The Psychology Behind the Flow State of Mind
The Psychology Behind the Flow State of Mind Happiness Print Flow Can Help You Achieve Goals Understanding the Psychology of Flow By Kendra Cherry facebook twitter Kendra Cherry, MS, is an author, educational consultant, and speaker focused on helping students learn about psychology. Learn about our editorial policy Kendra Cherry Medically reviewed by Medically reviewed by Steven Gans, MD on January 14, 2016 Steven Gans, MD is board-certified in psychiatry and is an active supervisor, teacher, and mentor at Massachusetts General Hospital. Learn about our Medical Review Board Steven Gans, MD Updated on August 08, 2019 Tom Merton /Getty Images More in Self-Improvement Happiness Meditation Stress Management Spirituality Holistic Health Inspiration Brain Health Technology Relationships View All If you ever felt completely immersed in an activity, you might have been experiencing a mental state that psychologists refer to as flow. What exactly is flow? Imagine for a moment that you are running a race. Your attention is focused on the movements of your body, the power of your muscles, the force of your lungs, and the feel of the street beneath your feet. You are living in the moment, utterly absorbed in the present activity. Time seems to fall away. You are tired, but you barely notice. According to positive psychologist Mihály CsÃkszentmihályi, what you are experiencing in that moment is known as flow, a state of complete immersion in an activity. He describes the mental state of flow as being completely involved in an activity for its own sake. The ego falls away. Time flies. Every action, movement, and thought follows inevitably from the previous one, like playing jazz. Your whole being is involved, and youre using your skills to the utmost. Flow experiences can occur in different ways for different people. Some might experience flow while engaging in a sport such as skiing, tennis, soccer, dancing, or running. Others might have such an experience while engaged in an activity such as painting, drawing, or writing. These moments of flow often occur when you are engaged in an activity that you enjoy and in which you are quite skilled. How Does It Feel to Experience Flow? According to CsÃkszentmihályi, there are ten factors that accompany the experience of flow. While many of these components may be present, it is not necessary to experience all of them for flow to occur: Clear goals that, while challenging, are still attainableStrong concentration and focused attentionThe activity is intrinsically rewardingFeelings of serenity; a loss of feelings of self-consciousnessTimelessness; a distorted sense of time; feeling so focused on the present that you lose track of time passingImmediate feedbackKnowing that the task is doable; a balance between skill level and the challenge presentedFeelings of personal control over the situation and the outcomeLack of awareness of physical needsComplete focus on the activity itself How to Achieve Flow So what can you do to increase your chances of achieving flow? In his book, CsÃkszentmihályi explains that flow is likely to occur when an individual is faced with a task that has clear goals that require specific responses. A game of chess is a good example of when a flow state might occur. For the duration of a competition, the player has very specific goals and responses, allowing attention to be focused entirely on the game during the period of play. If you are trying to achieve a state of flow, it can help if: You have a specific goal and plan of actionIt is an activity that you enjoy or are passionate aboutThere is an element of challengeYou are able to stretch your current skill level Flow also happens when a persons skills are fully involved in overcoming a challenge that is just about manageable, so it acts as a magnet for learning new skills and increasing challenges, CsÃkszentmihályi explains. If challenges are too low, one gets back to flow by increasing them. If challenges are too great, one can return to the flow state by learning new skills. Applications and Examples of Flow While flow experiences can happen as part of everyday life, there are also important practical applications in various areas including education, sports, and the workplace. Examples of Flow in Education: CsÃkszentmihályi has suggested that overlearning a skill or concept can help people experience flow. Another critical concept in his theory is the idea of slightly extending oneself beyond ones current ability level. This slight stretching of ones current skills can help the individual experience flow.Examples of Flow in Sports: Just like in educational settings, engaging in a challenging athletic activity that is doable but presents a slight stretching of ones abilities is a good way to achieve flow. Sometimes described by being in the zone, reaching this state of flow allows an athlete to experience a loss of self-consciousness and a sense of complete mastery of the performance.Examples of Flow in the Workplace: Flow can also occur when workers are engaged in tasks where they are able to focus entirely on the project at hand. For example, a writer might experience this while working on a novel or a graphic designer might achieve flow while working o n a website illustration. The Benefits of Flow In addition to making activities more enjoyable, flow also has a number of other advantages. Flow can lead to improved performance. Researchers have found that flow can enhance performance in a wide variety of areas including teaching, learning, athletics, and artistic creativity.Flow can also lead to further learning and skill development. Because the act of achieving flow indicates a substantial mastery of a certain skill, the individual must continually seek new challenges and information in order to maintain this state. A Word From Verywell Achieving a state of flow can be a great way to make the activities you pursue more engaging and enjoyable. Not only do people often perform better when they are in this state of flow, they are often able to improve their skills in that area.

Marriage is another tradition that has been around for as long as anyone can remember. However ââ¬Å"modern divorce patterns date back to 200 years, to the invention of the historically unprecedented idea that marriage s hould be based on love and mutual affectionâ⬠(Coontz, par. 1). Before that marriage would simply be a transaction or deal between families. A deal that could involve the attainment of a physical matter or to continue the family line. That was the purpose of marriage back then. Mutual affection between people was not uncommon at the time.

Evolutionary Biology vs. Creationism Free Essays
Evolutionary Biology vs. Creationism Evolutionary biology and Creationism are both alike and different in many ways. Evolutionary biology is known as an ââ¬Å"interdisciplinary fieldâ⬠. We will write a custom essay sample on Evolutionary Biology vs. Creationism or any similar topic only for you Order Now That is because it is known to include scientists from a wide range of both field and lab oriented disciplines. Evolutionary biology includes scientist who have special training in mammalogy, ornithology, and herpetology. Creationism only has one creator, which is God. God is the one and only scientist and creator of Creationism. Of course evolution plays a major role in both evolutionary biology and creationism. The common definition used for evolution is, ââ¬Å"evolution is the process of change in the inherited traits of a population of organisms from one generation to the next. â⬠One way evolution plays a major role in evolutionary biology is because the many scientists in the fields of evolutionary biology use the organisms from their field to answer general questions of evolution. Evolution plays a major role in creationism because creationism is all about how God created everything such as humanity, the Earth, the sun, and universe. Evolution is how the process of change in the inherited traits of a population of organisms from one generation to the next, and God created everything in creationism, which affected everything from past generations, and still affects change to this generation. In evolution, mutations; which are said to be ââ¬Å"changes to the nucleotide sequence of the genetic material of an organismâ⬠can produce new or altered traits in individuals in genes. A gene is usually defined to be a region of DNA that controls a hereditary characteristic. Natural selection is also known to be, ââ¬Å"a process by which heritable traits that are helpful for survival and reproduction while harmful traits become rarer. â⬠Natural selection usually happens when a person with a more advantage with their traits are more likely to reproduce successfully, so more people in the next generation inherit the traits. I personally believe that without Creationism there would be no such thing as evolution. I believe that there would be nothing without creationism, because as said in the definition; ââ¬Å"Creationism is a religious belief that humanity, life, the earth, and the universe were created by God. â⬠If I had to choose between creationism and evolution, I would definitely choose creationism because like I said before; I believe that there would be nothing if god did not create all of the beautiful things he created.

