Inside A Pre K Classroom Education Essay

Inside A Pre K Classroom Education Essay In a Pre-K classroom how and what the children are taught is very important. This is when the foundation for learning in a school setting is experienced. The type of training the teacher has in early childhood education is imperative as well. The above factors work together to help the class have successful learning experiences. In this paper it I will discuss the theories and/or philosophies that reflect how I envision my classroom and curriculum for pre-k. The concepts I would teach in each of the academic area, and finally I will include two activities that I would do with the class that coincides with the philosophies of the National Association for the Education of Young Children Standards. There are a couple goals I would keep in mind as pre-k teacher when setting up my class. I d being able to provide a planned educational environment, which means not just teaching as I go. But actually use what I ve learned in classes, workshops, and other resources to provide the best learning environment possible. Secondly, make sure learning experiences are plentiful, so that a positive foundation for the future is supported. Some of the motivations behind my goals are coming from the works and studies done by earlier pioneers of education. One of them that definitely come to mind is German educator Friedrich Froebel (1782-1852) who was renowned for his pioneering work in developing a school for early childhood education. He was a philosophical idealist who believed that every child s inner self contained a spiritual essence that stimulated self-active learning in curriculum for kindergarten. (Eliason Jenkins, 2012) Play was an appropriate means of learning to Froebel. The time c hildren spend drawing, using manipulatives, sing songs, and finger plays it was allowing them to learn. The other pioneer that comes to mind is Jean Piaget (1896-1980) a Swiss psychologist, which made significant contributions to educational psychology and early childhood education. (Eliason Jenkins, 2012) He felt the teacher is designer of activities appropriate to child s level of development. Piaget s principle which states its through children s own exploratory processes, they are able to develop the power to generalize, differentiate, and coordinate their concepts of reality, building concepts based on their experiences of the external world. (Berk, 2003, pg. 219) Their understanding of the world changes as they grow. It s these theories and others from earlier educators helped us today and in the past get a better understanding of the children s development. Pre-K is where the experiences learned can help them develop a positive self-image along with the emotional, social, and intellectual skills necessary to be successful in the classroom. My curriculum would help create a stable foundation in the growth of independent learners. It s here that both teacher-directed and choice-based activities can create these independent learners. (Berk, 2003, pg. 342) The classroom s activities for the curriculum are designed to recognize the growth and development of each child while I m teaching. It will motivate the children to learn while also identifying the needs of the child individually. This way I m able to help them develop positive relationships with peers and adults, and encouraging them to express themselves creatively. They will get to develop language through listening, speaking, and dramatic play activities. The opening for physical growth can take place through gross and fine motor activities, also provide experiences to stimulate and develop cognitive skills. There are some basic concepts such as counting, colors, shapes, patterning, math, rhymes, and sequencing will be learned. Some of the academic areas of my class would include math, literacy, creative arts, science, and technology. Young children develop an everyday mathematics including informal ideas of more and less, taking away, shape, size, location, pattern and position. (Ginsburg, Lee, and Boyd 3-23) In math they will get the chance to learn things like numerals 1-10 and counting objects to 10. The children will learn to identify, describe and compare repeating patterns. This is actually the basis of our number system. The students get the chance to sort of objects such as color to help them to develop flexibility in thinking and problem solving. They will get introduced to shapes (circle, square, triangle, and rectangle), sizes (small, medium, large), shapes matching and time in reference to day and night. There is even an insight about using measurement. In the area for dramatic play there are pots, pans, and etc. to allow them to act out things they see in the kitchen. Well, when using the items they are able to try and see what fits into what and what doesn t. This is also allowing them to use problem solving skills. Literacy is what my class is able to read and write. It s at this age I know they can gasp good habits as their reading and writing level is starting to grow. My responsible is to create a literate environment and then use the best tools available to teach the components of literacy. (Eliason Jenkins, 2012) I will teach about each letter s name and sounds of the alphabet. They will work on spelling, writing, and recognizing their own name. Practicing writing will help them learn to hold writing utensils correctly. At this point they can understand and explain what the text in a story is about from its illustrations, repeat nursery rhymes and finger plays, respond to questions about stories, build new vocabulary and listening skills. The creative arts would defiantly be enjoyable when working with this age. They have such great imaginations