Learning Disabilities Essay Example | Topics and Well Written Essays - 500 words

Learning Disabilities - Essay Example The study consisted of a sample from seven schools of 1,361 consenting elementary students (678 girls, 683 boys; 55 with LD) of which data was collected two months into each semester beginning in the spring of 3rd grade and ending in the fall of 6th grade. All 55 (34 boys, 21 girls) of the children diagnosed with learning disabilities were in inclusive classrooms. The study included a meta-analysis of intra-group functioning, the features of the peer group in relation to its member size and its standing within the classroom, and 3 other components: being popular, peer nominations for best friend, and social preference. The results from the multiple measures of social functioning yielded that although LD students were members of a peer group with similar features as typical students, and at a similar rate, these students had lower statuses in regards to the classroom as a whole. These same distinctions remained consistent throughout the study period despite the fact that all classrooms were inclusive. Limitations of this study include the sample size of LD students and the certain context-elementary school-as these distinctions may fade in other areas or ages.

Case study report Statistics Project Example | Topics and Well Written Essays - 1000 words

Case study report - Statistics Project Example   This paper will review some of the key elements of the law. These elements include: Since the enactment of the proposition 209, diversity in Californian schools has marginally decreased and the amendment is aimed at increasing cultural diversity in Californias higher education institutions. A key analysis of the topic, however, indicates that there is a possibility that the introduction of the act would not only hinder the progress and development of diversity in Californian institutions, but also would primarily motivate racial profiling in the public school system. Regardless, this does not automatically make Proposition 209 more appropriate than SCA5. Even so, it shows that the policy has been effective and as such, there is no need to eradicate it completely from the system.    The first reason why the amendment would not be introduced effectively into the system is the consideration of the various changes that have taken place since the enactment of the Proposition 209, that hindered all Californian offices, schools and employment opportunities from considering race, sex, gender and age when selecting people. Currently, several universities around the country practice the affirmative action clause proposed by the amendment, but these same universities have not violated the Equal Protection Rights (Joe Gardner’s State Assembly, 2014).    The blacks, the Hispanics and the Asian-Americans are the worst affected if the bill is passed. Primarily, the racial profiling or preference in the selection, according to the proposing parties, would allow schools to slowly select and promote an equal selection criterion if properly enforced. The enactment of the policy, which directly opposes the Proposition 209, which was enacted in 1996 and which has been a little fruitful now. Most people fail to see the reason

Is it possible to be Muslim feminist Essay Example | Topics and Well Written Essays - 5000 words

Is it possible to be Muslim feminist - Essay Example This is especially due to the rise of women’s rights awareness throughout the world. However, what is neglected when feminist related issues are discussed regarding Islamic oppression of women is the situation of women throughout the world in contemporary times which led to the need for a separate feminist movement. Simultaneously, the situation of women in the past and in the pre-Islamic era also needs to be given sufficient weightage in order to understand the notions of modern day feminism and the teachings of Islam. Firstly, let us take a look at the situation of women in Pre-Islamic Arabia. The women at the time were not considered a part of society. Rather they were considered assets, possessions and ornaments to embellish, use and discard as a source of masculine power. The culture which was largely prevalent at the time was a tribal. But not a kind of tribal culture which is visible in our current day world situation, as for instance, in war-torn Afghanistan. The tribal culture’s motto was to put first, and foremost, the unity and brotherhood of the tribe. The tribe was an entity in its own right. However, it did not have the infrastructure that any highly developed society of modern times would have. Individual rights and properties were not maintained rigidly since the clan consisted of all blood relatives. The property, which included women, remained within the bonds of the tribe and its authority figures who were known as the ‘sheikhs’. Female infanticide was a common practice of the time. Female children were considered disgraceful and unwanted. Male children represented a form of power, wealth, and richness in fertility. As the sole heir of the family they were given full property rights as daughters were being swiped off from the face of the earth. But the main reasons behind killing female infants were relevant to poverty, pride, and the avoidance of