Emotion and Behaviors free essay sample
This project requires that you observe two preschool-age children in the Child and Family Development Center (ground floor of the Alfred Emery Building) and, on the basis of your observations, report on a particular aspect of their development. In the following pages, three options will be presentedyou may focus on either language development, play, or emotional behavior. Thus, the option you select will determine the nature of the observation you conduct, but it is also true that all projects must follow the same guideline. First, you must decide which of the three options you will pursue. Second, you should become familiar with the objectives of your observation (based on the descriptions presented in the following pages as well as any reading from the textbook that would prove useful in this regard). Third, you should begin planning your observation; this should include decisions regarding what you will focus on during your observations (e. g., behaviors, specific features of the physical and social context), what kinds of things you will try to take notes on in the course of your observation, which preschool class you will observe, and when you will plan to conduct your observation to assure that you will leave yourself enough time for a second chance should you fail to gather all of the necessary information on your first observation attempt. Fourth, you should conduct your observation, paying very careful attention to the behaviors and situations that you have (beforehand! ) decided are most importantin all cases, you will have to observe two children for 15 minutes each. Take notes and remember that these notes are all you will have to work from when writing your paper. I also would recommend that you allow yourself approximately 1 hour for your observation. This would allow you at least a few minutes at the beginning of the observation to get a feel for the classroom and the children in it and to identify the two children you will observe; ample time to observe each child for 15 minutes (which may be split into 5 minutes now, 5 minutes in a short while and 5 more minutes at the end of your hour); and even some time to make up for observations that dont result in any useable information. Fifth, you must rely on your notes and the details of the assignment to prepare your paper. In all cases, I am asking that you provide some general, objective information about what you observed in each child, and that you interpret your observations in terms of what youve learned about preschooler development. In addition, the introduction of your paper should provide a brief description of who you observed, when you observed them and what was going on in the preschool classroom during your observation period. Finally, at the end of your paper, briefly comment upon your experience as an observer. For example, How easy or difficult was it? What did you learn? How confident are you in the representativeness of the behaviors you observed for each child? As usual, all papers MUST BE TYPED. You are limited to 3 typewritten pages so think carefully about how best to organize all of the information you wish to present. Papers are due at the beginning of class on Tuesday, April 15. *****The preschool schedule is as follows: There are three different preschool classes (children ages 3-5): one meets Mon/Wed/Fri, 8:30-11:30, one meets Tues/Thur, 8:30-11:30, and one meets Mon thru Fri, 12:30-3:30 pm). In all cases, there should be no problems if you observe (quietly) from the observation booths attached to each classroom, or from outside the playground fence. If you wish to observe from within the classroom, or if you wish to go onto the playground with the children, you will need the permission of the head teacher. Simply tell them about the project, mention the class and instructors name, and there should not be a problem (do this ahead of time! ). Following are descriptions of the three options, each focusing upon a different feature of preschoolers development. In this exercise, you will be concerned with describing and analyzing the childs speech and determining such things as the depth and variety of his/her vocabulary. 1. It is important to look at the childs speech in terms of Piagets concepts of egocentrism and sociocentrism. Egocentric speech is speech that does not take the other person into account; it is speech that, for all practical purposes, is private. There is no real effort to communicate with the other person; therefore, whatever is said is meaningful only to the speaker. Piaget identified three types of egocentric speech: (a) monologue, in which the individual talks only to himself and with no other persons present; (b) repetition, in which the individual repeats words and phrases over and over again as if to practice them or as if he simply enjoyed making the sounds; and (c) collective monologue, in which two or more persons are talking together but none of them is paying attention to what the others are saying. Each conversation is independent of the other conversation. Socialized speech, on the other hand, is public speech. It is intended to communicate with someone and each person takes into account what others are saying and responds accordingly. Q1: 2. Does the child engage in egocentric or socialized speech? What are the circumstances under which these types of speech are used? Vocabulary is the foundation of speech. We communicate by putting individual words together into properly constructed sentences and paragraphs. Presumably, the greater the number of words in our vocabularies, the greater the number and variety of sentences and ideas we can utter and transmit to others. Words have different meanings and serve different purposes. Moreover, words must be placed in the correct position within a sentence; thus, there are rules of grammar and syntax. Q2: What do you observe about the childs vocabulary? In particular, examine the childs speech for words that express relations and oppositions, for example, words such as and, or, not, same, different, more, less, instead, if, then, and because. Also, how varied or rich is the childs vocabulary when he/she talks about the world and the people/things in it? Think in terms of general classes or categories of objects, persons, and events, then assess how many different words the child uses to discuss those categories and/or how many different categories the child uses. B. Observational Objectives To learn about the language production abilities of preschool children, and how children of preschool age use language as a means of social interaction. C. Procedure For this exercise, your purpose is to observe and record the language behaviors of children as they are engaging in social exchanges. Basically, you will need to write about the vocabularies demonstrated, the ways in which children use their language for the specific purpose of communicating with others (either adults or other children), and the degree to which language appears to be influenced by the setting in which it occurs. For this purpose, select two children and observe each of them for 15 minutes during a time when they have opportunity to interact with others in a small group settingfree-choice periods are probably best. (Do not try to observe two children at the same time! ). As you observe, take notes regarding the nature and variety of words used by each child (writing down exactly what the child says would of course be very useful), the childs specific use of language to communicate with others, and the context in which all of this is going on. For each child, your paper should include a brief description of the language used (including information about vocabulary, communication and context) as well as an interpretation of each childs language behavior in terms of what youve learned about development during the preschool years. II. PRESCHOOLERS PLAY A. Background Information Play is considered by some psychologists to be the most important activity in which the young child engages. Indeed, play activities pervade the lives of children from infancy throughout childhood. Some play seems obviously linked to the childs observation of adults; other play seems to stem from the childs fantasies and from experiences that she finds particularly enjoyable. There are a number of explanations of the major purposes of play. These range from play as getting rid of excess energy to play as a means of socioemotional expression. Play can be