that actually get to allow them to share it with each other. I would make sure while they are learning I embraces all of their creativity with positive reinforcement. I d let them try art processes like painting, drawing, sculpture, weaving, and collage. I would encourage them to sing songs that enhance their curriculum. During music time allow them to use scarves, rhythm sticks, and bean bags to practice rhythms. I encourage them to play with children s instruments. As we learn about different animals I d have the class act out the sounds they make. It s so many ways to bring out their artistic side but these are just a few I would do with them. In the science area they are at a developmentally appropriate age to explore science tools such as magnets, prisms, magnifying glasses, and etc. I can take them on nature walks, gardening, and other explorations. Plan activities where they can measure and mix ingredients in cooking activities. I can allow them to identify basic colors and explore color mixing to see how certain colors are formed. Teaching them about how we use our five senses to explore different things. Then there s sharing different types of animals with the class. But also going even farther by informing them about the types of homes they live in, and the food they eat. It seems that the world is become more and more dependent on technology as time goes by. Today even pre-k can get a start on using some of the devices. Computers play a huge part in our lives nowadays. My students would learn things like creating picture with computer programs to tell stories. They will be working on improving their fine motor skil ls by using the keyboard. Also while controlling the mouse to click and drag to different points on the screen. They would be allowed to explore kid friendly websites on the internet that is developmentally appropriate. The first activity I would do with them is called Autumn Collage The day before we do the activity I would complete an example for them to see. The materials needed are treasure sacks (brown paper bags), flour, oil, salt, and water for collage background, plastic spoons, heavy paper plates, hold puncher, and yarn. The morning before we go outside I would pass the sacks out and tell the children we are going on an autumn nature walk to look for treasure. The items we will be looking to put in our sacks are leaves, nuts, acorns, grass, small flowers, and seeds. The two objectives for my class will be to measure and mix ingredients for collage background, and sort and place items from their treasure sack onto the collage. Once back inside and we get ready to start the activity the procedure would go in this order select a paper plate and have students write their names on the back of their plate, discuss the word Autumn and that we are going to make a special display for the items they have in their treasure sacks, show how to measure and mix the glop for the collage background and how the mixture changes, then allow them to spread the glop onto the paper plate with a spoon, take items from the treasure sack and place it onto the glop to make a pretty autumn collage, and finally let the collage dry and explain how the water will evaporate and their collage background will get hard just like mine. I will then take finished collage to a drying rack. When it is dry in a couple of days, I will then punch a hole in the edge of the plate and put a yard through it so it can be hung. The concepts the children learn from this activity are fine motor, language development, measurement. The second activity I would do with my students is called Name that Sound . This activity is great to do for science to work on our sense of hearing. This can be fun and encourage the children to use their listening skills. It s also designed to make the class aware those different things that have sounds of their own. They are also able to learn we can name different things by recognizing the sounds with their ears. The materials needed for the activity are paper, chalk, pen, zipper, jar with screw lid, bell, book, and other objects that make noise. I would use this activity when we are working on learning about our five senses. Before getting into the activity I would go over some vocabulary words used during this activity. They would include words like loud, quiet, sharp, soft, and sounds. The steps for this lesson are to take turns with a group or with an individual; asking each child to close his eyes, wad up the paper while his eyes are closed and ask the child to identify the sound, and then repeat with a different object. Once completing this activity the children will become more aware of sound. The National Association for the Education of Young Children Standard (NAEYC) is a 103,000-member organization of early childhood educators. NAEYC has created a set of standards that specifies what a program s characteristics that meet the developmental and individual needs of young children of varying ages, based on current research and the consensus of experts. (Berk, 2003) The two planned activities above encourage the children to be active and engaged. (Berk, 2003) It is so important to Implement a curriculum that is thoughtfully planned, challenging, engaging, developmentally appropriate, culturally and linguistically responsive, comprehensive, and likely to promote positive outcomes for all young children. (NAEYC, 2003) You are now aware of how I would prepare the appropriate curriculum to teach a pre-k class. I have shared the goals of providing a planned educational environment, and creating rich learning experiences to form a positive foundation for the future. Plus, instructions on how the goals are applied in each academic area and two different lesson plans.