The Verification Principle Essay Example for Free

The Verification Principle Essay Throughout the years, science has been a very productive practice. From explaining why and how things happen to sending people to the moon. Not only do we see its benefits every day, but also new discoveries are being made constantly. Science has proven its success. By using the scientific method and critical thinking, a wide range of things have been discovered. One cannot say the same for philosophy. Many of the questions that were asked by the very first philosophers are still being contemplated and debated over today. Some philosophers thought that in order to make philosophy as successful as science that they would need to adopt a method such as the scientific method. Thus, the Verification Principle came to be. The philosophers with this idea that philosophy needs to be successful, like science, were the logical positivists. These philosophers had a â€Å"scientific envy,† wanting to make philosophy more scientific. Their method to become more â€Å"scientific† was to create the Verification Principle. It states that â€Å"A statement is cognitively meaningful if and only if it is either analytic or in principle empirically verified. They thought that if something cannot be verified analytically or by experiment, then there is no need to debate about it. To understand this principle, one must understand some of the key terms and concepts in it. Something can be described as cognitively meaningful if it can be found to be true or false. Therefore, a statement must have a truth-value. According to the Verification Principle, in order to find if something is true or false, it must be analytic or in principle empirically verified. Something is analytic if it can be found by mathematical means or by using logic. Twenty divided by two equals twenty-two is an example of an analytical statement. Whether the statement that twenty divided by two equals twenty-two is correct, or not, by using mathematical reasoning, the answer can be found to be true or false. Another example of an analytical statement would be as follows: â€Å"A guitar is a musical instrument, and musical instruments sound beautiful. Thus, a guitar sounds beautiful. † Since the argument flows in a logical pattern, the statement is said to be analytic, and therefore, also cognitively meaningful. The last part of the Verification Principle states that a cognitively meaningful statement must be in principle empirically verified. For something to be in principle empirically verified, it must be able to be, in theory, proven experimentally. For instance, the statement, â€Å"Hell is located in the core of Earth,† can be empirically verified. Although it has not yet been proven or disproven, theoretically it could be. Although challenging, I am sure, but eventually we could somehow get a person, or group of people, to dig deep enough and then see if our core is in fact â€Å"Hell. A new and revised Verification Principle would be as follows: A statement can be found to be true or false if and only if it can be found using mathematical reasoning, logic, or if it can be found in principle experimentally. If a statement is not found to have a truth-value using any of these methods, then it is said to be cognitively meaningless, and consequently, does not need to be discussed. The statement that â€Å"God exists† would be considered cognitively meaningless. It cannot be proven mathematically, or logically, that God exists. Nor can it be proven with any type of experiment. Since it is cognitively meaningless, there is no need to debate God’s existence. According to the Verification Principle, many philosophical concepts and questions no longer need to be discussed. One relevant subject, that would be deemed cognitively meaningless, is Ethics. Many if not all statements, or questions, in Ethics cannot be determined analytically or empirically verified. As such, Ethics should no longer be discussed. Whether a person murdering in the name of patriotism or defending one’s own life is ethical, is pointless to debate because it has no truth-value. A mathematician cannot figure out using a formula whether these acts of murder are ethical. Neither can a person use logic to find the answer. It would be absurd to think that a person could determine the answer to the question using an experimental method. Ethics in general, becomes pointless to discuss. Many have objected to the Verification Principle since many things, are considered cognitively meaningless, but do require attention and discussion. Axiology, which asks the question â€Å"What are values,† is completely â€Å"cognitively meaningless† under the principle. Some would say that this could not be correct since values are imperative. Values create a sense of character, personality, and meaning. Surely, we should not just throw out the whole study of what our values are because the answer to the questions cannot be found analytically or by experiment. David Hume brings up a valid point that contradicts the Verification Principle, stating that the principle itself is self-contradicting. Hume points out that science relies on principles that cannot pass the Verification Principle. By the logical positivists trying to mirror the success of science, they created a principle that even the principles of science do not pass. One such principle is the Principle of Induction. This principle, in crude terms, states that the future will resemble the past. According to the Verification Principle, this statement is cognitively meaningless. Once again, neither mathematics nor logic can be used to determine a truth-value to this statement. It also cannot be proven in principle by experiment. Since we are always in the present or looking back into the past, we cannot say that the future will resemble the past, but science bases its rules, theories, and discoveries on this principle. Another scientific principle that does not pass the Verification Principle is the Principle of Universal Causation. It states, also crudely, that every event has a cause. Since there is no way to experimentally determine that every event that has ever happened, or will happen, has a cause, it is cognitively meaningless. Hence, if the Verification Principle is correct, then science itself is cognitively meaningless and does not need to be debated nor discussed. In my opinion, the Verification Principle is not a valid basis on which to determine whether a subject should be discussed or not. Many things, such as ethics, need to be discussed. If we chose to follow the guidelines of the principle, there would be no need to discuss ethics. This would in turn eventually cause people to forget what ethics or an ethical judgment is. There would be no sense of what is good or bad; only who has the bigger gun. Society would be reduced to animals, though we are already close to that point. By people discussing ethics, and ethical judgments, though we may never reach a conclusion or agreement on some aspects of the subject, we choose to not forget about what is just and that there is a difference between right and wrong. Though philosophy may not have all too much to show for all of its work, at least if compared to science, then at the very least it causes people to think for themselves and to not forget about things which are important to human nature. Such things as religion, ethics, values, and creativity are all important to us as humans. If using the Verification Principle, all such things would be â€Å"cognitively meaningless. † In a way, it is the things that are â€Å"cognitively meaningless† that are more important than the â€Å"cognitively meaningful. They are what define us and not only set us apart from all other species, but also from each other. In conclusion, the Verification Principle was a way for some philosophers to make philosophy successful much like science. The principle states that â€Å"A statement is cognitively meaningful if and only if it is either analytical or in principle empirically verified. † Many things in philosophy, such as Ethics, in this sense are â€Å"cognitively meaningless† and should not be discussed. David Hume pointed out that science is based on principles that do not pass the Verification Principle and is therefore â€Å"cognitively meaningless. To be fair, the Verification Principle was a poor attempt to try to put a value on the success of philosophy. The greatness of philosophy though, is that it is not based solely on numbers, logic, and experiments, but also on critical thinking. It is that aspect of philosophy that sets humankind apart from the rest of the animals on Earth. Although some of the questions of philosophy may never be solved, the true success of philosophy is that it causes people to think and to search for answers instead of accepting what they have always â€Å"known† as truth.