a group or an individual activity. Play is distinguished from non-play by its special characteristics, the most important of which are its voluntary nature and its complete structuring by the participants, with little regard for outside regulation. When play is governed by consistent rules, we say children are playing games. These rules give play a social dimension. The participants must put their own personal wishes into the background and abide by the requirements of the game and the wishes of the larger group. It is important to note that not everything children do is play, although they will sometimes try to make play out of what adults intend to be serious. Parten (1932) has identified six types of play, which are given in an accompanying list (next page). Remember that play, like all behavior, occurs in a physical and social context. Therefore, include in your report information on the equipment and materials the child was using in his play and who the child was playing with, if appropriate. B. Partens Six Classifications of Play or Social Interactions 1. Unoccupied Behavior: Here the child is not engaging in any obvious play activity or social interaction. Rather, she watches anything that is of interest at the moment. When there is nothing of interest to watch, the child will play with her own body, move around from place to place, follow the teacher, or stay in one spot and look around the room. 2. Onlooker Behavior: Here the child spends most of her time watching other children play. The child may talk to the playing children, may ask questions or give suggestions, but does not enter into play. The child remains within speaking distance so that what goes on can be seen and heard; this indicates a definite interest in a group of children, unlike the unoccupied child, who shows no interest in any particular group of children, but only a shifting interest in what happens to be exciting at the moment. 3. Solitary Play: This is play activity that is conducted independently of what anyone else is doing. The child plays with toys that differ from those used by other children in the immediate area within speaking distance, and she makes no effort to get closer to them or to speak to them. The child is focused entirely on her own activity and is uninfluenced by other children or their activities. 4. Parallel Play: Here the child is playing close to other children but is still independent of them. The child uses toys that are like the toys being used by the others, but he uses them as he sees fit and is neither influenced by nor tries to influence the others. The chid thus plays beside rather than with the other children. 5. Associative Play: Here the child plays with other children. There is a sharing of play material and equipment; the children may follow each other around; there may be attempts to control who may or may not play in a group, although such control efforts are not strongly asserted. The children engage in similar but not necessarily identical activity, and there is no division of labor or organization of activity or individuals. Each child does what he or she essentially wants to do, without putting the interests of the group first. 6. Cooperative or Organized Supplementary Play: The key word in this category is ââ¬Å"organized. The child plays in a group that is established for a particular purpose: making some material product, gaining some competitive goal, playing formal games. There is a sense of ââ¬Å"we-ness,â⬠whereby one definitely belongs or does not belong to the group. There is also some leadership presentââ¬âone or two members who direct the activity of the others. This therefore requires some division of labor, a taking of different roles by the group members, and the support of one childââ¬â¢s efforts by those of the others. C. Observational Objectives To learn about the distinguishing characteristics of different forms of play, specifically according to Partens classification of play behaviors. D. Procedure Familiarize yourself with Partens classifications of play as described above. Select two children in the preschool and observe each of them for 15 minutes, preferably during a free-choice period when the children are free to move about the room and play with who or what they wish. (Do not attempt to observe both children at the same time! ) As you observe each child, look for examples of each type of play or social interaction as described by Parten. Also, in addition to classifying each childs play behaviors, observe whether there are any patterns to their play. For example, are there particular situations in which a child tends to be an onlooker, but in other situations he/she engages in parallel or cooperative play? As you observe, you should take notes regarding these relevant issues so that you will have something to work from in writing your paper. For each child, your paper should include a brief description of the types of play exhibited (including information about which type(s) are exhibited most frequently) and the social context which characterized each type of play. Additionally, you should provide an interpretation of your observations based on what youve learned about development during the preschool years. III. EMOTION BEHAVIOR A. Background Information Emotions are such a basic part of our psychological beings that we sometimes take them for granted. Some of our emotions are clearly identifiable by us. We know when we are angry, frightened, or joyous. At other times, however, we can have feelings that are not so clear; we may not be able to label what we feel. Whatever the case, emotions are internal experiences that are private and directly accessible only to the individual experiencing them. This being so, we cannot state with certainty what emotion another person is feeling. She must tell us, or we must infer the emotion on the basis of the individuals behavior, facial expressions, and the event that preceded and might have caused the feeling. A childs emotional behaviors become more refined and extensive as she matures. Therefore, a four- or five-year-old will typically be more emotionally expressive than a two-year-old. In this exercise, you will be trying to gain some understanding of the childs emotional behaviors, of the range of her emotions and the kinds of situations that prompt these behaviors. Again, you can only infer what the child is feeling and cannot observe emotions directly. Therefore, be cautious in your interpretations and concentrate on the childs obvious behaviors and the contexts in which they occur. 1. There are several emotions that are commonly found in preschool children: aggression, dependency and fear. Aggressive behavior is frequently defined as behavior that is intended to physically or psychologically hurt another person (or oneself) or to damage or destroy property. An important issue is whether a behavior is intentionally aggressive or simply an accidental occurrence. Further, it is argued by some that in order for a behavior to be termed aggressive, the aggressor must feel anger or hostility toward the victim and must derive satisfaction from hurting the victim. This kind of aggression is called hostile aggression. In contrast to hostile aggression, there can be cases where the aggressor is interested only in getting some object from the victim or achieving some goal. This is called instrumental aggression, and it need not involve anger or hostility. Observe the childs behavior for instances of aggression, either towardà another child or an adult, or towards objects in the environment. Be certain to differentiate between intentional, hostile and instrumental acts of aggression. What kinds of situations or frustrations make the child angry? What behaviors by other people anger the child? How does the child express his/her anger? Dependency consists of such behaviors as clinging or maintaining proximity to adults or other children, seeking approval, recognition, assistance, attention, and reassurance, and striving for affection and support. It is important to recognize that all of us are dependent. The issue is to what degree and under what circumstances we show our dependency. It is also useful to distinguish between two basic types of dependency: a) instrumental dependency, which essentially is the necessary reliance we have on others for certain things that are beyond our capacity to do; and b) emotional dependency, which is a need to be near others and to have their support, affection and reassurance. It