Educational dissatainment on the grounds of sex essays

Educational dissatainment on the grounds of sex essays The results from our observation and from the context analysis of the story clearly support the growing international notion that boys are simply underachieving at school. Whilst many think that boys are achieving no less there is definitely a growth in the gap between the sexes at all levels of education from secondary to primary schooling and possibly even from birth. Ultimately the figures speak for themselves with a noticeable gap being recognized at the age of 7 with girls leading in writing and reading, At 11 the gap then continues with girls out performing boys in all subjects including traditional male topics such as Math and Science. By the time of G.C.S.E results girls are again ahead disproving the idea that boys simply mature later. With girls dominance in traditional male subjects such as C.D.T. as a national survey showed (girls were two thirds better than boys were) and all over the board averaging 8% over the boys at G.C.S.E (Arnot et al, 1996). So what is the future for boys in society, is it possible for them to regain the ground or is it all societies fault? In this explanation we hope to explain some of the sociological theories which have been offered to explain this and ultimately why this gap has grown so suddenly with the help of both named studies and external statistical data. First of all to explain why women are suddenly out striping boys it is important to realise that this may not be a recent phenomenon which has suddenly occurred recently. For many feminists this is the view they have held for some time saying that prior to this growth female students were simply restricted from growing. A change in the female ideology has thus taken place as shown in Sue Sharpes study Just like a Girl in which girls reactions and thoughts on life were recorded in 1976 and later in 1994. From these results she concluded the 1976 pupils were simply worried about ...

Weber or Foucault - Essay Example Through this people in North Korea lack proper knowledge of what is happening. They also do not enjoy the freedom of speech something that has been widely criticized. North Korea has been on the spotlight in the recent for cases of human rights violations. It is impossible to establish the full extent of the violations but the country has been on the spot over different kind of violation affecting human rights according to Paul Walker. It has also been realized that the extent of human rights violation is accelerated by lack of awareness. North Korea’s constitution has been accused on infringing on human rights (Walker). Currently the freedom of speech has been limited to radio stations, televisions and music providers who are legally owned by government or government operated. Moreover, humans have been subjected to forced labor as prisoners in concert ration camps in North Korea.

What specific action(s) should Christians take regarding the Essay - 1

What specific action(s) should Christians take regarding the environment and its preservation or restoration - Essay Example And God said, let us make man in our image, after our likeness; and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over every creeping thing that creepeth upon the Earth† (King James Version Genesis 6:26) One of the priorities that Christians should have within the framework of the way in which they conduct their lives is to be good stewards of the Earth. As good stewards of the Earth it is the responsibility of Christians to make sure that their associations and personal responsibilities are toward an effort to support the creation of the Earth in the manner that God intended. Through looking at the creation story in Genesis, one can clearly see that human kind was given dominion over the Earth. This is further supported in Psalms. However, the concept of dominion often is misunderstood as having the use of the Earth, rather than being held responsible for the way in which the Earth is cared for as a living world. The concept of free will is sometimes considered more the manifestation of God’s will rather than taking responsibility for what has happened to come to terrible outcomes where the Earth is concerned. In looking at the way in which the dominion over the Earth has be en considered, the way in which Christians engage their world should be revised with the attitude that in giving human kind this responsibility, a great trust was handed to human kind. This trust should not be violated by those who believe in Him. When God created the Earth and all of the creations within the realm that is the Earth, the Bible states that man was given dominion over all of His creation. Brown (2011) quotes a portion of Psalms to support the assertion that man was given this power. It states in the Bible that â€Å"You have made him to have dominion over the works of Your hands; You have put all things under his feet† (New King James