Aspects Of A Vehicle Clutch System

Aspects Of A Vehicle Clutch System P1 P2: Demonstrate the knowledge understanding of the fundamental aspects of a vehicle clutch system. A clutch connects disconnects one rotating mechanical component from another: a clutch transmits torque from the engine to transmission. Most light vehicle use a single plate clutch to transmit torque from the engine to the transmission input shaft, the fly wheel is the clutch driving member. The clutch unit consists of a friction type disc with two friction facings a central splined hub. A pressure plate assembly consists of pressed steel cover with a segmented diaphragm spring a release bearing with a selector fork. The amount of torque a clutch can transmit depends on the co-efficient of the friction between the friction facings their mating surface, thus increasing the diameter of the clutch increases it torque capacity as does increasing the spring force. The transmission input shaft passes through the centre of the pressure plate. Its parallel spleens engage with the internal splines of the central hub, on the friction disc allowing torque to be transmitted from the flywheel, through the friction disc to the central hub to the transmission. When the clutch pedal is depressed, the movement is transferred though the operating mechanism (this being cable, hydraulic or electronic system), to the operating fork release bearing, the depressing movement acts on the releasing bearing moving it forward pushes the centre of the diaphragm spring towards the flywheel, the pressure plate disengages, thus drive is no longer transmitted. Releasing the pedal allows the diaphragm to re-apply it clamping force thus engaging the clutch thus restoring drive. This control is necessary when placing the transmission into gear; the transmission input shaft must be disconnected from the engine. Types Of Clutches: Single Plate Transmission Most modern vehicles use single plate clutch system to transmit torque from the engine to the transmission input shaft, the clutch unit is mounted on the flywheel, allowing the unit to rotate with the flywheel. A single plate clutch unit usually consists of a friction plate with 2 friction facing a central splined hub, a pressure plate assembly which consists of a pressed steel cover, a pressure plate with a machined flat face, a diaphragm spring, release bearing release fork. Pressure Plate: It mounts on the flywheel. It consists of four main parts is more correctly called a clutch cover assembly. These parts are the pressure plate itself, the springs (or spring, if a diaphragm type), the clutch cover, the release arms. There are two basic designs of clutches usually referred to by the spring type. This diaphragm is located inside the clutch cover on 2 fulcrum rings, held by a number of rivets passing through the diaphragm. The diaphragm type clutch works well in lightweight, low geared vehicles. It is not the best clutch for high RPM use as the diaphragm spring will stay flat or released from the centrifugal force generated by the RPM. Clutch Disc/Friction Plate: This is the driven part of the clutch. It has a friction material riveted to each side of a wavy spring. This is attached to a splined hub that the transmission input gear protrudes into. There are basically two common types of friction material used for clutch lining. These are organic metallic. The organic is best for all around use. The metallic is preferred by some for severe duty applications but requires high spring pressures is hard on the flywheel pressure plate friction surfaces. Clutch Release Bearing: As its name implies, this is the bearing that releases the clutch. Because the release bearing only works when the clutch is being released it usually lasts quite a long time. However, improper linkage adjustment can wear the bearing prematurely. Normally there should be a minimum clearance of 1/16à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ã‚  between the face of the bearing the three release fingers or diaphragm spring of the pressure plate when the clutch is engaged. Clutch Release Fork: This is the arm or lever that the linkage operates that moves the release bearing. There are several different styles of release arm. The most common type the can be found in a vehicle is the fork type. Bell housing: This provides a mounting place for the transmission, as well as a means of aligning the transmission to the engine. In some applications it also has a structural mounting function. Operating Mechanism: The movement at the pedal is transferred through an operating mechanism to the clutch assembly; the mechanism may be mechanical or hydraulic. Mechanical system uses a combination of levers cables thus offering more flexibility, thus making this system very common. The cable operated control (Image) for a front wheel drive vehicle; the outer cable is fixed to the pedal to the pedal box inside the vehicle to the clutch housing in the engine compartment, the inner cable connects between the upper end of the clutch pedal an external lever on top of the clutch housing. This lever is connected to a vertical shaft, supported in the housing attached internally to a release fork, which carries the release bearing. In hydraulic clutch control, the pedal acts on a master cylinder, connected by a hydraulic pipe and flexible hose, to a slave cylinder, mounted on the clutch housing. The slave cylinder operates the clutch release fork. This vehicle uses a centre valve master cylinder. With the pedal in the off position, the centre valve is clear of the inlet port and fluid can flow to or from the reservoir, into the cylinder. Dual Clutch Transmission There are two basic types of transmissions, manuals which require a driver to change gears by depressing a clutch pedal, automatics which do the shifting work for drivers using clutches, torque converter sets of planetary gears. But the dual clutch transmission brings the best of manual automatic transmission. A dual clutch transmission offers the function of two manual gearboxes in one, a dual clutch gearbox, uses two clutches but has no clutch pedal, instead electronics hydraulics controls the clutches. Has in result one clutch controls the odd gears (First, Third, Fifth Reverse), which the other controls the even gears (Second, Fourth Sixth), although the gear controls may vary from designs to manufacturers. Gears can be changed without interrupting the power flow from the engine to the transmission. A dual clutch unit usually consists of a friction plate with 2 friction facing a central splined hub, a dual clutch case, pressure plate assembly which consists of a pressed steel cover, a pressure plate with a machined flat face, a diaphragm spring, release bearing release fork. Wet Clutch: Like torque converters, wet clutches use hydraulic pressure to drive the gears. The fluid does its work inside the clutch piston. When the clutch is engaged, hydraulic pressure inside the piston forces a set of coil springs part, which pushes a series of stacked clutch plates and friction discs against a fixed pressure plate. Single Plate Clutch Vs. Dual Clutch Transmission: Single plate clutch offers many advantages drawback over its counterpart dual clutch transmission: Advantages: Low manufacturing costs Lightweight Spare part easily accessible Easy maintenance comparing to dual clutch transmission Reliable due to few components Disadvantages: Unreliable in heavy duty vehicles High clutch wear (requires more slip to pull away from a dead stop) Drop of RPMà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s during quicker up shifts Dual clutch transmission offers many advantages drawback over its counterpart single plate, as listed: Advantages: Very reliable in heavy duty vehicles. Robust system compared to the rack pinion Quick precise gear change without loss of RPMs Improved MPG (miles per gallon) range Disadvantages: Heavier in weight compared to single plate transmission Large amount of components High manufacturing costs Complex in fitting in a vehicle Maintenance required frequently When comparing the two both systems, each system has its advantages drawbacks, but in the end each system has certain properties which are suitable for the vehicle is intended for, but when putting in real world application dual clutch does have some advantages over single plate transmission, due to its ability to improve MPG range, which could be a big factor for manufacturers to opt with dual clutch system over single plate over for high end to sport car, but due to its high manufacturing costs components weight , dual clutch system may take time to take over single plate system has the most common system, so in conclusion the single plate may be good system for possible next five years, but dual clutch may become common after, due to its single highest factor of improved MPG range.

