History of Black and Indian relations among the Florida Seminoles Essay

History of Black and Indian relations among the Florida Seminoles - Essay Example As early as 1689, Africans fled from British-American colonies to the Spanish controlled Florida in search of freedom. A new influx of these freedom-seeking blacks reached Florida during the American Revolution. During this Revolution, the American slaves agreed to fight for the British in exchange for liberty. They built settlements near the Seminoles as both had a common interest to escape slavery. They built separate villages of thatched-roof houses surrounded by fields of corn and swamp rice, and they maintained friendly relations with the mixed population of refugee Indians (Joseph A Opala). The Seminoles Indians also allied with the British for this fight. This brought the two – the Africans and the Indian Seminoles - into increased contact with each other. Members of both the communities sided with the British during the War of 1812. This helped them to solidify their ties. Gradually the two groups came to view themselves as part of the same organized tribe. Their relat ions solidified to such an extent that the US Government could not break them apart. Intermarriages and friendships were common. They became such close allies that they came to be known as the Black Seminoles. At this point when the Africans and the Indian Seminoles first came into contact, the Seminoles were themselves recent immigrants to Florida. The Africans adopted their clothing and the Indians acquired taste for rice and appreciation for their music and folklore. At that time, they were known as Gullahs.

Developing business - Essay Example be specific considering the underlying report discusses the growing dimensions with respect to different in sustainability in social and environmental factors as well as financial sustainability that is interpreted as going concern for business. In addition, the ways to reconcile the difference between two concepts, obstacles and future implications with respect to the operation and reporting are discussed. In due course, different conceptual aspect is noted and discussed with examples. Finally, the recommendation based conclusion is proposed to adapt the real sustainability imperative that brings financial, social and environmental aspects all on a single page. The raising concerns related to the adverse impacts that businesses are creating on society traces its history in the 1700. The concerns arose as a result of growing child labor and working conditions in factories and mines in UK. However, it was late in 1970s when the voice gained momentum and finally with the turn of the century, the concept is now set as among the priority concerns of the business (Honeyman, 2007 and Ceres, n.d.). The overall evolution of sustainability has grown from rejection for the concept of the transformation of business as shown waves of sustainability as follows: According to the definition put forward by United Nation’s Global Compact, a sustainability is an imperative for the for success in the long-term with the assurance that the business also delivers value all across the society (UN Global Pact, n.d.). However, the concept of value varies. For example, Golub, et al. (2000) discussed the value delivery to customers while Hartlen (2014) clearly states that the definition of value varies from the interest of one stakeholder to another. Hence, for providing the direction for value to the business, UN Global impact has identified five dimension of delivering value to the society. The five dimensions are depicted in the image below: All these collectively result in the

Functional Behavioural Assessment Case Study

Functional Behavioural Assessment Case Study Functional Behavioral Assessments for Sean Siobhan L. Healy Introduction Mrs. Valdez, a second grade teacher at Hacienda Elementary School, contacted me via email requesting my services regarding one of her students. Mrs. Valdez would like me to meet with her and several administrators, including the principal of Hacienda Elementary School, to discuss the student’s behavioral issues. The subject of concern is Sean, a 9 year old boy, who had been held back to repeat second grade due to his ADHD and the resulting inattentiveness and failing grades. Sean is described as a bright and lovable boy at school and at home but due to his (recently diagnosed) ADHD, he is often â€Å"inattentive† during class, jumps out of his seat and throws crumbled up school papers at peers when asked to complete a task. His lack of concentration and the inability to finish any task at school have earned him failing grades during the prior school year and parents and teachers fear that he may be failing second grade again, if nothing is done to help him. Sean’s parents are against any pharmaceutical medications to treat his ADHD and they have consulted with an herbal doctor to treat the condition. Now, Mrs. Valdez has asked me to develop a behavior intervention plan for Sean, in order for him to succeed academically and socially during the current school year. The operational target behaviors seen in Sean are, a) inattention, in form of not paying attention to teachers’ instructions and school work, b) out-of-seat behavior, defined as any time Sean’s behind was not making contact with his chair, and c) throwing items (i.e., crumbled up papers) at peers. If my interdisciplinary team and I are able to describe the specific purposes of a Functional Behavioral Assessment for Sean, to the Hacienda Elementary School administrators during the planning meeting, then we will be able to design and implement an effective treatment plan for this student based on the results