Ethics for Teachers Essay

Educators are held to a higher standard of behavior than other professionals. The behavior of teachers is judged more harshly. While some wrong behavior is excusable for others, unethical behavior is inexcusable for teachers. Teachers are authority figures, role models, behavioral examples and surrogate parents (Weldon 2003). In some instances the teacher is the only authority figure in a child’s life, so if that trust is broken where is a child to turn? There are many instances of unethical teacher behavior, I have found just a few. In school district 52 in B. C. two teachers are facing charges of sexual exploitation of students. One of the teachers was employed for five years and was charged on Dec. 23 with three cases of sexual exploitation of a young person (Schumacher, 2008). Another teacher was charged with two counts of sexual assault and two counts of sexual exploitation of a person with a disability (Schumacher, 2008). Upon the completion of the districts investigation the first teacher was fired with cause and the second teacher was suspended from his duties. Lisa â€Å"As with anything, it’s until something happens that you look a little closer at all of the policies that you have,† said Last. â€Å"I’m assuming as a parent and community member that here is a code of conduct for any teacher. Like doctors have their code of ethics, I’m assuming teachers have their own as well. †(Schumacher, 2008). Last is the chair of School District 52. After the charges the school district began reviewing practices to help avoid future issues. In Bakersfield, CA a teacher was charged with two felony counts of oral copulation with a person under age 18(Kotowski, 2008). â€Å"If we just say that we kissed that we made out, at most we made out we kissed we just kind of held and caressed each other ten that’s not statutory rape,† Neal said. â€Å"And that saves me from a hell of a lot of trouble. †(Kotowski). Neal told the student to lie about what had happened between them and was not aware that he was being recorded by police. He taught for 10 years and is on administrative leave. In Ontario a teacher had his license revoked because he made racist comments about Jewish people while he was off duty. â€Å"The Supreme Court basically said that, as a teacher, your off-duty conduct can impact on your roles as a teacher if what you’re doing is engaging in behavior that could create a poisoned environment within the school system,† said Brian Kenny, a lawyer with MacPherson Leslie and Tyerman in Regina. (Klie, 2007). He had been engaging in racist activities for years, but still kept his job until the board was sent a tape of him speaking at a Heritage Front rally in front of a swastika flag, extolling the virtues of a neo-Nazi who was convicted of violating the Canadian Human Rights Act. (Klie). Teacher’s returning to school in Woodstock, GA were greeted with a copy of Georgia school’s version of the 10 Commandments: the Teacher Code of Ethics. (Jonsson, 2001). During the summer one teacher was convicted of child abuse, while two others were indicted, they were soliciting students at school for sex. While there seems to be quite a few examples of sexual misconduct that is not all the unethical things teachers do. One teacher changed the answers to a test of a student because she felt she did not deserve to get promoted. Another teacher found that a student’s hyperactivity medicine worked so well she gave it to other students. (Jonsson). Teachers should be held to higher standards than everyone else they are molding the people who will one day be our future. I don’t agree that their life should be under a microscope, but I do agree there should be some standard of ethics that teachers should follow. References Jonsson, P. (2001). More school districts warm to lessons in correct conduct, hoping to stem a tide of ethical lapses. The Christian Science monitor, 11. Klie, S.(2007).

