 48 mL, the solution had the same appearance. However, after suction filtering the solution, the color became a lighter purple. After the cold water bath, it looked somewhat powdery on the bottom. Filtering a second time resulted in only a pink/purple powder which appeared somewhat crystalline. When the solid was mixed with a scupula during the 10 minute drying process, it looked a lot more like crystals. The final mass of the crystals was 3. 039 g. The balanced equation for the synthesis of carbonatotetraamminecobalt (III) nitrate is shown below as well as the calculations for determining percent yield. 2Co(NO3)2 + 6NH3 + 2(NH4)2CO3 + H2O2 2[Co(NH3)4CO3]NO3 + 2NH4NO3 + 2H2O Theoretical Yield: Density of NH3 (liquid) = . 628 g/ml Density of 30% H2O2 = 1. 11 g/ml Moles of NH3 = (30 ml)(. 628 g/ml)/(17. 031 g/mol) = 1. 20 mol Moles of H2O2 = (4. 0 ml)(1. 11 g/ml)/(34. 015 g/mol) = . 131 mol Moles of [Co(H2O)6](NO3)2 = . 025 mol Moles of (NH4)2CO3 = . 105 mol Limiting Reactant = [Co(H2O)6](NO3)2 (. 025 mol of [Co(H2O)6](NO3)2)(2 mol of [Co(NH3)4CO3]NO3 / 2 mol [Co(H2O)6](NO3)2) = .025 mol of [Co(NH3)4CO3]NO3 (. 025 mol of [Co(NH3)4CO3]NO3)(249. 066g) = 6. 22 g Percent Yield (Actual Yield/Theoretical Yield)(100) = (3. 039 g/6. 22 g)(100) = 48. 86 % Yield B. Measuring Absorbance Spectroscopy. Two distinct peaks of intensity were noticeable for the absorbance spectrum of the cobalt solution between 350 to 650 nm. Below are the calculations for determining the mass of crystals required to create a solution of the right concentration to produce a spectrum of absorbance at approximately 0. 6. A = ? lC 0. 6 = (100 M-1cm-1)(1 cm)(C mol/L) 0. 006 M = C mol/L mol = . 0006 .0006 mol = (mass)/(249. 037 g/mol) mass = 0. 149 g [Co(NH3)4CO3]NO3 The mass of [Co(NH3)4CO3]NO3 added to 100 mL of water was 0. 149 g. Initially, the crystals were dissolved in a beaker to ease stirring. After dissolving, the solution turned purple. The solution was poured into an Erlenmeyer flask and filled with more water to the line on the flask. Below are the calculations for determining the extinction coefficient at each lambda max. The graph for the absorption spectrum is attached. .579 = (? max)(1 cm)(. 006 M) ?max = 96. 5 .519 = (? max)(1 cm)(. 006 M) ?max = 86. 5 C. Measuring conductivity Below are the calculations for preparing a . 001 M solution of the cobalt complex in 100 mL of water. (. 001 M/1000 mL) = (. 0001 mol/100 mL) .0001 mol = (mass/249. 037 g/mol) mass = .025 g. Below are the calculations for finding k, the correction factor. k = literary value/actual value Literary value = 1384 i seimens Actual value of KCl = 1420 i seimens k = (1384/1420) = . 975 Below are the calculations for finding the conductance of the cobalt solution. Probe reading of cobalt solution = 90 i seimens [((1000)(90 i seimens))(. 975)/. 002M](1x10e-6) = 43. 88 i seimens D. Measuring Magnetic Susceptibility Average empty tube reading = -004 Mass of empty tube = . 884 g Mass of tube with crystals = 1. 022 g Height of chemical in capillary rod = 3. 25 cm. Average filled tube reading = -004 (diamagnetic) Temperature of the room = 18. 6 ? C No calculations required. E. Interpreting Infrared Spectrum [Co(NH3)4CO3]NO3 IR spectrum: spikes at frequencies(cm-1) of 280, 500, 830, 1290, 1380, 1600, and 3300. [Co(NH3)5Cl]Cl2 IR spectrum: spikes at frequencies(cm-1) of 830, 1290, 1550, 3200. NaNO3 IR spectrum: spikes at frequencies(cm-1) of 830 and 1380. Discussion A problem occurred during the conductivity measurements of the cobalt complex. The expected values for conductance were between 118 and 131, but the actual calculated value was 43. 88 microseimens. Clearly, the problem arose during the probe reading in the cobalt solution. It is possible that the probes reading was skewed because it made contact with the glass wall of the beaker. This problem would have definitely lowered the reading relative to what it should have been. The absorbance spectrum of the cobalt complex on the wavelength interval 350-650 nm displayed two distinct peaks, meaning that both ions of the coordination compound were separated. This suggests strongly that the coordination compound was indeed synthesized correctly. The absorption intensities at both lambda maxes were relatively close, around 0. 6. These absorption values were used in the Beers Law equation to solve for the molar absorbance, also called the extinction coefficient. Both molar absorbance values are fairly close to 100, but deviations of 4 and 14 imply that some impurities still remain in the compound, possibly left over from the evaporation process. The coordination compound characterization via magnetic susceptibility was rather simple data requiring no calculations. The reason for this is that the magnetic susceptibility reading of the crystal-filled glass tube was equal to the reading of the empty tube, and that both were negative values. Negative values signify that the coordination compound is diamagnetic, which means that no unpaired electrons are present. The reason for the pairing of electrons can be explained with crystal field splitting. When electrons are introduced to d-orbitals, a change in energy occurs. Electrons will move to orbitals with the lowest possible energy. The ideal behavior for electrons after occupying the dxy, dx2, and dyz orbitals is to pair with the electrons already in these same orbitals. This is true only if ? E, or the energy difference from these orbitals to the dx2-y2 and dz2 orbitals, is greater than the energy cost for pairing with electrons in the lower orbitals. In the case of the cobalt complex, the spin pairing energy is much less than ? E, causing the electrons to pair in the lower energy orbitals. This pairing makes the complex a low-spin complex, implying that it is in fact diamagnetic. The goal of the infrared spectroscopy analysis was to prove that the cobalt coordination compound which was created during this experiment was actually created instead of a different compound with similar properties and bonds. [Co(NH3)5Cl]Cl2 and NaNO3 were available to compare with the infrared spectrum of [Co(NH3)5CO3]NO3. Clearly, [Co(NH3)5CO3]NO3 cannot be the same compound as NaNO3 because they only share one infrared band. Both coordination compounds have a band at 3300 cm-1 which corresponds to a N-H stretch, one at 1600 cm-1 corresponding to N-H bending, one at 1300 cm-1 corresponding to N-H symmetric bending, and one at 830 cm-1 corresponding to N-H bending. The most important difference between these coordination compounds lies in the common spike of [Co(NH3)5CO3]NO3 and NaNO3 at 1380 cm-1. Because these two compounds share this spike while the Cl coordination compound does not, the 1380 cm-1 peak must represent an N-O bond, which is the most significant spike on the NaNO3 spectrum as would be expected. During the synthesis of carbonatotetraamminecobalt (III) nitrate, several factors could have contributed to the relatively low quantity of crystals formed in terms of the percent yield. After calculations, it was concluded that 6. 22 grams of crystals should have been produced. However, only 3. 039 grams was actually produced. One of these factors that may have contributed to the low percent error of 48. 86% is the short evaporation stage. Since time was a factor during the experiment, the solution may not have been given enough time to evaporate any impurities. While the final volume of the solution was verified to be 48 mL, under the designated 50 mL, more impurities could have evaporated. If the solution had sat above a Bunsen burner for a greater length of time, it would have undoubtedly become more concentrated. Another factor which possibly contributed to a low percent yield is measurement errors. Although a good level of confidence can be felt about whether or not the right amounts were added, there is always room for error. A simple miscalculation or slight deviation in a measurement could have thrown off the remainder of the synthesis. Furthermore, a very obvious source of error can be found regarding the filtering system. The crystal product is quite soluble in water for the fact that its ions can be easily separated. For this reason, ice cold water was used whenever contact had to be made with the crystals; the low temperature of the water prevents the dissolution of the crystals to some extent. In the filter, some of the crystals could have dissolved and fallen through, which would have resulted in a poor percent yield. In general, this experiment ran very smoothly and achieved its purpose of providing detailed information regarding the properties and synthesis processes of a transition metal coordination compound. To improve the results of percent yield and perhaps to improve the results in many areas of characterization, the evaporation stage should be lengthened to facilitate the removal of remaining impurities.