can also be the unwillingness or the selfperceived inability to do things for oneself that one can or should be able to do. It is important that, where possible, you distinguish instrumental dependency from emotional dependency behaviors. It is also important to note that as children mature, the characteristics of their dependency behaviors change. Very young children are likely to show clinging and proximity-seeking behaviors, whereas older children, who also have greater cognitive abilities, will likely seek attention and approval. Q3: 3. Fear is demonstrated by such behaviors as crying, withdrawing, seeking help, and avoiding the fear-producing situation. Fear can promote both dependency and aggressive behaviors. Nonetheless, fear can be expressed in such a way that it, and not aggression or dependency, is the primary emotion. Q4: 4. In what situations or activities is the child dependent, and, for example, seeks the presence, direction, or assistance of others? In what situations is the child independent and does not seek direction or assistance from others? What kinds of objects or situations appear to scare the child? In what ways does the child express his/her fears? How does he/she deal with his fears (e. g. , by withdrawing, confronting the fearful situation, seeking help)? In addition to the emotional behaviors just discussed, there are other feelings that children are capable of experiencing and expressing. You should be alert to as many of the childs affective states as possible. For example, there are the feelings of pleasure and displeasure, frustration, boredom and sadness. Like adults, children will differ as to how accurately they can identify and/or express what they feel. Q5: What kinds of things does the child find pleasant? What activities, play materials, stories, games and so on, seem to be particularly attractive to the child? How does the child express that pleasure? Q6: What kinds of things are unpleasant or uncomfortable for the child? In what situations does the child appear to be ill at ease? How does she express her displeasure? Q7: Are all or most of the childs feelings expressed with equal strength, or does their intensity vary with the particular feeling or situation? B. Observational Objectives To learn about the differences in childrens emotional behaviors and the range of emotional responses in preschool children. C. Procedure Select two children, observe and record each childs behavior for a 15-minute period (do not attempt to observe both children at the same time! ). Record behaviors in as much detail as possible (attending to the kinds of things that would help you answer the above questions) and be sure to include descriptions of the physical and social context as they apply to the emotional behaviors observed. IT IS RECOMMENDED THAT YOU OBSERVE CHILDREN DURING THE VERY BEGINNING OF THEIR PRESCHOOL CLASS SO THAT YOU WILL BE ABLE TO SEE THEM AS THEY ARE BEING DROPPED OFF BY THEIR PARENTS AND THEN MAKING THEIR INITIAL ADJUSTMENT TO THEIR PRESCHOOL SETTING. Your paper should include a brief description of each childs behavior (including the different kinds of emotions, the contexts in which they occurred and the relative frequency of each expression) as well as an interpretation or comment on each child using some of the questions and background information provided above. Finally, compare the two children, looking at the range of emotional expression, intensity of expression, and what evokes the emotional responses. In short, summarize how the children differ from each other in this area of functioning.

Absolute Values In Radicals Essays - Elementary Arithmetic, Algebra
Absolute Values In Radicals Absolute Values in Radicals Absolute values in radicals is a very easy concept, once it is mastered. Basically an absolute value is the positive square root of the sum of the squares of the real and imaginary parts of a complex number. An absolute value sign is two straight lines that are place around the exponent to show that the value of the exponent is a positive number. Absolute value signs are needed when there is an even exponent inside a radical and when the square is taken the exponent becomes odd. Then, the odd exponent is placed outside the radical and absolute values signs are placed around it. Absolute value signs are needed because the exponent could be a positive or a negative number. X could be negative number and if it were raised to an even power, it would become positive. But if someone would need to find the square root, the absolute value signs would be needed to show that could be a nonnegative value.

Sculpture Overview â⬠Art Notes (200 Level Couse)
Sculpture Overview ââ¬â Art Notes (200 Level Couse) Free Online Research Papers Sculpture Overview Art Notes(200 Level Couse) At is always a transformation of reality, never a duplication Sculpture, along with painting and architecture, is usually, but not very usefully, classified as on of the visual arts. Most sculpture, whether abstract or representational, returns us to the voluminosity (bulk), density (mass), and tactile quality of things. The primary subject matter of most abstract sculpture is the density of sensa The space around a sculpture is sensory rather than empty Sculpture and Density Sculpture occupies space as a three-dimensional mass, whereas paining is essentially a two dimensional surface that can only represent (ââ¬Å"re-presentâ⬠) three-dimensionality Painting may suggest density whereas sculpture is dense We can only fully apprehend sculpture by senses that are not only alive to visual and tactile (touchable) surfaces but also to the weight and volume lying behind those surfaces Sculpture and Painting Compared The distinction between abstract and representational sculpture is worth making, just as with painting, for being clear about the subject matter of a work of art is essential to all sensitive participation. It is the key to understanding the content, for the content is the subject matter interpreted by means of the form. Sensory Interconnections The sensa of touch, for instance, are normally joined with other sensa ââ¬â visual, aural, oral, and olfactory. Even if only one kind of sensum initiates a perception, a chain reaction triggers off other sensations, either by sensory motor connections or by memory associations Surface-Relief Sculpture There are some clearly noticeable projections out into space, but almost every device available for creating the illusion rather than the actuality of spatial depth ââ¬â foreshortening, landscape vistas, perspective effects, etc. ââ¬â is used. Sunken-Relief Sculpture Has grooves or lines cut into the surface while the surface remains clearly perceptible Usually carved This work, when you stand before it much more than when you see it in a photograph, has significant tactile appeal High-Relief Sculpture A term used in sculpture for figures in wood, stone, marble, etc., so cut as to project at least one-half from the tablet. Has a front or back and can be hung on a wall Low-Relief Sculpture Relief sculpture projects relatively slightly from a background plane such as a wall or column It projects relatively slightly from its background plane, and so its depth dimension is very limited Sculpture in the Round Sculpture meant to be viewed from any side. Any sculpture that can be walked around When the human body is portrayed in the round, we may have the most vivid material counterpoint of our internal feelings and mental images of our bodily existence. All sculpture always evokes our outward sensations and sometimes our inward sensations. Sculpture in the round that has as its subject matter the human body not only often evokes our inward sensations but also interprets them Space Sculpture Emphasizes spatial relationships and tends to de-emphasize the density and materiality of its materials Usually made by assembling preformed pieces of material Usually abstract sculptures ââ¬Å"Truth to Materialsâ⬠A carving from wood, shaped so as to reveal the grains of the wood ââ¬Å"Ready ââ¬â Madeâ⬠Sculpture A man-made object used as a major part or totality of the sculpture Earth Sculpture A design that uses the earth as the base for the sculpture Machine Sculpture A kinetic or moving work energized by a machine Idealized Sculpture A natural figure made more beautiful Sculpture and Architecture Compared Architecture is the art of separating inner from outer space in such a way that the inner space can be used for practical purposes.