A Teacher’s Involvement on Education Reform Essay Example for Free

A Teacher’s Involvement on Education Reform Essay Student achievement is constantly changing. Today’s students are being prepared to face the real world that requires them to have exceeding abilities and knowledge. On the global economic aspect of today, students are asked to understand the fundamentals and at the same time be able to think critically. They must analyze and make inferences. It is the teacher’s task to develop these skills in the students. They must prepare them for any changes in the assessment of the school, especially when this approach is of the large scale and high-stake level. Education in the United States has been reformed countless times – all for various reasons. The changes in the knowledge and skills that are aimed for success go hand in hand with the understanding of how students learn. The relationship between the instruction given in schools and the assessment of the students through exams change the learning goals that are set for them and their schools. Therefore, the need for education reform. 1 Before, society can get by with the basic reading and arithmetic skills. This was during the industrial age. However, we are now in an information age. Individuals are required to have access to the interpretation and analysis of the information that they use in order to come up with decisions. Studies show that the skills and competencies mentioned in the previous sentence are the requirements to succeed in the workplace. 2 To adapt to these changes, the content standards of education – skills, knowledge and behavior of the students – must be achieved at a higher level. This is developed at the national, as well as the state areas of science, mathematics, history and geography. In this process, student assessment is the focus and the center of the efforts on matters concerning educational improvements. The policymakers intend to change the assessment that will allow teachers and schools to have different approaches. Assessment reform is not an excuse for a new regime by teachers. This is targeted to the students with the help of the development efforts of the teachers. These include curriculum reform, improving instruction and getting new instructional materials. A number of policymakers and educators believe that the assessment of the students reflect the lessons that they were taught. It’s true that the assessment influences the format of instruction. Contrary to the understanding of today’s students on how they learn their lessons, the assessments are particularly traditional. Most exams still follow the multiple-choice and the true-false format. These test facts determine the skill in an isolated approach. It seldom requires the students to apply what they really know, making it hard to determine what they are capable of doing in real life situations. The standardized tests do not match the content standards. Relying too much on these kinds of assessment often result to an instruction that only focuses on the basic knowledge and skills. It does not encourage the institution to reform the instruction give to the students. Engaged learning will prepare the students better for the 21st century. That being said, it only makes sense that the tests the students take encourage aggressive learning. 3 The notion that learning comes about by the accretion of little bits is outmoded learning theory. Current models of learning based on cognitive psychology contend that learners gain understanding when they construct their own cognitive maps of the interconnections among concepts and facts. Thus, real learning cannot be spoon-fed, one skill at a time. 4 Educators, policymakers and parents are starting to realize that the basic learning abilities are no longer enough. They need the students to have the skills they learned in school and the abilities they need upon leaving school all at the same time. Schools are expected to assist students in developing these competencies which they will use in real and authentic situations. The establishments are expected to graduate students who have these abilities – students who excel on both the standardized and the alternative assessments. During the last decade, the education community in the United States went through a proliferation of reform efforts that are standardized-driven. Its main objective is to increase the achievement level of the students. They want students from the United States achieve the same level of competitiveness with other industrialized nations. The education community also wants to restore the public confidence in the education. Once these are achieved, then it provides the standards-setting bodies the primary ways on how the classroom teachers can be involved in the reforming process. The federal government is a prominent player in the reforming efforts one educations. It goes all the way back in March 1994 when President Clinton signed the â€Å"Goals 2000: Educate America Act. It was the legislation that created the framework which allowed states to adopt and construct the education reform strategies by incorporating the three Goals principles: 1. ) rigorous academic standards. 2. ) alignment of curriculum, textbooks and teacher education and 3. ) clear incentives to encourage students to strive to meet high standards. Also, in 1987, the National Board for Professional Teaching Standards or the NBPTS was formed in order to articulate the standards of excellence to what teachers must know and should know. NBPTS has an assessment system that determines the eligibility of the educators for the National Board certification. At the same time, the Council of Chief State School Officers has established the Interstate New Teacher Assessment and Support Consortium (INTASC) to produce the model standards for the initial teacher licensure. INTASC standards are based on NBPTS standards. In 1987, the National Council for the Accreditation of Teacher Education (NCATE) started using the revised accreditation standards for teacher education institutions. This also reflects NBPTS standards. It calls for better performance, higher admissions and graduate standards. NCATE encourages the teachers to prepare the reforms on education at a content standard that has appeared from projects such as the NCTMs. There are three kinds of national standards which currently receive attention from the American government. The content standards focus on the curriculum, the performance standards concentrate on the student work and the assessment, and the school delivery standards which centers on the resources and support for the schools, teachers and students. The building figures from the consensus prominently show that the standards- setting movement of the schools and teachers has had de facto standards for the content areas that are mentioned in the Goals. These are affected by the textbook manufactures and the performance standards that are set by the testing companies. In contrast to this, the standards development projects of recent years have tried to get a base of support for a ny academic improvement. The involvement of teacher in the professional standards development can be seen in various areas: 1.  The teachers function as the standards. A lot of members of the NBPTS standards committees are accomplished and celebrated teachers. Classroom teachers are members of the NCATE board and the Standards Committee serve as the team which evaluates the teacher preparation programs. The Standard Project is there to develop the assessment standards. It also serves as the instrument for a national system of voluntary student examination. It engages the teachers in developing the tests items and refining the content standards in order to come up with better scores from the students. 2.  Teachers are the subjects of the fields that are new to test standards. Since they participate in the NBPTS field test, the INTAST assessments are conducted by teachers. 3. Teachers serve as the translators of the content standards. They apply this in a teachable classroom setting. By working with the scholars, the teachers build the contend standards in a state curriculum framework. They come up with lesson plans which are the operations for the standards they intend to meet. 4. Because they bargain units and have professional associations, teachers serve as the initiators of the standards-setting projects.  