The Market For Generic Drugs - 1663 Words

Introduction The market for generic drugs has been increasing recently, with a large share of total prescriptions being dispensed in the United States. At the wholesale level, the generic drug market has typically been viewed as very competitive, such that prices approach marginal costs1. Therefore the availability of generic drugs is perceived as beneficial to consumers who have to pay for these drugs. However, at the retail level, generic drug prices seem to exceed marginal cost even by a wide margin1. In the last few decades, â€Å"the fraction of drug spending paid for by public and private payers has grown from 34% in 1980 to nearly 80% in 2000, and 92% in 2010. Thus cash-paying consumers currently account for only 8% of payments†1.†¦show more content†¦However, because the AWP is somewhat ambiguous and does not really provide a true drug-by-drug average price across major wholesalers, there is a lack of trust from the government and private payers regarding its validity3. Th e federal government, in an effort to establish a more equitable and uniform pricing platform for Medicare Part B drugs, elected to utilize pricing based on ASP3,5. Background Before the introduction of the AWP-based reimbursement by California s Medicaid program in 1969, its predecessor, the cost-based reimbursement was first used. This reimbursed pharmacies the exact amount they were charged by manufacturers to purchase the drug plus a fixed dispensing fee to cover labor and capital costs1. This resulted to multiple reimbursements amounts for identical products. More importantly, since pharmacies would receive the same profit margin from reimbursement regardless of their acquisition costs, drug manufacturers could in turn set high prices without reducing pharmacies demand for their product. This led to the introduction of the AWP-based reimbursement at a time when public and private insurers were just beginning to pay for prescription1. The AWP is a publicly available list price used as the basis for setting payment rates to pharmacies. The AWP is reported by generic producers themselves, and until recently has not been subject to any independent verification. Consequently, the AWP â€Å"is neither an average nor a price

Critique on the Criminal Justice System and Social Media

1. Interesting Points: a. An interesting point I found was the contribution of the criminal justice system to an ideology. The ideology is explained as the set of beliefs that formulate and justify the existing state of affairs and its unfairness. The message being conveyed by the criminal justice system is that the result of criminality is from a single persons weakness versus the inequities of the social class (177, 2). I find this interesting that the failures of the individual is being the pinpoint of criminality and that social inequity is being preserved in the doing so. b. The ones who suffer from the injustice of the criminal justice system and the failure of the reduction of street crime are the poor. The poor are not in a†¦show more content†¦The hostility towards the poor will not decrease and the circle of injustice will be never ending. b. Criminals are more likely to come from the lower class and that crime is labeled as crime of the poverty is another detail found in the ideological message (183, 3). This is problematic in that it promotes the poor being criminals and that there crime is due to the fact that they are poor. Because of one people are poor they must do what they can to survive, even if that means committing a crime. When they commit a crime, they are proving the society right about crime being of the poor. According to Reiman, crime is poverty and poor people committing a crime justifies that statement (183, 4). c. The last point I find problematic is the lack of evidence that Americans have sympathy towards the poor. There is lack of true knowledge of crime and many Americans do not believe that poverty is a main source of crime (191, 2). They do however believe that the poor are more criminal than the rich (192, 5). The problem with this is that Americans are living a lie and believing a non-truth of crime. They don’t care and have little sympathy for the poor, but the poor have so much sympathy for others who are caught up in poverty. 3. Specific Questions: a.

Switch Models for Managing Queue Length Matrices Free Essays

string(114) " weight factor additions with addition in HOL tenancy at input FIFO and hot-spot tra_c to label end product port\." Switch Model We consider an N _ N non-blocking, input bu_ered switch. Figure 4.1: Queueing theoretical account for a waiting line. We will write a custom essay sample on Switch Models for Managing Queue Length Matrices or any similar topic only for you Order Now The input I, has M FIFO waiting lines, qi1 to qiM, where 1 _ I _ N and M _ N. The length of every FIFO is assumed to be in_nite. N end product ports are divided into M reference groups each of N=M end products ports. When a package arrives it joins one of the M group, depending on the its finish. In the system that we consider, a package from an input I destined for end product port J is put into qij modM. The input tra_c is assumed homogenous and with Bernoulli distribution. Packages 91 4.2 Random Selection are distributed uniformly for all end product ports. Time is assumed to be slotted with each slot equal to the transmittal clip of a cell. In a cell slot, we have to choose a upper limit of N cells from MN FIFO waiting lines with non-conicting finish references. The manner in which these N cells are selected is decided by the cell choice policy. Di_erent cell choice policies are discussed in the following subdivision. Here we assume that at most one cell is selected from each input port, destined to a non-conicting end product. An e_cient cell choice policy should maximise the throughput and mini- mize package transmittal hold. It should besides be noted that the programming policy should be simple for execution. We present here di_erent cell choice poli- cies. A Queue length matrix L, of size N _N, is formed from current waiting line length of FIFO. The current waiting line length of each FIFO is assigned to Lij, where I is input port and J is the finish port of HOL cell.