Consumerism, Environmentalism, and Marketing Essays

Consumerism, Environmentalism, and Marketing Essays Consumerism, Environmentalism, and Marketing Paper Consumerism, Environmentalism, and Marketing Paper In economics, consumerism is the free choice of consumers, which dictates economic structure of society. Consumerism is an international phenomenon. Consumerism also includes the promotion of consumer rights and protection. Changing fashion and planned obsolescence benefit the producer. Twentieth century consumerism shifted from values of community, spirituality, and integrity to ore competition, materialism, and disconnection. Upper class consumers are desired targets for marketing campaigns (Miller, 1991). A consumer may derive a great deal of satisfaction from purchasing something that improves their social status. Generally, consumers seek to emulate those who are above them in the social hierarchy. Environmentalism is a social movement concerned with conservation and improvement of the environment (Luke, 1997). Environmentalism is associated with the color green from dark green to light and bright green. Environmentalism seeks to influence politicians through lobbying, activism, and education. The environment movement, ecology, health, and human rights, advocates for management of natural resources and changes in public policy. Environmentalists try to give the natural world a stronger voice in human consciousness. In the 20th century, environmentalists gained popularity and recognition. Efforts to save wildlife and the National Park Seen. ice founded by President Woodrow Wilson in 1916 were in response to environmentalists. In 1962, Houghton Muffin published Silent Spring by biologist Rachel Carson who eased public concern about EDT and other pesticides that may cause cancer and were a threat to wildlife, especially birds. Groups like Greenback and Friends of the Earth focused on air pollution, oil spills, and water contamination. Free market environmentalism values health and sustainability of the environment. Environmental preservation, chiefly in the United States, concerns prevention of damage to ecosystems caused by human activities, such as logging, mining, hunting, and fishing, replacing them with tourism and recreation. Natural wildlife preserves are advertised as a place to relax and learn about the carrying capacity of the delicate ecosystem. Pocket is minutes from the Ocean City beach resort, the Assuaged National Seashore Wildlife Refuge, and Wallops Island, home of the National Aeronautic and Space Administration, and the National Oceanic and Atmospheric Administration.