Take this for example, the Standards for Teacher Competence in Educational Assessment of Students was developed by the American Federation of Teachers, the National Council on Measurement in Education and the National Education Association. 5. Teachers also serve as the critics of the national standards that set the efforts on education reform. The seven model standards that have been developed and supported by the Board of Education have circulated drafts of the standards documents. It also solicits the comment from the teachers and the parents. It is very important that teachers are on the panels in order to oversee the projects. The promotion of students’ critical thinking skills, active engagement in learning and deeper understanding of the subject matter is â€Å"teaching for understanding. † The classroom teachers must be engaged in teaching and understanding the lessons that they teach to the students. The research and the experience are collaborated and are jointly reported. Teachers must also focus on the policy considerations, starting with the perspectives in the classroom and emphasizing on the need for the field-based research that are needed for the multiple contexts of teaching. However, the involvement of teachers also varies on the perception of the school leadership. There are some teachers that perceive the costs of involvement in education reform outweigh the benefits. There are also some teachers who choose to not get involved because it means that this will influence other school policies. With this in mind, this proves that there are two kinds of decisions: the managerial, which is made by the administrators and the technical, which concentrates on the goal. Most teachers prefer being involved in the process than coming up with technical decisions. 7 Then there are some teachers that argue that education reform cannot be imposed on a unilateral approach. Teachers must endorse their new responsibilities and roles, as long as there is a time and enough resources to go about it. Schools depend on the cooperation, relation and interdependence of the staff members that plans such as these must be consistent with the norms that already exist. 8 Schools must also consider the current staff development. There are some models that do not help the teachers in handling the complex reforms that are currently being implemented. Dominant models work perfectly when the specific practices or skills are transferred. The current reforms need teachers to be intellectual. They must grapple the new ways in order to implement the principles and ideas in their daily work. The five steams of reform are challenges to the teachers. 9 Finally, there are the different studies of teachers when it comes to leadership roles. There are conditions that are particularly good prospects when it comes to leadership. By investing in roles that are dignified and not simply powerful, the organizational incentives needed for collaboration results to agreements which protect and separate the interest of the administrators and the teachers. This is a good thing because its final result is that it complies with the policies which support the education reform. Drawing from four different studies of teachers in leadership roles, the author examines the conditions for teacher productivity in schools. Little identifies five conditions as particularly likely to advance or erode the prospects for teacher leadership: define leadership tasks that are important, not trivial; invest leadership roles with dignity, not simply power over others; have organizational incentives for collaboration; avoid agreements that protect the separate interests of teachers and administrators; and have district policies that support teacher leadership, especially those on recruitment, selection, placement, and evaluation of principals. 10 Sometimes it is better to give movie examples. Over the years, there are countless movie releases that show teachers defying the school’s rules in order to provide what is best for their students. In â€Å"Dangerous Minds†, Michelle Pfeiffer encourages her students to read poetry instead of hanging out in the street and ruining their lives by getting involved in drugs, sex and gangsters. In the â€Å"Sister Act 2†, Whoopi Goldberg helms a choir consisting of African American students from the ghettos. Like Pfeiffer in â€Å"Dangerous Minds†, this is the nun’s distraction for the students to make something out of their lives. But a recent movie that depicts educational reform and teacher’s involvement best is the TV movie â€Å"Walkout. † It tells the story of the Mexican-American students in Los Angeles high schools in 1968. They staged a boycott in order to improve the quality of education for Chicanos. Actor-director Edward James Olmos (who plays Jennifer Lopez’ dad in â€Å"Selena) appears and directs in the movie. â€Å"Walkout† was skillfully directed and presented a simple story told in a direct manner. There is a frank portrayal of the unacceptable educational standards in the schools that are attended by the Mexican-American students. In one scene, two Chicano students were slapped on their behinds because they spoke in Spanish. This was only one of the rules in American schools which Mexican-American activists wanted to reform. They want to speak in Spanish whenever they want to because Spanish is their language. For teachers who want a peg in participating in educational reforms, they can look at Sal Castro played by Michael Pena (Jennifer Lopez’ brother in â€Å"Selena. ) He is a dedicated high school history teacher who is the instrument in stirring idealism in his students. He didn’t want them to be violent activists. He encouraged reform but he reminded them that this can be done in a united and peaceful protest. The focal point of the story is Paula Crisostomo (Alexa Vega) who is an exceptional student. She risked her graduation in order to be part of the Lincoln High School walkout. â€Å"Walkout† captures the passion of Paula and her classmates. The parents strongly resisted at the earlier part of the film, but later on they slowly understood the reason behind the activism of their children. The entire cast, played by young performers, is convincing. It is true that â€Å"Walkout† is a film but this is a depiction of something that happened in 1968 which changed history. Because of that walk-out, Mexican-American students are given a voice. The teacher participated in his own way in the education reform his students want granted. Those who watched this movie for the first time were unaware of the Chicano movement of 1968. They were surprised to find out that there was a time Universities kept Chicanos out. Teachers sacrifice their efforts and their time in order to concretize the goals they want for their students. Education reform may not be achieved with just one snap of a finger but that does not mean that teachers should stop trying there and then. For this very reason of reform, teachers and students are more motivated to strive toward success. Education reform is a right that must be made the most out of. It could be better opportunities for the teachers as well as the students. Once the school is presented an option to have an education, then they must seize it. It may be puzzling at first but the absence of education reform can have dire effects on the effective teaching in schools. Research shows that successful schools have reformed their education in relation to the demands of today’s information age. By viewing teaching as the central activity of organizations, more and more educational bodies are encouraging schools to take part of education reform. By proposing the norms, conducts, standards and practices which will serve as the central dialogue and observation of teaching, activities and practices that are related to providing a curriculum and materials needed by the school, students and teachers will be open to the recognition of teacher’s involvement in the whole educational reform process.