High Dropout Rates in the United Sates Research Paper
High Dropout Rates in the United Sates - Research Paper Example In the recent years, California schools in the United States have registered high rates of dropout particularly among African-Americans. As result of many factors, this has raised the concerns of many of the parties involved in the education sector. These parties include government agencies departments, and the non- governmental organizations. The revelation of the high dropouts in schools has led to a research being carried out through cooperation and collaboration of the various agencies to investigate the trends, reasons behind this problem and how this can be curbed and reduced. Government has instituted a four year research to study the trends of the high dropout rates, establish the reasons behind the trend, investigate the efforts to reverse the trend, and come up with amicable recommendations to solve this problem. According to previously carried out research, there is difference in the rates of dropouts among the various races. Race distribution in any Californian school determines the rate of drop out the school will experience over time. High dropout rates are recorded among the minorities with African-American recording the highest rates. Whites and Asians have in the past recorded the lowest rates of dropout from schools. This is because of reasons associated with the background of the students, parental expectations, and faculty expectations. The expectations held of the student by the society at large either demoralize or motivate the students in pursuit of their education.

Race as a factor in the evaluation of the admissions process Case Study
Race as a factor in the evaluation of the admissions process - Case Study Example Race as a factor in the evaluation of the admissionsââ¬â¢ process The moral defense of a universityââ¬â¢s practice to incorporate race as a factor in the evaluation of the admissionsââ¬â¢ process can be examined through the application of diversity and diversity compensation arguments. The presence of obvious group disadvantage which is experienced by members of a certain race would imply that the consideration of race as a factor in admissions is conducive to the reduction of the racial groupsââ¬â¢ social limitations while, eliminating the aspects of historical discrimination, the prejudiced mindset of mass media, educational, occupational and residential segregation and the negative impact of the cycle of poverty. The accumulation of this aspect promotes the emergence of individual disadvantages which translates into group disadvantage. For example, research on career opportunities and housing arrangements for racial groups indicates that discrimination and stereotyping is prevalent. The presence of these elements adversely affects the ability of minority students and harms their potential for further development. Through the application of the concepts of aforementioned arguments it can be concluded that race can be justified as an element of consideration in the holistic admissions process which evaluates the individual candidateââ¬â¢s abilities beyond the traditional measures of admissions criteria and takes into account the significance of their life experiences.

Networking And Routing Protocols
Networking And Routing Protocols At present, internet plays a vital role in many of our daily life. It made a dramatic revolution on communication which we enjoy today. The revolution offered web appliances, e-commerce, video conferences, online gaming and so on. All these became possible and operating on the backbone called networks. On the first hand, before discussing about routing and routing protocols well go through and networking. Initially U.S. government funded researches on sharing information within computers for scientific and military[1] purposes. Though there were many contributed to the foundation of internet J. C. R. Licklider was the first among them. As a leader of Information Processing Technology Office (IPTO) he demonstrated the concept of time sharing and promoted the researches and concepts on networking. Time sharing made a major evolution in the IT world. It became the basis for networking as well. Licks successors as leaders of IPTO, Ivan Sutherland and Bob Taylor influenced by Intergalactic Network lead the researches of Advanced Research Projects Agency (ARPA)s IPTO. The three people Paul Baran, Leonard Kleinrock and Donald Davies developed fundamentals for ARPANET with their own concepts such as packet switching and so on. After continuous researches on implementation of networks, the first ARPANET interconnected and became success in 1969. Being limited for military and research purposes by universities ARPANET has gone through several modifications and adopted many mechanisms. By 1990 networks gradually became for public and from their several other technologies emerged based on networks. When the networks used by general public, it began to grow massive and more complex. So there was a need for a man in the middle kind of device to handle the routes for networks. So that experts coined the device called router. Router is a networking device used to forward the data to an interface to route the data towards its destination. Again the network administrator had to do a hectic job of adding static routes and updating each and every route in a network. For instance, if a link goes down all the routers should be updated manually to cope with it. So to handle these messy situations experts came up with the routing protocols. Though there were plenty of contributors and technology shifts in various occasions in the industry, the above paragraphs covers the milestones in the history. Routing Concept Routing is the process of directing a packet towards the destination with the help of router. The router receives a packet from one interface, determine which interface to be forwarded based on routing algorithm and destination address and then send the packet to the interface. To route a packet the router should satisfy at least following, Router should know Destination address subnet mask Discover Neighbor routers where it can identify the routes for remote routers Identify all possible routes for all remote networks The best path for routing the packet The process of maintaining and verifying the routing table and routing information In general, routing can be categorized as static and dynamic routing. Static routing is the process of adding the routes manually in the router table. The Static routes have the administrative distance of 1 by default. IP route 172.16.30.0 255.255.255.0 172.16.20.2 Dest n/w subnet mask next hope Static routing has no overhead on router CPU or bandwidth of the link and secure compared to dynamic routing. However, static routing doesnt have fault tolerant and its a tedious job to add routes manually. In a wide area network, adding all the routes is definitely a hardest job. Then again when a topology changes or a link goes down again the network administrator have to run all over the place to update. However in some scenarios, static routing remains handy. For instance, in stub networks where all the traffic routed towards a gateway static routing is inevitable with default routes. So static routing consume less resources, easy to configure, more secure and can handle multiple networks. Default routing is a category of static routing where only the exiting interface is specified. IP route 0.0.0.0 0.0.0.0 serial1 Dest n/w Subnet Exit interface Administrative distance for default routing is 0. Default routing is used to send packets to remote networks when the router doesnt have information about it on routing table. The next crucial, widely used category is dynamic routing which is concerned in this project. Dynamic routing is the process of keeping the routing table up to date with instant updates from routing protocols. These protocols dynamically share the information and able to update the routing table when topology changes occur. Further, these protocols determine the best path based on metric calculations. So that dynamic routing protocols remain crucial in large scale corporate networks to update their routing tables. Dynamic routing protocols provide fault tolerance by broadcasting updates when links goes down or server shutdown. To update the router tables the routing protocols define the rules for communicating with the neighbor routers. The rules specify the method and algorithm to exchange information between neighbors. All in all though dynamic protocols consume more CPU power and bandwidth when compared, they are