3 Ways to Double Up When Converting Passive Constructions to Active Ones

3 Ways to Double Up When Converting Passive Constructions to Active Ones 3 Ways to Double Up When Converting Passive Constructions to Active Ones 3 Ways to Double Up When Converting Passive Constructions to Active Ones By Mark Nichol Revising sentences so that they’re more active isn’t mandatory, but strive to make most of your passively constructed sentences more dynamic- and while you’re at it, don’t overlook opportunities to give a sentence more than one burst of energy. 1. Now that you have the business activities and conflicting activities defined, the associated privileges can be assigned to those activities. This sentence is easily rendered more active by repurposing the adjective defined as a verb and fortifying the bland verb have with it: â€Å"Now that you have defined the business activities and conflicting activities, the associated privileges can be assigned to those activities.† Even better, make the sentence imperative and therefore more forceful by beginning the main clause with the verb rather than the noun phrase: â€Å"Now that you have defined the business activities and conflicting activities, assign the associated privileges to those activities.† 2. There will still need to be thought given to understanding how conflicts of interest are identified and managed. Avoid beginning a sentence with a vague expletive; start with a noun: â€Å"Thought will still need to be given to understanding how conflicts of interest are identified and managed.† Better yet, enable the more active basic form of the verb give by employing the key noun at the outset: â€Å"Management will still need to give thought to understanding how conflicts of interest are identified and managed,† and explicitly stating that management itself identifies and manages conflicts of interests, rather than implying some vague actor, will strengthen the sentence even more: â€Å"Management will still need to give thought to understanding how it identifies and manages conflicts of interest.† 3. These have been in place for about ten years, with compliance actively monitored through annual assessments undertaken by a qualified assessor.

What Is The Most Important Thing In Socialism Assignment

What Is The Most Important Thing In Socialism - Assignment Example Socialism also at the time revolutionary in nature as most of the socialist society tends to be dynamic. In revolutionary socialism, a socialist society comes up with new ways of doing things and improving on the existing ones while ensuring that the common good stands. In modern society, there is false consciousness about socialism as many societies use democracy to imply socialism (Steger, 80). In socialism, there is the idea of common ownership and the issue of sharing properties, but in democracy, capitalism sets in and it is only a few influential personalities who own properties. The influential people normally sway the masses and at the end of the day, it looks like the common good are prevailing. In reality, the few individuals get their way. This is the false consciousness that modern society holds on socialism.Politically, one of the leading fathers of socialism is Karl Marx. In his argument, Karl Marx believed that capitalism was responsible for the exploitation of the var ious workers and citizens around the world. He was of the idea that a social revolution was the way out when it comes to dealing with capitalism. Marx saw the class system in society as a factor leading to alienation and hindering the freedom of citizens (Marx and Friedrich 89). He believed that a social-political system where the political power rested with the community and private ownership of properties existed was all that a society needed to realize the freedom from capitalism. However, this argument of a revolution does not hold always as some agents and parties normally take advantage and in the presence of championing the common good revolt for their own personal interests (Nicholls 79). Therefore, in as much as revolutionary socialism is effective in political liberation, caution must be taken when implementing it. The two major stages according to Marx is where the class is retained, but then the goods are commonly owned and the second stage is where the class is fully ab olished and the state becomes unnecessary leading to a utopian society. This may lead to anarchy and lawlessness in the end (Kropotkin et al. 102).

Adapting to a new enviroment Essay Example | Topics and Well Written Essays - 250 words

Adapting to a new enviroment - Essay Example Being in the prosperous middle east of Asia, Kuwait is not a poor country. In cities there is good infrastructure and facilities and living there is not living like nomads in some backward desert. But when I moved to Irvine, I came to know that although I was not living like a nomad in a desert but still it was a very different place. I was used to that place and it seemed very natural and comfortable and I never had to do anything special to adjust in my peers. I just moved along naturally. Moving to America was another thing. I had to adjust in a new environment, the weather was alien, and the people were not the people that I had been living with. The first thing that I felt badly in a need of when I moved to America was friends. And making friends in a different country with people who have a different culture is not easy. And the greatest barrier in that is language. It is very difficult to be friends with people who do not talk like you. But slowly I started overcoming my shyness and found out that the only way to do it is to break ice and put a step forward. Practically adjusting in a very new environment and routine was a challenging task. Studying here was not like studying back in Kuwait. I had to adjust a lot while managing my studies with the new methods and schemes of studies. Also belonging to a different culture we used to have different pastimes and interests but here I had to slightly adjust my taste in various things to live with the new people and my new friends. I had to adjust with new places, routes and markets that were unfamiliar and it took time to completely settle here comfortably. Apart from the practical aspects mentioned above, what helped me most in adapting to this new place and environment was my flexibility. Adjustment in a new culture also requires a lot of compromise and flexibility. You