The Second Sex by Simone De Beauvoir Essay -- gender differences, 2015

Feminism is the radical notion that women are people. It is the movement for the political, social, and educational equality of women with men. It has its roots in the humanism of the 18th century and the Industrial Revolution. Feminist issues range from access to employment, education, child care, contraception, and abortion, to equality in the workplace, changing family roles, damages for sexual harassment in the workplace, and the need for equal political representation. Some may think that in 2015 we may be completing the first step for women, which has been a long journey, the acceptance of women as people. However, women, like so many other groups, have gained legal rights only to face less institutional, but more subtle forms of discriminations. The idea that women are equal because of women’s rights is in my opinion valid in some ways and invalid in other ways. Traditionally, women have been regarded as inferior to men physically and intellectually. Women could not possess property in their own names, participate in business ventures, or control having children if they wanted them or not or even control of their own lives. The Feminist movement dates from 1848, when Elizabeth Cady Stanton, Lucretia Coffin Mott and others who were at a women’s convention at Seneca Falls, N.Y. issued declaration of independence for women, demanding full legal equality, full educational and commercial opportunity, equal compensation, the right to get paid and the right to vote. In this essay I will discuss The Second Sex by Simone De Beauvoir and her feminist views. I will discuss the gender differences between males and females today as well as in the past. Simone De Beauvoir was born in Paris. She had a younger sister and they lived in middle-class family. She went to a conservative Catholic prep school for girls. She had several licenses, which are equivalent to master’s degrees today, in literature, philosophy and mathematics. While in School she met Sartre a philosopher most closely associated with existentialism. She was one of the first women to pass the rigorous aggregation in philosophy. She taught in Marseiles, Rouen, and Paris from 1931 to 1943, but her contract ended because she was accused of sleeping with a student. After that she began a monthly magazine with Sarte that discussed politics and literature. Simone De Beauvoir’... ... care of the home and their husbands didn’t have a man of her own. Now I don’t know the exact significance of this, but my take on it is that the movie was trying to show that no matter what you do as a woman you can’t make a man stay just because you do what is â€Å"expected†. Overall, feminism aims to have women treat equally as men in all aspects of life. We as women have come a long way since the early 1900s, but really how far have we come? There are still very few women in high positions as me, there still has never been a woman president, and in some cases men are earning higher wages than men even if they hold the same position. However, women have shown that we can do whatever a man can do and we can do it just as good as a man. We no longer have to even consider accepting the fact that we have our â€Å"place† and be seen as the â€Å"object†. Moreover, I think that it is the responsibility of the woman to make sure that she is respected and that she is given the same rights as the man. Also men need to be more aware of the situation that’s occurring. Works cited: The Norton Anthology Theory and Criticism p.1403-1414 www.lib.usc.edu/~retter/1st2.html