( Figure 4.2 ( B ) . ) 4.2 Random Selection In this policy, in a cell slot, one of the random places of the cell is selected. If the cell is available it will be switched to the end product port. The selected input port and selected end product port will non contend in farther loops. This procedure is repeated N times or till no cell is available for switching.There is possibility that indiscriminately waiting line can be selected for which there is no HOL cell, under such circum- stances throughput will acquire reduced. Even through switch is con_gured for size of N X N with M queues/port, still we need scheduling policy to run on N _ N matrix. No warrant that throughput is 100 % under heavy tra_c i.e. _ = 1.is 92 4.3 Longest Queue Priority choice ( LQPS ) achieved.Implementation of random choice is di_cult in hardware.No unique solution for same queue length matrix. Following graph shows the throughput public presentation of MIQ with di_erent switch sizes and fluctuation in figure of waiting lines per ports. The throughput is dependent merely on value of M when N is greater than 32.Below N=32 throughput dependant on N and M besides. Figure 4.3: Impregnation Throughput with Random Policy for assorted values of M 4.3 Longest Queue Priority choice ( LQPS ) In this strategy, precedence is given to the longest waiting line FIFO [ 15 ] . In the waiting line length matrix L, Lij = 0 indicates that no HOL cell is available from input port I destined to end product port J. In a cell slot, the algorithm starts with _rst loop where we select a cell from input port I to end product port Js such that Lij is maximal. The cells from input port I and cells destined to end product port J are non considered for choice in all farther loops. From the staying matrix, once more a new maximal component Lij is found. The algorithm terminates after N loops or when no cell is available for choice. In Figure4.4, the circled HOL places are selected cell places. With mention to Fig. 4.4 ( a ) merely three cells are selected even though there is possibility of choosing more than three cells for exchanging. 93 4.4 Weight Maximum Figure 4.4: Longest Queue precedence choice With avaricious attack of maximal queue length choice the packages are selected for exchanging. As shown in Fig.4.4 ( a ) the VOQ A ; apos ; s selected for exchanging are VOQ ( 1,2 ) , VOQ ( 3,1 ) , VOQ ( 4,3 ) , VOQ ( 2,4 ) , where the instantaneous throughput is non 100 % . There are multiple solutions available as shown in Fig. 4.4 ( B ) . Still it is non an optimum solution even though the instantaneous throughput is 100 % . Now see the optimum solution with constrains mentioned earlier which is shown in Fig.4.4 ( degree Celsius ) . The programming policy should be such that it should maximise figure of pack- ets selected i.e. N and at the same clip overall queue length of selected package should besides be maximal to avoid the cell loss.This is discussed in following subdivision on longest waiting line precedence choice with pattern fiting ( LQPSP ) . No warrant that 100 % throughput can be achieved. Multiple solutions are possible. _nding optimum solution is di_cult. there will be fluctuation in throughput if we consider amount of queue length of selected waiting lines is maximal. Algorithm becomes more composite. 4.4 Weight Maximum In the maximal leaden policy, each HOL cell is associated with a weight, Wij. Weight Wij is calculated utilizing Indicator Queue length matrix K as follows. Wij = _XN m=1 [ Kim + Kmj ] _ : Ten _ Kij _ ( 4.1 ) 94 4.4 Weight Maximum Figure 4.5: Impregnation Throughput with Maximum Queue Length for assorted values of M Figure 4.6: Maximum Weighted choice policy ( WMAX ) This weight factor additions with addition in HOL tenancy at input FIFO and hot-spot tra_c to label end product port. In a cell slot, the algorithm starts with _rst loop where we select a cell from input port I to end product port Js such that its weight is maximal in weight matrix W. If the same maximal component is found at multiple places, one of those is selected indiscriminately or round redbreast 95 4.5 RCSUM Minimum policy is used among such input ports. Cells from the earlier selected input port and cells destined for before selected end