Automated Classroom Monitoring System Essay Example for Free

Automated Classroom Monitoring System Essay Every academic institution aims outstanding scholastic performance of each and every student enrolled. Not only the schools but also the parents of these students hope to see their sons and daughters to excel in school with flying colors. In order to achieve so, students must attend their classes regularly so that they will be given the utmost standard learning experience. Class takes it to another level, an automated, secured and efficient attendance checking system. There are certain reasons why schools are encouraged to apply this kind of technology. Teachers nowadays are having problems in taking daily attendance of the students, sometimes they forget to take it or they will just simply give the class a blank paper to let them write their names and sign so it will serve their attendance and then later on who knows if that paper will be misplaced. This system will replace the obsolete swipe card system with finger authentication technology that is more reliable and accurate. With this technology, attendance will be recorded faster to the database with just a touch of the thumb. ____________________ is an automated system located on every classroom, equipped with biometric technology and automated SMS software, interfaced with a computer server where the database is then saved. Statement of the Problem School instructors have responsibilities inside the classroom towards the students. It is their duty to ensure all the students enrolled in that subject must benefit the lesson that the class is taking up at the moment. But sometimes teachers forgot to take class attendance or misplaced them. That’s why parents can not be guaranteed that the students are inside the school premises because the teachers do not have the data that will support the situation. The main objective of conducting this design is to improve the automated attendance monitoring system in academic institutions and to help the parents of the students to be able to monitor their child whether he/she attended school or has been cutting classes. Hypothesis of the Study 1. Ensures that the daily attendance of the class will be taken and a soft copy will be saved on a database and print a hard copy for the instructor’s documentation. 2. To limit the students from loitering in hallways during class hours. 3. Minimize the tardiness of students in attending classes. 4. Avoid altering school documents that are accessible only by the instructor in authority. 5. Provides parents the chance to monitor the attendance of students. 6. Enables the instructor to inform students if he/she is not going to be able to come in class on time or will be absent. 7. To replace the obsolete and inefficient swipe card technology with the finger print authentication biometric technology. 8. Saves class time for discussion instead of the traditional roll-call of the names of each student. Theoretical framework of the study This research is stimulated for the development of the school’s attendance monitoring system, provided with the biometrics technology and automated system. This will help the school authorities to have a permanent and more secured database management in attendance monitoring. A study from Teleron 2000 â€Å"Data Acquisition on Class Hour Attendance of the Faculty in Southwestern University† features the same concept as ____________, but his study is focusing only on school staff. Teleron used Barcodes on the staff’s ID that contains the data and the Bar code reader on the other hand reads the bar codes as the staff swipes the IDs. He recommends the use of biometric technology and further enhancement of his study, which convinced the researchers to push through to work with _______________________. Biometric devices nowadays are preferable than other authentication technologies such as barcodes and magnetic stripe scanners. This kind of technology is difficult to alter or tampered because it needs a unique pattern for authentication. Amazingly, human finger possesses unique ridges and valleys that differ from one human being from another, even identical twins. The first advantage of using this new technology is the uniqueness and it is also the main characteristic which allows biometrics technology to become more and more important in our lives. With uniqueness of biometrics technology, each individuals identification will be single most effective identification for that user. A chance of two users having the same identification in the biometrics security technology system is nearly zero (Tistarelli, 2009). Significance of the Study People who will be benefited by this project design favor those in: TEACHERS This innovated technology will be able to help the teachers to mark and update student class attendance quickly. He/She can easily print hard copies of the attendance in case of necessity. It will lessen wasted time on roll-calls and teacher can immediately proceed into his/her lecture. STUDENTS Our design will be mostly be benefited by the students. PARENTS/GUARDIANS The parents will easily track their sons and daughters’ attendance by simply sending the right keyword to the ____________ through Short Message Service (SMS). They will know at once when the students are really attending the class or cutting classes when the system will reply after they sent the SMS. They can also ask for a hard copy of the attendance, for example: they want the record for the whole month of January; the teacher will look up on the records of that particular student and then print it right away. Scope and Delimitation This design project aims to help the faculty and the entire student body of this institution to promote secure monitoring of the students’ attendance during class hours, and that parents will also be given the chance to know the student’s status first hand with just an SMS away. Researchers designed the biometric device to be located on every classroom only. Since the device is powered by electricity, a sudden loss of power will interrupt the whole system if there is an on-going entry, where it will take a few minutes for the generator to supply electricity temporarily for the system to resume. SMS feature of the system is limited only to the parent’s cellular number given to the administration encoded on the database. Other cellular numbers unknown to the database or not recorded can not be entertained by the system. Incase parents want to add or change phone numbers for the system; they have to submit a new form to the administration for approval and re-entry of data. Definition of Terms Listed below are the terminologies and the conceptual meaning used in the study. BIOMETRICS It is the measurement and analysis of unique physical or behavioral characteristics (as fingerprint or voice patterns) especially as a means of verifying personal identity. (http://www.merriam-webster.com/dictionary/biometrics). FINGERPRINT SCANNER Fingerprint scanning essentially provides an identification of a person based on the acquisition and recognition of those unique patterns and ridges in a fingerprint. The actual fingerprint identification process will change slightly between products and systems. The basis of identification, however, is nearly the same. Standard systems are comprised of a sensor for scanning a fingerprint and a processor which stores the fingerprint database and software which compares and matches the fingerprint to the predefined database. Within the database, a fingerprint is usually matched to a reference number, or PIN number which is then matched to a persons name or account.