Machinery Hall, Centennial Exposition 1876, Philadelphia Essays

Machinery Hall, Centennial Exposition 1876, Philadelphia The "International Exhibition of Arts, Manufactures, and Products of the Soil and Mine, in the city of Philadelphia" was opened on the 10th day of May in the year 1876. As it was more commonly known, the "Centennial Exposition" was America's first successful World's Fair. The fair celebrated the one hundred year anniversary of the Declaration of Independence and America's start as a sovereign nation. It was at the Centennial Fair that Americans were given a chance to display their knowledge and power in the growing industrialized world. Long gone were the days of single-structure exhibitions. The Philadelphia organizers peppered Fairmont Park with exhibition buildings and attractions, giving visitors much to look at. At the fair the United States sought to establish itself among the major countries of the world. The major buildings of the fair: Memorial Hall, the Main Building, Machinery Hall, Horticultural Hall, the Women's Pavilion and several national and state pavilions provided a suitable architectural framework for the exhibited materials. The most popular of these buildings was Machinery Hall, built to house the country's technological wonders of the past century (Snyder). Machinery Hall, "four times the space of St. Peter's" in Rome (Bruce, 150) covered an area of 558,440 square feet (including its annex). Fairmont Park was at the time the "largest and finest urban park in America" (Mass, 16). After selecting the site for the fair, the Centennial Commission held a competition for the design of the exhibition buildings offering awards to the top ten entries.