product port are non selected. This procedure is repeated till N cells are selected or no cell is left for choice. In Fig.4.6 ( a ) , circled HOL place cells are the selected cell places, and the little square indicates loop figure in which matching cell gets selected. In this instance merely two cells are selected for exchanging, these are indicated by circles drawn in Queue length matrix L in Fig.4.6 ( B ) . Merely two cells are selected even though there is possibility of choosing more than two cells. This decrease in figure of cells selected occurs because more figure of cells are deleted from competition at each loop. 4.5 RCSUM Minimum In this strategy weight matrix generated is the same as in instance of WMAX policy. The lone di_erence is that here a non-zero minimal value is searched. If it _nds one such Wij, so cell from matching place is selected for exchanging from input port I to end product port J. If multiple non-zero lower limit values are available so one is selected indiscriminately. Figure 4.7: Minimum Leaden choice policy ( WMIN ) Fig.4.7 ( a ) shows the sequence in which the cells are selected. In Fig. Fig.4.7 ( a ) , circled HOL place cells are the selected cell places, and the little square 96 4.6 Cell choice policies with form fiting indicates loop figure in which matching cell gets selected. Fig.4.7 ( B ) shows the cells selected in Queue length matrix. Fig.4.7 ( degree Celsius ) and Fig.4.7 ( vitamin D ) show another possible sequence of choice of cells. It clearly shows that more figure of cells are acquiring selected here than in WMAX policy. In this strategy, choosing non- zero lower limit from weight matrix will heighten the throughput because in each choice procedure we delete less figure of cells from the competition in the following loop. This is precisely opposite of the WMAX choice standards. This work is published in Canadian Conference on Broadband Research [ 25 ] . But public presentation graph were non presented. 4.6 Cell choice policies with form fiting It is seen that there are 2N2 substitution of forms for choosing cells in the above matrix. However, because of the limitations on cell choice ( in a cell slot merely one cell can be selected from an input and at most one cell can be switched to an end product port ) the figure of forms of the matrix suited for choice for shift is N! if M = N and much less than Nitrogen! for M A ; lt ; N. We constrain the form I of the N _ N matrix such that, XN j=1 Iij = XN i=1 Iij = 1 ( 4.2 ) These forms are substitutions of Identity matrix. Any random form with above limitation can be generated without hive awaying them into the memory. 4.6.1 Generation of forms If we have switch size of N _N so we need ( Noˆˆˆ1 ) ! 2 distinguishable cell places that can be used for exchanging. These generate other allowable permuted forms. Procedure to obtain N! forms is as follows. ( 1 ) Get pattern I and take its image. This will give two forms. ( 2 ) Shift form I right cyclically. Repeating measure ( 1 ) and ( 2 ) N times will bring forth N! forms. If we take N = 4, so we demand three distinguishable forms. To obtain these three form from Indicator matrix, we have to trade column 2 with column 1 and column 1 with column 4. Repeat procedure mentioned above to obtain all 24 ( i.e. 4! ) forms. Fig. 6 shows the procedure of coevals of forms. These forms are favorable forms. These forms are suited for execution by hardware, as they can be generated utilizing parallel hardware. 4.6.2 Longest Queue Priority choice with pattern match- ing We obtain a soap value matrix X by utilizing the relation X = [ Phosphorus ij ( Iij: _ Lij ) ] . Here: _ notation indicates element by element generation. In the illustrated 97 4.6 Cell choice policies with form fiting Figure 4.8: Form Generation illustration of 3 _ 3 matrix, a upper limit of six forms will be available. Therefore, soap value matrix X has six elements. This matrix _nds the lucifer that achieves maximal aggregative weight under the limitations of alone coupling, i.e. select form I such that X = [ Phosphorus ij ( Iij: _ Lij ) ] is maximal and equation ( 1 ) is satis_ed. The column matrix X indicate the value obtained from di_erent forms as shown in ( Fig.4.9 ( a ) ) . Select maximal