Comparing two fictional novels

Telling the difference between two fictional novels is a simple task but finding a similarity within them both is a hard thing to do, or so you may think. When I think of the comparison of the two novels, which I need to pick, there are many books In which I have read before but none as interesting as what I am about to share. One of the books is â€Å"Daughter of the Sea, Hannah† by Kathy Lacks. The other one Is â€Å"The Fallen† by Thomas E. Singsongs. Let us look at the differences between the two novels In the next paragraph.One of the differences Is the thickness of the book and the size of the words. The novel â€Å"Daughter of the Sea, Hannah† Is obviously for smaller kids around five to ten to read as the words are huge and the thickness of the book Is quite thin. Meanwhile â€Å"The Fallen† Is squeezed with tiny little words and Is bounded together In a thick stack. A teenager like me would read one of this. There are even more differences than th ese. The plot of â€Å"Daughter of the sea, Hannah† revolves around an orphan girl as she gradually finds out more about herself as she grows up.She is not like a normal human being but actually something else†¦ The Fallen† is a novel about a teenage boy having odd events happening around him when he later finds out that he is actually the son of a fallen angel. These two novels have not only different kinds of themes but also different kinds of sentence structures. As you know that the novel â€Å"Daughter of the Sea, Hannah† is one for the lower grades to read, it will definitely be filled with simple sentences such as: â€Å"Whatever the creature was, it looked free, utterly free. And â€Å"Hannah could not quite believe it. † These sentences are simple to allow the lower grades to understand the novel better. While, the novel â€Å"The Fallen† as sentences like: â€Å"As intolerable as the voices had become, the sudden lack of them was eq ually extreme. † and â€Å"The door began to slowly open with the high-pitched whine that Tom had been threatening to put oil to since the summer, and three men entered on a powerful gust of wind. † Can you see the differences between them now? † Now, lets move on to the similarities of these two novels.So what makes these two books so different yet so similar? One of it is the plot of these two books. In both stories, the main character is put into hard positions where they have to make decisions that might change they're lives forever. Not only that, both main characters meet new people on their quest and also fall in love. I did not notice they were that similar until I really thought about It. When you read a novel, you do not usually compare the characters with others from another novel.But I noticed that between these two books, both the mall characters are orphans and both have kind, caring and strong characteristics. Whereas for the villain, has a strange, cruel and twisted personality. Every good novel needs a good ending sentence. â€Å"Daughter of the Sea, Hannah† concludes Its story with: â€Å"l am not alone! There Is a world out there. While â€Å"The Fallen† concludes Its novel with: â€Å"By touch he found what was needed, a twelve-Inch blade that glinted sharply In the beams of sunlight that streamed in through openings In the boarded-up windows. The first word that came into my mind was confidence. Why? Because they show me that they what. Something really interesting about the similarities about these two books is that the authors of these two books had me thinking and reflecting to myself. I thought; â€Å"If I were to make an important decision in the future, will I choose the right one? Can I be as strong as them if it goes wrong? Or will I Just snap like a twig and break down? I can see what the authors of these two books was trying to show us and I felt what they wanted me to feel. It's amazing how di fferent these books are and yet how similar they can be. May they be from different genres, for different age groups and with different plots. There will always be a similarity between any two fiction books of any kind. When you compare and contrast two very different books, using you brain and a little bit of you literature knowledge, you will be able to spot the similarities as soon as a strike of lightning.

Gate should be located at country that have less use emphasis in portion and at where decorative non really concern. If we choose a incorrect gate location the merchandise will do low quality and besides the defect will happen on the merchandise. The proper gate location can maximise quality of merchandise besides it can avoid defect to happen.

Redress: a particular cold bullet good accepts cold stuff.Centric location of gate with disconnected passage and rough walls prevent conveyance of cold surface bed. Radius at passage causes laminar flow of thaw into pit and prevent jetting.Table 2.3: Guideline for gate design characteristic. Beginning: How To Make Injection Molds-Menges and Mohren ( 1993 ) The optimal size of gate depend on:Mold temperatureMelt temperatureVolume stuff to be injected into the feelingModeling wall subdivisionThe flow feature of the stuff to be mold.2.4.1Type of gate The chief intent of gate is to link smuggler to model pit during injection procedure. So gate have many type to carry through a different cast to accomplish a good form and quality of merchandise. Basically there are three common type of gate that normally used in injection casting procedure Crawford ( 1998 ) :Sprue gatePin gateSide gate Figure 2.5: Three common type of gate normally used. Beginning: Plastic Engineering by Roy J. Crawford ( 1998 ) 2.4.1.1 sprue gate 2.5Cast Cast can be defined as a portion that act as to determine fictile stuffs. The major map cast to reassign as topographic point that melt plastic will reassign into cast to organize a coveted form and chuck out when thaw plastic bend to solid. Mold consist of nucleus and pit. Basically the pit side is a side that melt plastic will flux to cavity side from nose. Core side maps as defining and besides as expulsion system after melt fictile solidify. 2.5.1Single pit cast Process production of big portion normally differ with little portion in injection casting. Rees and Catoen ( 2006 ) said that big portion are molded utilizing individual pit cast. The production of larger portion are frequently non required in a larger measure. In extra, the building of individual pit cast usage simplest building with a simple injection method and simplest expulsion portion. Figure: Single pit cast.