robust and more reliable in networks, especially large scale. Routin g protocols can be categorized in various ways based on their characteristics. Initially, protocols can be divided into routing and routed protocols. Routed protocols are responsible for actual data transfer. The protocols under this category are TCP/IP, IPX/SPX, and apple talk. Routing protocols exchange the routing information between routers. They include RIP, RIP v.2, IGRP, EIGRP, OSPF BGP and so on. Further dynamic protocols can be classified as, Interior gateway protocols (IGP) and Exterior gateway protocol(EGP) Class-full and Class-less Distance vector ,Link-state and hybrid protocols IGP and EGP are characterized based on autonomous system. Autonomous system (AS) is the collection of networks within one administrative domain. IGP protocols are used to exchange router information between same AS number and EGP is between different AS numbers. Rip, Rip v.2, IGRP, EGRP, OSPF, IS-IS come under IGP and BGP is under EGP. Class-full routing protocols do not advertise the subnet mask but class-full address in advertisement. Class-less protocols advertise subnet mask. RIP and IGRP are class-full and RIP v.2 EIGRP, OSPF and IS-IS are classless. The other important characterization is Distance vector, Link state and hybrid. Distance vector protocols Advertise periodically Advertise full routing table Advertise only for directly connected routers High convergence time Limited no of hops Suffer from routing loop Do not establish neighbor relationship Protocols RIP, IGRP Link state protocols Advertise only when network triggered Advertise only the update Flood the advertisement Convergence is low No limits in hop count and suitable for large network No routing loops Establish neighbor relation in formal way Protocols OSPF IS-IS Hybrid protocols Its a combination of both Distance vector and Link-state. EIGRP share such routing characteristics. Dynamic routing Protocols Routing Information Protocol (RIPv1) Routing information protocol version 1 known as RIP is the initial routing protocol to be implemented in ARPANET in 1967. As classified before RIP is a class-full, distance vector and interior gateway protocol (IGP). RIP was developed based on Bellman-Ford algorithm and use hop count as the metric value. It uses the lowest hop count to calculate the best path. Rip limits the number of hosts it supports in a network to prevent routing loops and maintain stability. It supports a maximum of 15 hops in a network. 16th hop is defined as in infinite administrative distance and they become unreachable and un-shareable. It uses broadcast address 255.255.255.255 to send updates between routers. Administrative distance for RIP is 120. Rip use several timers in the advertising and updating process. Routing update timer, route timeout timer, and route flush timer are the timers used by RIP. Routing update timer is used to determine the time interval between each update from rip implemented router. Usually a full update is sent every 30 seconds from router. This became a problem when all the routers simultaneously try to send updates every 30 seconds and consuming the bandwidth since they are synchronized. So that when the timer is reset random time is added in addition to the 30 seconds to prevent such congestion. Route timeout timer is the time frame until a record remains valid before it gets an update with same record. If the router doesnt get the update again within the time frame router marks the record for deletion and hold it until the flush time expire. After the flush time expires the record will be purged permanently from the table. Rip protocol preserve stability by limiting the number of hops to prohibit routing loops propagation. RIP implements split horizon, route poisoning and timing mechanisms to prevent erroneous information propagation. However, limitation on number of hops becomes a setback in large scale networks. Limiting only to class-full advertising is another drawback in RIP. Further, routing updates are not capable for authentication process which is a security concern with version1. Despite rip being emerged ages ago it still exists in routers. Because it is easy to configure, stable, suits well for stub networks and widely used. Routing Information Protocol (RIPV2) Rip version 2 was standardized and released in 1993 due to lack of some important features in version 1 as mentioned above. Version 2 is an enhancement for variable length subnet masking (VLSM). Ripv2 designed to support classless routing with subnet masks which was a critical update from earlier version. Version2 updates carry more information with simple authentication enabled on it. It uses multicast address 224.0.0.9 to send updates. Multicasting avoids the hosts which are not part of routing from receiving update. This version also maintains the maximum number of hops to 15. Open Shortest Path First (OSPF) Routing Protocol Open shortest past first (OSPF) plays a key role in IP networks for several reasons. It was drafted to be used with the internet protocol suite with high functionality as a non proprietary protocol. OSPF is an interior gateway routing protocol which routes packets between the same autonomous systems. It has an administrative distance of 110. It is designed to fully support VLSM (Variable Length Subnet Masking) or CIDR (Classless Inter-Domain Routing).Also it supports for manual summarized advertisement. Its a link state protocol. So it scales well[2], converges quickly and offer loop free routing. On a topology change or link down it converges quick enough to provide a new loop free route. It uses cost to calculate the metric value. The shortest path is calculated based on Dijkstra algorithm to find the best path. OSPF use multicast addresses for updates. The addresses are, 224.0.0.5 is for sending updates and 224.0.0.6 is to receive updates. OSPF maintains three types of tables namely, routing table, neighbor table and database table. It uses Hello protocol to establish neighbor relation and maintain a neighbor table. Hello protocols attributes are, Router ID Priority (default 1) Hello interval (10 sec) Dead interval (40 sec) Authentication bit Stub area flag Process ID The relationship is established based on the router ID. To establish a neighbor relationship timers (hello dead), network mask, area ID and authentication password should be same. It uses area to communicate among routers. OSPF can be configured as single area or multi-area network. Areas are introduced to constrain the flooding of update into a single area. An OSPF domain is split into areas and labeled with 32 bit identifiers to limit the updates and calculation of best path with Dijkstra algorithm into one area. Areas should be carefully designed and configured to group the hosts and routers to a logical area. Each area maintains its own link state database which is distributed via a connecting router to other networks. Such design reduces the traffic flow between areas and keeps the topology anonymous to other areas. In single area OSPF the entire interface in that network belongs to same network. The diagram below explains a configuration in single area OSPF. In multi-area, all other areas must connect to the back bone area (area 0) directly or virtually. The diagram below is a sample of multi-area configuration. A multiple area OSPF must contain at least one backbone / zero area and may have several non-backbones. Zero area remains as the core area for all the other areas. All the other areas connect to backbone area to get updated. OSPF allows configuring stub networks as well. In OSPF stub networks external updates are not flooded in to the stub area. This will result in reducing the size of database size and thereby memory consumption. When stub network area is configured default routing will be used to connect to the external areas. OSPF defines the following router states, Area border router (ABR) Autonomous system boundary router (ASBR) Internal router (IR) Backbone router (BR) The routers could play one or more roles as mentioned above in an OSPF network. The router identifier should be defined in a dotted decimal format to associate each OSPF instance with an ID. If it is not explicitly specified, the highest logical IP will be assigned as the router ID. Area border router (ABR) is the common router which placed on the edge of the backbone area to connect other areas via its interfaces. The ABR keeps a copy of the link state databases of both the backbone and of the areas which it is connected to in its memory. Autonomous system boundary router (ASBR) is the router which connects