Vaccination: A Necessary Precaution Essay -- Medicine Vaccines

The issue regarding vaccinations and their accompanying side effects has been a prevalent debate throughout society and medicine for a number of years. Some continue to believe that vaccinations are harmful and actually promote disease, but the truth is that the concept of immunization is one of the most significant advances in scientific history that has led to the prevention of countless diseases and epidemics throughout the world. Still, despite the overall improvement of public health, the usage of vaccinations remains a controversial concern that is constantly challenged. Vaccination critics argue that the serious side effects associated with vaccines have been underreported, underfunded, and rarely researched. This, however, is false. Vaccinations are a necessary part of society because they prevent the spread of major diseases, reduce the severity of illness, boost one’s immune system, and in turn, protect the populous from potential epidemics. The definition of a vaccination, as stated by the Encyclopedia Britannica, is â€Å"a suspension of weakened, killed, or fragmented microorganisms or toxins or of antibodies or lymphocytes that is administered primarily to prevent disease† (Encyclopedia Britannica). Vaccines stimulate the immune system to attack the specific harmful agent and then cause the anti-bodies to remain sensitized in case the agent should ever reappear in one’s system. Obviously, this can be helpful when trying to prevent disease, or any other illness for that matter, since the anti-bodies specific to that type of illness remain present in one’s body lest the illness returns. Since infants are extremely susceptible to infirmity, many are vaccinated as early as the first month of their life. This helps p... ...ubmed/11032190>. Encyclopedia Britannica.