The value of this parametric quantity will impact the quality of merchandise if non to the full function decently. Harmonizing to Rosato ( 2000 ) incorrect input of parametric quantity puting will take to quality of merchandise bad besides the preciseness will diminish besides will increasing the cost and clip of production. Four type of variables will used in injection casting procedure:The injection force per unit areaThe wadding force per unit areaThe mold temperatureThe thaw temperature2.6.1Injection force per unit area The injection force per unit area is a most of import parametric quantity in successfully present a thaw plastic to whole mould portion. The thaw plastic is force through the nose and present to model infinite. The job during bringing of thaw plastic, the stuff fast cooled if contact with mould surface will traveling and it causes defect if fictile non filled decently with adequate force per unit area. If force per unit area low the thaw plastic non fulfilled mould infinite and high force per unit area besides can do overpacking on merchandise. 2.6.2Packing force per unit area Packing force per unit area is a force per unit area that map to avoid a thaw plastic flow back out of mold infinite during injection modeling procedure. Packing force per unit area besides act as secondary force per unit area phase. 2.6.3Mold temperature Mold temperature is one of of import to see in during injection modeling procedure. Temperature of cast are of import in concluding portion that required surface of merchandise smooth and in good status. If mold temperature low, it will do melt fictile hard to make full besides lead to increasing of injection force per unit area. The cast with higher temperature will cut down emphasis in cast while make fulling procedure and the surface coating will better. 2.6.4Melt temperature Melt temperature known as temperature of fictile stuff to run before injection procedure. A to Higher temperature will do polymer will alter their belongingss. Melt temperature will consequence on the viscousness of thaw plastic that will through mold infinite by bringing system.ParameterValueInjection force per unit area100-130 MPaPacking force per unit areaMold temperature15-65OCMelt temperature230-275OCTable 2.4: Parameter of injection casting for polypropene ( PP ) . ( Beginning: Rees and Catoen-Selecting Injection Molds ( 2006 ) ) 2.7Defect Plastic injection casting is an effectual industry in production of plastic. In industry universe, the merchandise green goods are non in one hundred per centum ( 100 % ) in good quality production. Even in injection casting procedure besides have a same job in quality of merchandise based on defect occurred. 2.7.1Weld line Weld line normally occur during the mold filling procedure when thaw plastic flow in mold form and recombined at terminal of pit or downstream location. The surface of merchandise will look like cleft of the shaped portion and if many weld line exist in merchandise it will considered low quality merchandise. The presence of weld line ever occur in plastic cast production and it will failure the merchandise if used in structural applications due to diminishing strength at weld country. Weld line can split into two ( 2 ) types which is butt dyer's rocket and meld dyer's rocket. Butt weld occurred when thaw plastic going with antonyms way and meet. Other weld line exist when involve extra flow when thaw plastic have recombined in mold pit. This dyer's rocket called meld dyer's rocket. But most normally exist dyer's rocket is butt dyer's rocket because it cause most jobs. Figure: formation of weld line. ( Beginning: Santa Clara University – Engineering Design Center ( 2006 ) ) Gambar butt dyer's rocket and canasta line Harmonizing Malloy ( 2010 ) the weld line exist can be overcome by consider in procedure:Increase thaw and cast temperatureIncrease velocity of injectionIncrease clip and retention force per unit areaMold design must be recheck2.7.2Shrinkage Shrinking occurred during chilling clip. Shrinking happen when thaw plastic flow in cast that indirect contact with cold cast. Harmonizing Beaumont ( 2006 ) shrinking have many job and it may impact the warpage, residue emphasis and portion size. In other words, shrinking is a volume decreases as plastic cools and solidified. Pressure of expulsion to take portion from nucleus of cast will increase because of shrinking because alteration in form or warpage. Figure: Shrinking exist at thick portion lead to warpage job. ( Beginning: Santa Clara University – Engineering Design Center ( 2006 ) ) Malloy ( 2010 ) said shrinking can be avoid by:Keeping force per unit area must high plenty but low plenty to avoid of over packing go on that can take to high degree residue emphasisPreferable gate at thickest subdivision foremost compare to thin because it enable packing at thick subdivision. Thick portion hard to chill and pack because its return longer clip to chillFrom Beaumont ( 2006 ) , the shrinking can be observe by utilizing different type of stuff and it’s for mention intent merely in considered shrinking defect.