an autonomous system and a non-OSPF network. ASBR remains as a gateway to connect an AS to other routing protocol networks such as EIGRP, RIP, BGP, static and so on. It also used to exchange routes which it learned from other AS number through its own AS number. The router which has all its interfaces and neighbor relationship within an area is called as Internal Router (IR). All the routers which are part of the backbone area are backbone router (BR). It may be a backbone internal router or an area border router. ABR is also a BR since it is connected to backbone via a physical or logical link. From OSPF configurations the routers elect designated router (DR) and backup designated router (BDR). A designated router (DR) is elected on a multi-access network segment to exchange routing information with other routers. The job of the DR is multicasting the router update which it received to the other routers. So other routers listen only to the DR instead of listening to broadcast. DR elected to act as one-to-many instead of many-to-many routing update. So updates are sent only to the DR router and it updates all the routers within the segment. This election mechanism reduces the network traffic a lot. The router with the highest priority among the routers will be elected as the Designated Router. If more than one router has same priority Router ID will be used as the tie breaker. In multi access networks Backup designated router (BDR) must be elected next. BDR is a standby router for DR if DR becomes unavailable. The router which becomes the second in the election process will be the BDR. If both become unavailable the election process will be held again. The BDR receives updates from adjacent routers but doesnt multicast them. OSPF adjacency is established to share the routing updates directly to each other. Establishing adjacency depends on the OSPF configuration in routers. From OSPF configuration point of view networks can be categorized as, Broadcast multi-access In broadcast multi-access networks routers have direct access to all the routers via direct links. Some of the examples for Broadcast multi-access are Ethernet, and Token ring. Through Ethernet multiple devices are allowed to access the same network. So when an OSPF packet is sent on the network itll be broadcasted and all the routers will receive it. With OSPF DR and BDR should be elected for broadcast multi-access network. Non-broadcast Multi Access (NBMA) NBMA network allows data transmission over a virtual link or across a switching device between the hosts in the network. Typical examples for NBMA are X.25, ATM and Frame relay. In NBMA, all the devices are connected through a shared medium. It doesnt support broadcast or multicast. Instead, OSPF sends the hello packet to each router in the network one at a time. As a result OSPF should be configured specially and the neighbor relationship should be specified properly. Power Line Communication (PLC) is also categorized as Non-broadcast Multiple Access network. Point-to-point In Point-to-point connections, both routers endpoints are connected point to point to provide a single path for communication. High-Level Data Link Control (HDLC) and Point-to-Point Protocol (PPP) could be the examples for P2P. In point to point network, it may be a serial cable connecting the endpoints directly or a virtual link which connects two routers apart in greater distance. But both scenarios eliminate the need for election of DR and BDR in OSPF implementation. The neighbors will be identified automatically with P2P. Point-to-multipoint Point-to-multipoint topology refers to connecting a single interface of a router to multiple destination routers. All the devices in Point-to-multipoint will be in a same network. Conventionally the routers could identify their neighbors automatically in broadcast network. Enhanced Interior Gateway Routing Protocol (EIGRP) Enhanced Interior Gateway Routing Protocol (EIGRP) is a proprietary, hybrid protocol owned by Cisco. It was developed by CISCO as a successor of IGRP. Though its not a version of IGRP; its completely different. It behaves as both link state and distance vector protocol. Its a classless protocol as well. Administrative distance for EIGRP is 90. It exercises a different algorithm from previous protocols which is known as Diffusing update algorithm (DUAL). DUAL algorithm ensures to find the best path with faster convergence and loop free routing. EIGRP supports unequal cost balancing as well. It uses multicast address 224.0.0.0 to send updates. EIGRP also use autonomous system number. It maintains three types of tables, Neighbor table maintains data about the neighboring routers which are directly connected and accessible. Hello packets with timers are employed to keep the record with precision. Topology table The topology table contains all the destinations advertised by its neighbor routers. It maintains the table as an aggregation of all advertised routes with adjoining metrics. In addition from the aggregation a successor and feasible successor will be identified and stored. The successor path is the best path to reach a destination based on the least sum of advertised distance from a neighbor and the distance to reach that neighbor. This route will be installed in the router. The optional feasible successor has the metric higher than successor, which qualify to be the next successor. This route doesnt get installed but kept in the topology table as an alternative. The router will automatically add the feasible route as successor when the successor becomes unavailable. The state of a route for destination can be marked as active or passive in the table. When the router find successor unavailable with no backup routes it query the neighbor routers. This state is called a s active and when it gets a reply it changes to passive state. This whole process ensures a loop free path for destinations. Routing table This table store the actual routes for all destinations. This table is build from the previous topology table calculation. A successor route and an optional feasible route will be stored in this table. Network Modelling Basically Network modelling is a main concept of network deployment into network planning, designing and implementation. Modelling is used to describe concept of the project. Network analysis and network designing should be defined before create network modelling. Define the requirements, objectives and problem areas should be created in network analysis part. So at this stage describe about the router and routing concept towards how they are using routing protocol to route the packets and how to configure with those routing protocols. After this stage implementation part considers all fulfil requirements. Finally design part where we define appropriate network deployment. Network modelling is giving a lot of helps to think more ideas to create best possible network model. Because of that I selected OPNET simulator in this project to create network models. OPNET Modeller 15.0 (Optimized Network Engineering Tools) Currently OPNET is one of the best tools among many network modelling tools in the network technologies. It provides us to designing network model using all kind of network equipments. Networking designers are gained better understanding of designing before development process. It helps to reduce time manner and expense of prototyping hardware equipments. We can able to analyse, measure the performance and behaviour of proposed Model system from event simulations. OPNET tool contains many features. There are main three editors in the OPNET ̉́" Project Editor: It contains graphical interface of network topology nodes such as subnet, hub, switch, router, etc and much kind of links to communicate among those devices. All are designed with graphical user interface such as easy to end users. ̉́" Node Editor: It is describe clear picture of internal architecture of the nodes by investigate the data flow between useful nodes. Node model can send, receive and create network traffic with other node model through the packets. ̉́" Process Editor: It describes about the processes and events create by implementation of specific process operation on the network such as behaviour and functionality of the node model. During the simulation time each node model may create a process of any event, so that it gives the state of process and its functionality. Completely we cant compare simulated network with real world time traffic. But it will give some of information such as how much required bandwidth, where the jamming can occur and how to handle to avoid these problems.