Analysis of Child Development Research Essay

The purpose of the study was to compare the outcomes of youth in long-term foster care with a group of children who entered into foster care and were subsequently adopted before reaching the age of 7 (Vinnerljung & Hjern 2011). Previous research conducted by Bohman and Sigvardsson found that at the age of 15, foster children who had been adopted performed as well in school as their peers who had never entered foster care. Children who were still in foster care had poorer grades and more behavioral problems. This gave the first implication that differences in child rearing environments are a strong factor in the positive or negative development of a child. The study consisted of a sample of 3,951 Swedish children born between 1972 and 1981. Each child entered care before the age of 7, and they were tested periodically until age 26. Of these children, 899 were adopted before the age of 7, and 3,062 grew up in foster care for more than 12 years (before aging out of the program at the ag e of 18). Adopted children spent an average of 1.6 years in foster care before adoption, while long-term foster care children spent an average of 16 years in care. The control group consisted of (consensus) data collected from 900,418 children who were never adopted or in foster care. These groups were adjusted for confounding variables, such as parental mental health problems and substance abuse before and/or after birth, as well as for age at entry into care. The outcomes were measured by an intelligence test that consisted of four subtests: logical, spatial, verbal, and technical capabilities. The scores ranged from 1-9, with 5 being average and a higher score indicating a higher cognitive competence. Both experimental groups had weaker outcomes compared to the control population, but foster children measured lower than adopted children in school performance, educational achievement, self-support capability, and cognitive competence. Children who were adopted at ages 4-6 showed improvements in cognitive ability over time, and by their late teens typically scored closely to their non-adopted or fostered peers. Negative outcomes were found to be far more likely for those in long-term foster care, regardless of gender, while adopted children had more favorable outcomes for school performance, cognitive test scores, educational achievement, and reliance on public welfare. Foster children had, on average, lower grades and cognitive abilities. Half of fostered boys had very low or incomplete grades from primary school, compared to 1/3 of adopted boys and 1/5 of the control population boys. For girls, the data was 1/3, 1/6, and 1/12. Attrition rates for grades at the age of 16 were the following: 13.4% for long-term foster care children, 4.3% for adopted children, and 2.4% for non-fostered or adopted children. By the age of 25, around 30% of fostered boys and 25% of fostered girls had only received a primary education. This is three times that of the control population, and twice that of the adoptees. Similarly, more fostered children were dependent on welfare at age 25 than children of the control group or adopted children. PAPER TWO: Developmental outcomes after five years for foster children returned home, remaining in care, or adopted Similar to the first, this study compared the developmental outcomes of children who entered into foster care as infants and either returned home, were adopted, or remained in foster care long-term. The first years of a child’s life are critical for proper development, particularly because younger children are more easily influenced and have the highest levels of brain plasticity (Llyod & Barth, 2011). Furthermore, previous research has suggested that young children in foster care are at a developmental risk compared to their peers. It is possible, then, that either reunification or adoption might alleviate these risks. The sample consisted of 353 children who were initially tested at 13 months, then again at 18, 36, and 66 months. The assessments were conducted with the child and the child’s current caregiver (whether that be biological parent, adoptive parent, or foster parent). The child’s status at 66 months determined their group designation of adopted, reunited/in-home, or fostered. All of the sampled children had to have at least one allegation of maltreatment. Maltreatment was divided into type (physical, emotional, neglect), to adjust for confounding factors. Many different tests were used to assess cognitive and behavioral delays in the children. These included: the Vineland Adaptive Behavior Scales Screener (which screens for problems in adaptive behavior and daily living skills), the Pre-school Language Skills (which assess developmental domain of language), the Kaufman Brief Intelligence Test (which assess cognitive development in children over 4 years), the Woodcock-Johnson III tests of achievement (which assess educational outcomes of children at least 5 years old), and the Child Behavior Checklists (which assess behavior problems in children ages 2 and older). Far fewer children in the adopted group were classified at high developmental risk. This group also scored significantly higher on cognitive stimulation and caregiver responsiveness. The foster care group had the lowest means in cognitive and language skills, but the highest scores in adaptive behavior. On these measures, adopted children and children who were returned to their homes scored relatively close to one another. There were no significant differences among groups in different poverty rates. In conclusion, reunification and adoption generally led to more positive outcomes, while long-term foster care typically resulted in poor developmental outcomes. These findings further suggest that adoptive placement specifically leads to improved social competence, language skills, and reading skills, but lower adaptive behavior development, while reunification mainly leads to better language development, math skills, and reading skills. PAPER THREE: Developmental, Cognitive, and Neuropsychological Functioning in Preschool-aged Foster Children: Associations with Prior Maltreatment and Placement History This study differs slightly from the first two by investigating the physical and cognitive developmental differences between foster children and children living with their biological parents. Typically, younger foster children display higher rates of developmental and mental health problems, which are often associated with maltreatment, multiple placements in foster care, and younger age at initial placement (Pears & Fisher, 2004). However, the majority of children receiving social and mental health services are over the age of 6, despite the fact that most children in foster care are between the ages of 2-5 years. Likewise, studies show that around 60% of the preschoolers entering foster care receive no treatment for developmental delays. The sample consists of two groups of children: the first consisting of 99 3-6 year old foster children, and the second of 54 non-maltreated, same-age, comparable SES children living with their biological families. There were no major differences in mean child age, gender, or ethnicity between the two groups. Height, weight, and head circumference were used to measure physical growth over time. Neuropsychological function was tested with the Developmental Neuropsychological Assessment, which includes 11 subscales in five domains: visuospatial processing (visual and spatial information processing), memory and learning, sensorimotor function, language, and attention/executive function. Cognitive function was measured with the Weschler Preschool and Primary Scales of Intelligence-Revise. Auditory comprehension and expressive communication were measured with the Preschool Language Scale-Third Edition. Executive function was further measured with two different tasks: the stroop task, where, when a card with a sun on it is held up, the child must say day, and when a card with a moon on it is help up, the child must say night; and the card sort task, where the child must first sort cards according to the shape on the card, and then according to the color of the shape on the card. Height for age was positively associated with memory and language in both groups, although the correlation was slightly stronger in the foster group. Foster children were, in general, shorter and lighter, and had smaller head circumferences than same-aged children in the control group. Children in the control group scored higher than foster children in visuospatial functioning, language, and general cognitive functioning. There was a moderately positive correlation between the age at which a child was first placed into foster care and the child’s executive function. Children placed in foster care before the age of 2 scored significantly lower on visuospatial processing, and children with more than the average number of placements had lower scores on executive functioning. IMPLICATIONS AND POSSIBLE INTERVENTIONS All three of the studies show that children placed in long-term foster care typically have more developmental delays and behavioral issues than children who are adopted, reunited with their biological families, or never enter foster care in the first place. A general conclusion can be made in that foster children need higher quality care and support from their foster parents, caseworkers, and doctors. The negative educational trends found by Vinnerljung and Hjern (2011) suggest that foster children received less satisfactory support in their schoolwork than adopted children. Foster parents and caseworkers could benefit from lessons in how to interpret a child’s behavior, nurture the child, and create a supportive learning environment for the child. This is especially important for younger children. Limited caseloads for social workers would allow for workers to concentrate on children and spend more time ensuring that they are receiving proper care. It is also clear that foster children would benefit from more early intervention services. Early development, as discussed by Lloyd and Barth (2011), is rapid and easily influenced by environment and quality of caregivers. Intervention services could prevent developmental delays, and lessen preexisting ones. Currently, resources within the system are limited, and largely consumed by older foster children. This is assumed to be because as children age, they become a larger threat to themselves (by displaying instances of self harm, suicide, increased violence, etc.), and thus, are referred to mental health specialists. However, most of these behaviors stem from existing conditions present at a younger age, and would be more easily controlled if addressed at the younger age. It would then also be important that these children receive consistent, satisfactory health care. Screenings for developmental delays and other behavioral problems would increase the ability to catch these problems early on, and treat them when the child is still young, and potentially easier to help. As well, because foster children are constantly changing homes, it would be important to maintain records of these screenings, so that the information is always readily available to caregivers, caseworkers, and doctors. This will ensure that the child is always receiving appropriate care. All three studies show the negative association between long-term foster care and a child’s development, even with skilled caregivers and placement stability. Working toward the preservation of families and the avoidance of placement in foster care may benefit the child developmentally. If necessary, the child may be removed from the home for a period of time, but there should be increased efforts made to reunite child and parent. Increased programing for parents (rehab programs, teaching about early childhood development, etc.) could increase such potential. References Llyod, C., & Barth, R. (2011).