Beginning: Beaumont ( 2006 ) 2.7.3Sink grade Sink grade are imperfectnesss of the merchandise that exist during injection procedure. Rees and Catoen ( 2006 ) said that during injection procedure, hot plastic through the thick portion in cold cast wall. The thaw plastic to the wall and solidify foremost while melt plastic fluxing in cast. This causes melt fictile hard to finish fill in pit and causes of bing sink grade. Sink mark expression like a little hole or depressions. Normally appear at intersections of rib and wall or at thickest subdivision. Figure: Sink mark exist on plastic. ( Beginning: hypertext transfer protocol: //www.reblingplastics.com/quality.htm ) The option to get the better of:Increase injection force per unit areaIncrease cast temperatureReduce injection velocityAir trapAfter injection procedure, the thaw plastic will get down excessively solidified in the cast. The air occurred during chilling phase because of air trapped in liquefied plastics. This will make an empty infinite within the portion and consequence the quality of merchandise. The solution to get the better of this job by increased the keeping force per unit area. 2.7.5 warpage 2.8Design of experiment ( DOE ) Mention[ 1 ] DRM Associates, 2007.Injection Moulding Glossary.

Irish Immigration essays

Irish Immigration essays I joined the trip to America with much trepidation. I was barely 16, when my parents decided to move the family to America to seek our fortune. I knew that the trip would not be happy, but became even more nervous when my father Eugene called our trip the American Wake. When I asked him why, he simply said, "Molly, we shall never see Ireland again." Mother just stood by him, watching silently as the ship carried us away from the shore. Like many other Irish during the time, our family moved to America for work, to find a better life. We had been told that America was a welcoming and bountiful country, but this was not always true. I was only 16 the first time I saw a sign that said, "No Irish need apply." I had just arrived in America with my parents and my brother, along with many others of my countrymen from Ireland, England and other parts of northern Europe. My brother Malachy became angry about the sign, since he was young and all he wanted to do was work. But no one would hire him, because of his accent and because his last name was O'Connor ("Irish Immigrants in America But father told him to let it be. Father said we would move somewhere else to begin our new life, somewhere where people would respect us for our hard work, even though we were Irish. The country was just emerging from its own war when we arrived here in 1876. Though the hostilities were officially over, there was still much unrest, particularly in the countryside. In many ways, the situation reminded me of Ireland and the reasons we left. Farmers were reeling from the effects of an economic downturn in the 1870s, which caused the prices of crops to drop. As a result, many farmers around America faced the loss This was a situation we knew well, but there was also an important difference. While the Irish farmers back home faced famine and the loss of their land, the f...

All About Avoir, a French Super Verb

All About Avoir, a French Super Verb Avoir is an irregular French verb that means to have. The multitalented verb avoir is omnipresent in the French written and spoken language and appears in a multitude of idiomatic expressions, thanks to its utility and versatility. It  is one of the  most used  French verbs. In fact, of  the thousands of French verbs, it is among the top 10, which also include:  Ãƒ ªtre, faire, dire, aller, voir, savoir, pouvoir, falloir and pouvoir. The Three Functions of Avoir The many forms of  avoir  are busy binding together the French language in three essential ways: 1) as a frequently used transitive verb with a direct object, 2) as the most common auxiliary verb for the languages compound tenses  and 3) as an impersonal verb in the ubiquitous French expression il y a (there is, there are).   Transitive Verb When used alone, avoir is a transitive verb that  takes a direct object.  Avoir  means to have in most senses, including having something in ones possession and currently experiencing something.  Avoir   can mean to have to, but that expression is more commonly translated by  devoir. Jai deux stylos.   I have two pens.Jai trois frà ¨res.   I have three brothers.Jai mal la tà ªte.   I have a headache.Jai une idà ©e.   I have an idea.Jai à ©tà © eu.   Ive been had (tricked).Ils ont  de largent.  Ã‚  They  have money.On a essayà © de tavoir toute la journà ©e.  Ã‚  We tried to get through to you  all day.Elle a de la famille/des amis dà ®ner.  Ã‚  Ã‚  She has  relatives/friends over for dinner.Elle a beaucoup de sa mà ¨re.  Ã‚  Ã‚  She really takes after her mother. Auxiliary Verb Avoir is by far the most frequently used auxiliary, or helping, verb in French compound tenses, which include a conjugated form of avoir with the past participle of the primary verb. As an auxiliary verb, it is used to build compound tenses, such as  passà © composà ©.  Verbs that dont use avoir, use  Ãƒ ªtre  as their auxiliary verb. For example: Jai dà ©j à ©tudià ©.   I have already studied.Jaurai mangà © avant ton arrivà ©e.   I will have eaten before you arrive.Si javais su, je taurais tà ©là ©phonà ©.   If I had known, I would have called you.Jaurais voulu vous aider.  Ã‚  Ã‚  Id have liked to help you.Il les a jetà ©s dehors. He threw them out.Jai maigri. Ive lost weight.As-tu bien dormi  ? Did you sleep well ?Jai à ©tà © surpris. I was  surprised.Il aurait à ©tà © enchantà ©. He would have been delighted. Impersonal Verb in Il y a One cannot underestimate how essential this function is to the French language, as the equivalent is to English. As an impersonal verb (verbe impersonnel), avoir is the verb in the utilitarian expression il y a. It translates to there is when followed by a singular, and there are when followed by a plural. A few examples: Il y a du soleil.   Its sunny. / The sun is shining.Il y a juste de quoi faire une salade. Theres just enough to make a salad.Il ny a qu lui dire. We just have to tell him.Il y a 40 ans de à §a.  Ã‚   40 years ago.Il y a une heure que jattends.   Ive been waiting for an hour.Il doit y avoir une raison. There must be some reason. A Word About Pronunciation: FORMAL VS. MODERN   Careful with the pronunciation of avoir. Consult an audiobook to hear correct pronunciations. 1. In more formal French, there are many sound liaisons involved with the pronunciation of  avoir: Nous avons   Nous Z-avonsVous avez Vous Z-avezIls/Elles ont Ils Z-ont (silent t) Students often confuse the pronunciation of  ils ont  (aller, Z sound) and  ils sont  (à ªtre, S sound), which is a major mistake. 2. In informal modern French, there are a lot of glidings (elisions). For example,  tu  as  is pronounced  ta. 3. Glidings are in everyday pronunciations of the common expression  il y a: il y a yail ny a pas (de) yapadil y en a yan na IDIOMATIC EXPRESSIONS WITH AVOIR Avoir is used in a number of idiomatic expressions, many of which are translated by the English verb to be.   Jai 30 ans. I am 30 years oldJai soif / faim. I am thirsty / hungry.Jai froid/chaud. Im cold/ hot.avoir ___ ans  Ã‚  to be ___ years oldavoir besoin de   to needavoir envie de   to wantMerci.