Invisible Man Essay: Invisible Man and the Pre-Made Identity
Invisible Man and the Pre-Made Identity à Society forms definitions, or stereotypes, of people according to the color of their skin, their economic status, or where they live. Stereotypes define how society believes these people should act and how they should be treated. These stereotypes are, in effect, a pre-made identity. There are three options an individual must face when presented with this pre-made identity. The individual can accept this identity as his/her own. This would maximize the individuals acceptance into society, but at a considerable price. The individual would lose power, become exploitable, suppress and consequently lose his/her own "true identity," and then would become one of many faces in the crowd. The "true identity" would be stifled and strangled under the one imposed by society. Anger, frustration , and confusion would occupy the mind of the individual. The individual could reject this identity outright and could circumvent the accumulation of this anger and confusion, but not without consequences. This person may be branded a heretic and be rejected by society. They would lose their agency and legitimacy in the society and would lose any hopes of bringing about any change. The third option entails living a lie. On the surface the individual would embrace society's identity, bu t keep their true self hidden within. This option would allow the person to retain their agency in the society and their individuality. However, like the other two options, there exists a downside. The person would constantly have to put on the mask a particular community wants him/her to wear in order to conform to that community's ideals. It then becomes almost impossible for anyone to get to know the real person, hid... ...come invisible.à à Works Cited and Consulted Bellow, Saul.

Capital Budgeting Essay
Introduction The purpose of this paper is to analyze and interpret the answers of the Capital Budgeting Case. I will discuss my recommendation about which Corporation and investor should acquire based on the quantitative reasoning. I also will describe the relationship between the net present value and the internal rate of return for the two corporations that are analyzed. Capital Budgeting Case A company is planning in acquiring a new corporation and there are two options with the same cost of $250,000 but both with different 5-year projections of cash flows. The evaluation done to the two corporations (A and B) is based on the Net Present Value (NPV) and the Internal Rate of Return (IRR). The net present value represents the value the project or investment adds to the investor wealth. The NPV method of capital budgeting suggests that all projects that have positive NPV should be accepted because they would add value to the investment. On the other hand, the internal rate of return is defined as the discount rate that equates the present value of a projectââ¬â¢s cash inflows to its outflows. According to the internal rate of return method of capital budgeting, the investment should be accepted if their IRR is greater than the cost of capital. The results for Corporation ââ¬Å"Aâ⬠shows a NPV of $20,979.20 based on discount rate of 10%. And, we got an IRR of 13.05% which means that is the discount rate that makes the NPV equal or close to $0.00. On the other hand, the Corporation ââ¬Å"Bâ⬠with a discount rate of 11% got a NPV of $40,251.47 and an IRR of 16.94%. A positive NPV is considered a good project, and we want to choose the one with the highest NPV. Therefore, I would recommend acquiring the Company ââ¬Å"Bâ⬠because it has a higher NPV than the other company. Corporation B will be giving us a current value cash return of $40,251.47 above our 11% required rate of return during the next 5 years. And, if we recalculate the NPV using the IRR of 16.94% it will result on an NPV close to $0.00. The relationship between NPV and IRR is based on the discount rate used to bring up the cash flows to the present. For the case of Company ââ¬Å"Bâ⬠, with the discount rate of 11%, if we have a NPV of $0.00, our IRR will also be 11%. But, if our NPV is higher than $0.00, our IRR will be also higher than 11%. And, if we have a negative NPV, then our IRR will be less than 11%. In other words, the NPV and the IRR most of the time yield the same result of acceptance or rejection. Conclusion In conclusion, the best recommendation is to acquire Company B because it will give us higher current values during the first 5 years and higher returns of the investment.

Essay on Mandatory Uniforms in Public Schools - 2537 Words
Mandatory Uniforms in Public Schools Do you want equality among students in your childs school? Do you want less violence within your childs school? Would you like your daughter to concentrate more on her schoolwork and less on what name brand jeans she is wearing? All this is possible with mandatory uniform policies in public school districts. School uniforms may seem outdated for some people, but in many cases they can improve school spirit, attendance and student behavior. According to The Humanist magazine, former President Bill Clintons 1996 State of the Union Address called for all 16,000 school districts in the country to adopt a uniform policy. The President stated, If it means that teenagers will stop killing eachâ⬠¦show more contentâ⬠¦The American Civil Liberties Union (ACLU) also argues that mandatory uniforms violate students free expression right (King, screen 3). When wearing uniforms children feel like they have limits on their personal expression. To illustrate, Students perceive their cl othing as a way to explicit their emotions, show their creative abilities, express their opinions, and display individualism; if they have to wear uniforms to school the students opportunity to reveal their personality is eliminated. Newsweek reports that some teachers and principals sympathize with the students. A principal at a middle school in Sherman Oaks, California, Norman Isaacs believes that with a students clothing a teacher can get insights on what is going on in the students personal life. He states, our counselors and teachers monitor the way kids are dressed if we see a big change in the way a student dresses, that sends a signal and tells us we need to address that person (qtd in Uniforms Rule, screen 2). Students feel that uniforms at school create a military environment.