Racism

Racism Racial prejudice has started since a very long time ago and unfortunately it still exists in today's society. People shouldn't be judge because of their skin colour but instead for what they did. In this article, it says that African Canadian drivers are being stopped at much higher rates than other races. If black people get arrested for something they did and white people do the same thing but get away with I think that it's extremely unfair and it is an injustice to these people who are getting arrested.Even though our skin colour may be different, our feelings are still the same. Black people and white people should receive the same treatment and decisions towards these people should not be based on their ethnic background. All these differences about colour are only skin deep and people should try and see what's on the inside of those people. I don't think that anyone likes be victim of racial prejudice and I don't understand why some people keep doing it to others.'RACISM/THERE IS MORE TO LEARN' Dominic JacquesHowever, in some cases aggravation is only created by the mental thought. Change is a particular device that people cannot handle at all times. People are more comfortable around the recognizable and they find it hard to adapt to a culture that they are not familiar being with. Since 1987, Chinese have been settling in Vancouver, as the suburb of Richmond went from one in twenty to one in three of its residents being Chinese, in two decades. This rapid change was not acceptable for many people who moved out for that very reason so they can live in a "white town" again (Rupet 1996,13-15). On the other hand, one does not have to be a racist to increase the racism around them. For example, silence does not necessarily mean it can prevent... Racism Racism Racism Racism could be a persons belief that one race is better than the rest. Racism comes from ancient times but todays people arent as open about it. Some people are racist against the color of someones skin or even their religious beliefs. American History X is a movie that can make racist people take a look at themselves and how they view other people and other ethnic groups. The movie starts off with an apparent message that is racism against African American people. Derrik becomes a young so called Nazi skinhead when his father is killed by an African American drug dealer while putting out a fire. Derrik encourages his little brother to follow the same beliefs that he does. Thus, this essay seeks to explore racial identity threat and how it has affected integration in the American society from historic times to date. In the film, American History X,Derrik gets arrested for killing two African American boys for trying to take his truck. While in prison Derrik joins the white crew for protection, he then sees that they still do business with other races so he gets offended. The main leader of the gang gets mad and decides to teach Derrik a lesson and orders the other white brothers to rape him in the shower. Derrik is then paired up to work detail with an African American guy who begins to let Derrik see another perspective on different races because Derrik is no longer protected from the white gang. He can only become a target for all other gangs in prison but his new found friend secretly protects him until he is released. The Neo Nazis in the movie represent a gang of white skin heads who scorn and hold rage against African Americans and other minority groups; something that has threatened harmonious co-existence of races in the American society for long. Derrik tells Danny what happened to him in prison and this seems to change the way Danny thinks and he agrees to change. Danny says, I hate anyone that isn't white Protestant They're a burden to the advancement of the white race. Some of them are all right, I guess... Danny is very selective and has a very negative reaction towards the blacks as influenced by Derek. He thinks that the white race should be recognized as the race that matters. For Danny, racism and anger becomes poison to him. It eats him from the inside. He thinks that hating an individual is a weapon that harms the person who hinders their progress. However, hatred through racism is like a curved blade. The racial harm that they both do, takes a very huge turn on his life. Racism has caused detrimental effects on characters like Danny when he goes to school on one occasion. This takes place after he visits the washroom where an African American student shoots him several times in the chest instantly killing him. This hate has reached great levels of murder. The African American kills Danny because of his race. At some point, Bob Sweeney tells Derrik, There was a moment, when I used to blame everything and everyone for all the pain and suffering and vile things that happened to me, that I saw happen to my people. Used to blame everybody. Blamed white people, blamed society, blamed God. I didn't get no answers 'cause I was asking the wrong questions. You have to ask the right questions. This shows how people regard themselves better than others. They always think that their race is superior and that other races are merely a source of trouble. Well, Amy Tan, on the other hand, describes what is seen as an American child staying with foreign parents which is highly comparable to an American child staying with English speaking parents. This is well described in Mother Tongue. Amy has all along lived the rest of her life with her mother who speaks English that is influenced by Chinese language. Racism still remains to be their challenge. People can easily look down upon them because they cannot speak good English. She explores the neglect she faced from the English teachers, but finally succeeded and ended up being a writer. This is an indication of how racism has affected her because she cannot speak English well at first. Amy is not at ease with her mother speaking English in the public. Amy shows how people can be despised if they are found limited in speaking English. They feel that their race is inferior. She refers to her mothers English as broken language. Failure to understand English well within the American society for immigrants can lock many doors of success and deny them many things owing to their race. The English speaking races are presented as superior than those struggling to make a sentence in English. Creating a good image is very important in getting what a person wants. Speaking good English was one of the ways for an immigrant to succeed in the American society (Mukherjee 126-129). Amys mother chose to let her speak over the phone on her behalf, especially when it involved serious matters. This is more in particular at a time when her mother wanted to speak to a stockbroker from the New York City. Amy says, When I was fifteen, she used to have me call people on the phone to pretend I was she (78). Amy Tan is a daughter of one of the immigrants into California from China in the end of 1940s. Though she knew Chinese, it was not enough to propel her to success in the United States. She ponders on the subject of learning English, as it takes a center stage and connects well with her success. She uses her book, Mother Tongue, to explore on this issue that has troubled many immigrants in the United States. Many arrive without having a good mastery of the language, but it has proven to be difficult living in America with such a condition (Mukherjee 126-129). Amy did not only want her mother to be despised in the public, but she helped her a lot in getting what she wanted from people across the American society. Although Amy stresses on the language that a family speaks and how it relates to shaping the childs language, the importance of speaking good English in the American society is very much evident. They are making every effort to move away from their race as it is hampering thei r endeavors in the American society. Conclusion American History X is a great example of a racist person seeing the different view of races after being turned away from his own kind. There is always going to be racism around the world. It would be nice if people could see the error of their ways just like Derrik. People are also racist because all nationalities are stereotyped an example is being Jewish people. Jewish people are believed to be cheap, African American and Hispanics are believed to be criminals and living off welfare whereas Italians are all believed to have mob connections, so if we cant get people to stop stereotyping they wont stop being racist. People have a formed opinion concerning a particular race and they treat people based on these stereotypes as seen in the American History X film. Amy Tan shows the same characteristics. As implied in her book, Mother Tongue, the failure to learn English would amount to despise and limited opportunities for the immigrants. This is a subject that has been debated upon concerning American being a place where cultures melt away occasioned by the fear of racism and its ravages. Amy shies away from her Chinese origin and language so that she can comfortably live within the American society with her mother. Apparently, it is true of America today. It appears as though it is a requirement for immigrants to learn English and somehow adopt American culture if they are to experience success in their new homeland, in the United States. Otherwise, the immigrants are bound to racism and will consequently hamper their efforts in the American society.