Byzantine Constantinople Essay Example | Topics and Well Written Essays - 2500 words

Byzantine Constantinople - Essay Example However, the structures are also indicative of the insecurities felt by the royal family members despite their feelings of need to show status (Mango 39) C. The Basilica cistern considerably reveals political power resting on religiously affiliated personalities, but, that the authority does not render the ruling party immune to the vulnerabilities of the century, in as much as subjugation was the trend. The cistern itself apparently allows unobserved entrance and exit of ruling parties to and from their palace which were eventually turned into huge family mausoleums (Alpaslan 192). D. The architecture is a mixture of a typical Roman design for the famous colonnades and extensive spaces that indicates reputation, and those of the Greeks which are the rolling tendrils of vines with leaves another symbol of power and status. In addition, Christian cross carved on columns can not be mistaken for the influence of religion on the design. A. The Byzantinian church, Hagia Sophia in Istanbul Turkey is lavishly decorated with mosaic of murals of cherubs and holy people who have long gone but was considered as sacred. The edifice was believed to be constructed in AD 532. This was designed by architects Anthemius of Tralles and Isidrous of Miletus. During the Ottoman Empire, the church was converted into an Islamic Mosque. The decorations were all carefully plastered. This was to hide the images as they were a taboo to Islam. But, the plasters were torn off in 1935 to reveal the original images which were grandiose (Jack 75). B. Hagia Sophia was named as Christian Church of Divine Wisdom apparently because of the internal ornaments depicting colorful images of angels and saints constructed under the Roman Emperor who ruled Turkey. But, it was actually a tomb apparently designed for the Emperor and his family's mausoleum. C. The lavishness of Hagia Sophia is a reflection of Roman power in Constantinople. Additionally, authority is coupled to Christian religious affinity. D. The general architecture depicts the complexity of the ideas of the architects in both the interior and exterior part of Hagia Sophia. The posh internal decoration which is a mixture of colors and images represents an abode only meant for royalties. The focal part of the edifice are the vaults right under the biggest dome held by arching pillars and decorated by images of seraphs, saints and flowers in a rainbow of colors. Much similar to what most people usually call as paradise on land. E. Hagia Sophia is a total reflection of a creative mind or minds of people living in the past. It is also an edifice reflective of human desire to dwell in a sanctuary where only beauty exists even after death. 3. The Topkapi palace, Istanbul Turkey A. The Topkapi palace was the imperial palace of the Ottomans in 1465 while the sultans ruled Turkey. As the structure was intended for residence, its size and decorations emits an aura of power. Construction of the huge edifice took place in the 15th century. According to literatures, the palace is actually constructed with varied materials influenced by old structures in Turkey which is mostly of stones. Decorative designs