value from X under the restraint of unique coupling and in bend get the form to be selected for exchanging cells from HOL. In this instance I6 form is selected, ( Fig.4.8 ( a ) ) . In the selected form, 1 indicates that cell has to be selected from input I to end product port J. Once the form is selected so matching cells are deleted from the waiting line. It clearly shows that 3 cells are selected for exchanging. If multiple entries in X have the same maximal value, so take any one form indiscriminately. Round robin precedence may be maintained in choice of forms. This strategy is di_cult to implement in hardware, as it requires ( N2=2 ) _ R spot adder where R is the figure of spots required to stand for length of Queue. It gives better public presentation than LQPS. 98 4.6 Cell choice policies with form fiting Figure 4.9: Longest Queue Priority Selection with form fiting 4.6.3 Random Selection with Pattern Matching In this strategy, the form I with limitations in equation ( 1 ) , is indiscriminately chosen among the N! forms. The logical ANDing of I is done with indica- tor Queue length matrix K. In this strategy, the throughput reduces under non unvarying tra_c and it will be unpredictable. 4.6.4 Maximal Weight with Pattern Matching In this method Indicator Queue length matrix K is considered. The sum weight matrix Z is formed such that Z = [ Phosphorus ij ( Iij: _ Kij ) ] ( Fig.4.10 ( a ) ) . The ma- trix Z indicates weight obtained utilizing Indicator Queue length matrix and form I1 to I6. A maximal value is selected from Z ( hashed elements indicates maxi- silent value ) . If multiple places have the same maximal value one among them is selected indiscriminately. In this instance form I6 and I1 get selected. Fig.4.10 ( B ) shows the place of cells selected from the Queue length matrix. Once the form is selected so matching cells are deleted from the waiting line. The execution of this strategy is easy compared to LQPS with pattern matching.

Pericles and His Influence on Athens free essay sample

Ancient Greece had many ups and downs in its very long history. As a growing civilization, it earned numerous allies as well as enemies. One of these great enemies was the Persians. Although the Persians were very powerful adversaries, the Greeks defeated them and at that point, the era of classical Greece began. The Delian league, which was created to unite all states and protect them from intruders, had turned into an empire. This empire was governed by Athens. As peace and harmony was restored in Greece, the city of Athens was about to experience it’s greatest epoch. A time filled with power and great social and political wealth. All of which was the product of a great man’s work. His name was Pericles. Pericles was born in the year 495 B. C. into a very noble family. He was the nephew of Cleisthenes who founded Athenian Democracy. Pericles lived his whole life in a political environment. We will write a custom essay sample on Pericles and His Influence on Athens or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page When he became involved in Athenian affairs, he received a very good reputation. In 462 B. C. e began to dominate the politics in Athens as a key leader in the democratic movement. Not only was he a great orator, In the history of the ancient Greek civilization, there were many powerful and contributing men and women. Only one could be called the â€Å"Greatest Greek† and that man’s name is Pericles. Pericles was a wise and powerful leader of the city of Athens. He was a great supporter of the concept of democracy. Pericles guided Athens almost through the entire Peloponnesian War. Pericles promoted the arts and literature. This was a main reason Athens held the reputation of being the educational and cultural centre of the ancient Greek world. Pericles rule as a political leader in Athens is called the Golden Age of Pericles, and he was an eager supporter of democracy. He wanted all citizens of Athens to take an active part in politics, and he was the first to pay servants to the state. All Athenians chose members of the council, and Pericles restored and built many temples and structures, such as the Parthenon on the Acropolis, employing the poorest citizens.