Why You Should Get a PhD in Chemistry

Why You Should Get a PhD in Chemistry If you are interested in a chemistry or another science career, there are multiple reasons why you should consider pursuing your doctorate or Ph.D., rather than stopping at a masters degree or a bachelors degree. More Money Lets start with a compelling reason for higher education money. There is no guarantee that having a terminal degree will earn the big bucks (dont get into science for money), but there are several states and companies that compute salaries based on education. The education can count for several years of experience. In some situations, a Ph.D. has access to a pay scale not offered to persons without the terminal degree, no matter how much experience he or she has. More Career Options In the US, you cant teach college-level courses without at least 18 graduate hours in the same field of study. However, Ph.D.s technically can teach college courses in any field. In academia, a Masters degree may provide a glass ceiling for advancement, especially to management positions. The terminal degree offers more research options, including some lab management positions not available otherwise, as well as post-doctoral positions. Prestige In addition to getting the Doctor in front of your name, having a Ph.D. commands a certain level of respect, particularly in scientific and academic circles. There are individuals who feel a Ph.D. is pretentious, but with work experience too, even these folk usually concede a Ph.D. is an expert in his or her field. More Affordable Education If you are seeking a Masters degree, you will probably have to pay for it. On the other hand, teaching and research assistantships and tuition reimbursement usually are available for doctoral candidates. It would cost a school or research facility considerably more money to pay outright for such skilled labor. Dont feel you have to get a Masters degree before pursuing a Doctorate. Different schools have different requirements, but a Bachelors degree is usually sufficient to get admitted into a Ph.D. program. Its Easier To Start Your Own Company You dont need a terminal degree to start a business, but credibility comes with that Ph.D., giving you a leg up gaining investors and creditors. Lab equipment isnt cheap, so dont expect people to invest in you unless they believe you know what youre doing! Reasons To Not Get a Ph.D. in Chemistry While there are good reasons to pursue a doctoral degree, its not for everyone. Here are reasons not to get a Ph.D. or at least to delay it. Long Term Low Income You probably didnt finish your bachelors and masters degree with a lot of excess cash. It might be in your best interest to give your finances a break and start working. You Need a Break Dont go into a Ph.D. program if you already feel burnt out, since it will take a lot out of you. If you dont have energy and a good attitude when you start, you probably wont see it through to the end or you may get your degree but not enjoy chemistry anymore.

Air legislation Essay Example | Topics and Well Written Essays - 500 words

Air legislation - Essay Example The center of gravity of an aircraft is its central imaginary point where it would balance when suspended. This point is important because it helps to determine an aircraft’s elevator effectiveness and stability and has an effect on the aircraft’s performance. For a successful flight the center of gravity should always fall within the stated limits provided by the aircraft’s manufacturer. These limits are the stated lateral and longitudinal limits where the center of gravity an aircraft must be situated during flight and is indicated in the aircraft’s manual. A change in the aircraft’s forward center of gravity increases the stability and the aircraft behaves as if it is heavier. This makes the aircraft to resist movement to outside forces. With the forward movement of the center of gravity, the aircraft is heavier on the nose. Change of the center of gravity from its required forward limit makes the elevator to be unable to hold its nose up especia lly during takeoff, landing and power-off glides. Performance of the aircraft decreases with a forward center of gravity. This creates a greater downward power on the aircraft’s tail needed to maintain the level cruising flight. This makes the aircraft to soar at a greater angle of attack which leads to a higher indicated stall speed and a more drag. An aft change of the center of gravity decreases the aircraft’s stability because the aircraft becomes more unstable as the center of gravity moves to the aft. This is because the elevator has a short arm distance from the center of gravity and therefore it needs a more deflection to produce an equal result. Stall recovery is almost impossible as the aircraft’s tendency to pitch down has been reduced. Moving the center of gravity beyond the aft limit makes the stall and spin recovery difficult. Change of the aft center of