of the proposed FBA. Functional Behavioral Assessments are used to determine why an individual exhibits certain behaviors and in what way the environment influences the individual and their behaviors. In the beginning, the method of analyzing behavior was created with the autistic and severely intellectually disabled population in mind, but it can be applied to any individual with problem behaviors. According to the State Board of Education, North Carolina (2015), â€Å"The reauthorized Individuals with Disabilities Education Act requires that a Functional Behavioral Assessment be conducted if a behavior was a manifestation of the disability or, as appropriate, for other disciplinary removals† (http://ec.ncpublicschools.gov). In many schools, the Individual Education Program Team (IEP team) develops an assessment plan to address problem behaviors. During IEP team meetings, target behaviors must be identified and specified. Decisions must be made about who will conduct each component of an FBA, and a timeline as to when the assessment will be completed is set. Usually, the IEP team will meet to discuss the assessment results and to design and implement behavioral interventions. Sometimes, The IEP team and members of a school administration need to bring in an independent team of experts in order to exhaust all possibilities of an effective FBA, especially in the case of Sean (State Board of Education, NC, 2015). Indirect Assessments are performed when information about antecedents, consequences, and critical variables, needs to be gathered indirectly via interviews, screening forms, and rating scales. The Indirect Assessments are considered an adjunct to direct measures, as the data gathered from these measures is usually not considered quite as reliable. However, Indirect Assessments are often the first procedures performed in an FBA because the observer is able to record meaningful observations and he or she may begin the construction of hypotheses about the function of behaviors rather quickly (Steege Watson, 2013). The interdisciplinary team would first assess Sean by conducting five general steps of a Functional Analysis. Step one would be a Functional Assessment Interview during which the team would question at least two or three persons who know Sean very well and who have been involved in the situations in which the behaviors occurred (most likely his parents and Mrs. Valdez). The interview would focus on identifying observable behaviors displayed by our referred student. For example, when addressing Sean’s â€Å"inattentive† behavior, the team should ask Mrs. Valdez, the teacher, to clearly and concisely describe the observable characteristics that constitute â€Å"inattentive† behavior. It is important to note during the interview, what function Sean’s behaviors serve. For example, his out-of-seat behavior may actually serve two different functions, one to get attention from his peers by jumping out of his seat, and two to escape from or avoid academic instruct ion from the teacher. This type of information will be relevant for the entire process of FBA, because, if the functions are different, the resulting interventions may be different as well (Steege Watson, 2013). With a typical ABC Assessment, when the interfering behaviors occur, the observer is expected to record those behaviors and the immediate antecedent and consequence variables. Observers often identify one immediate antecedent and one immediate consequence that occur during a behavioral event. For example, the ABC Interviewer could record the following in Sean’s classroom: A: Antecedent: Teacher, Mrs. Valdez, requests Sean to sit down and complete his task, B: Behavior: Sean jumps up, crumbles his school paper, and throws it at a peer, C: Consequence: Mrs. Valdez verbally reprimands Sean and sends him to the principals office. However, in this instance, a single ABC recording was not able to identify all of the relevant variables connected to this behavioral incident because, there were a number of additional incidents preceding this recording. Oftentimes, with the occurrence of a series of behavioral incidents, the observers verbally report or record only the final incident (S teege Watson, 2013). Thus, a Behavioral Stream Interview (BSI) could be performed in Sean’s case, in which contextual variables that are associated with the interfering behaviors, can be identified. This kind of interview centers on the idea that there are many variables, including individual, antecedent, and consequence variables in Sean’s environment that impact his challenging behaviors. These different variables often interact in a predictable manner and are not stagnant. Steege and Watson (2013), compare â€Å"the ongoing flow of behavior and related stimuli† to a river, â€Å"sometimes a stream that gently meanders through a meadow, and at other times a raging torrent rushing through mountainous canyons† (p.106). The BSI has the potential of identifying patterns by calculating the sequence in which the variables occur. It can be compared to a movie strip of several captured pictures in a sequence, unlike a single photograph â€Å"of a singular antecedent–behavior–consequence interaction (A-B-C)† (Steege Watson, 2013, p. 106). Furthermore, data could be collected through a questionnaire such as the Child Behavior Checklist (CBCL; Achenbach, 1991, as cited in Sattler, 2002) which measures internalizing and externalizing problems in children and adolescents. The CBCL is designed for parents of children and adolescents ages 4 to 18 years old. The rationale for conducting the interview is to observe the target behavior. The reason for utilizing the CBCL is that it includes a Teachers Report form (TRF, Achenbach, 1991, as cited in Sattler, 2002). According to Sattler, the TRF has satisfactory validity. Functioning Assessment Screening Tools or a Motivation Assessment Scale may additionally be used. The Functional Behavioral Assessment Screening Form (FBASF) would be a particularly useful tool to record data about, a) interfering behaviors (i.e., target problem behaviors), b) behavioral strengths (i.e., characteristics that are functional and appropriate, adaptive behaviors, and skills), c) Reinforcers (i.e., stimuli that are preferred by the student, people, activities, and events), d) Communication skills (i.e., verbal expressions, gestures, signs, or devices). In the context of Sean’s case, his behaviors too, are not occurring randomly, but are caused by an interaction between antecedent, individual, and consequence variables (Steege Watson, 2013). Direct descriptive Functional Behavioral Assessments, on the other hand, are very powerful tools in school settings. They are powerful because the procedures center on direct observations of behaviors in situations and settings in which the target behaviors occur. Systematic observations, and not just mere indirect information lead to solid hypotheses on function and triggers of behaviors (Steege Watson). Therefore, step two in a Functional Analysis would be a Direct Observation and collection of data by observing Sean’s target behaviors directly. The team could do a Sequence Analysis by recording antecedents, behavior, and consequence (a Maladaptive Behavior Card can be used for this purpose). Furthermore, the frequency and rate of the behavior would be recorded. The frequency of occurrence per unit of time, for example, would be 30 behaviors divided by 20 min of observation = 1.5 behaviors per minute or about 3 behaviors every two minutes. Next, the duration of each behavior and the latency (which is the duration of time between a stimulus and a response) would be recorded, for example, how soon after the stimulus does Sean begin to jump up or throw paper balls at classmates (Carbone Zecchin, 2014). Step three deals with experimental manipulations if they are feasible based on the severity of the behaviors. This procedure enables the observer to empirically test the functions of the behavior. The situations in which the behaviors occur most frequently suggest the function of the behavior. In order to test for the functions of the maladaptive behavior, the interdisciplinary team would have to perform an Alone Condition Test in which Sean would be alone without any stimulation and then count if any aggressive behavior occurred within a 20 minute session. Next, an Attention Condition-Test is performed to find out if the behavior is maintained by attention. This involves engaging Sean in a preferred activity and if a maladaptive behavior occurs, the team would give him 10 seconds of attention after each occurrence of the target behaviors by saying â€Å"Sean, don’t throw anything at your classmate, you could hurt her!† The team would count the number of times the behav iors occurred and this session would last 20 minutes. Then, comes the Demand Condition – Test, which is designed to explore if a behavior is maintained by Escape or Avoidance. The interdisciplinary team will place Sean in a demanding task or situation and allow him to escape (or leave the situation) each time the target behavior occurs. The team would wait for about a minute and then direct Sean back to the demand situation or task, while keeping count of the number of times the behavior occurs. This session should also last 20 minutes (Carbone Zecchin, 2014). Last but not least, the Play Condition-Test will be performed, which is a control condition. In this scenario, the interdisciplinary team would place Sean in an enriched reinforcing environment, allow him to engage in preferred activities of his choosing, and count the number of times the behavior occurs. This session, again, will last 20 minutes. Step four will be a Functional Analysis Summary, to include a form/chart outlining the Functional Analysis Interviews conducted, the Direct Observation Data collected, and the Experimental Manipulation implemented. Step five will outline a Behavior Lesson Plan and after carefully choosing of an intervention, this will be called an Intervention Lesson Plan for Sean (Carbone Zecchin, 2014). In the literature by Steege Watson (2013),  The Conditional Probability Record (CPR) is a form that  allows the observer to simultaneously observe and record the  antecedents and consequences of behavior. The advantage of  doing so allows for the analysis of the likelihood  (probability) of a behavior given a particular antecedent and  the likelihood of a particular consequence following a  behavior (p. 134). Let’s say, we take a 5-minute excerpt from a 15-minute observation period, and it shows that Sean was out of his seat during 70% of the intervals, then, of the intervals in which Sean was out of his seat, 51% of those resulted in a verbal reprimand by Mrs. Valdez and 43% resulted in her physically guiding Sean back into his seat. Therefore, Seans out-of-seat behavior resulted in some form of attention by Mrs. Valdez in 94% of the intervals. On the other hand, when Sean was working on his assigned tasks, it resulted in no attention, verbal or physical, from Mrs. Valdez. So, only in 29% of the intervals in which Sean was working on his tasks, was Mrs. Valdez near him. Therefore, one of the hypotheses is that Seans out-of-seat behavior is maintained by Mrs. Valdez’ attention because doing so is more than three times as likely to result in some form her attention than working. During these observations, there may be some influence by Sean’s peers in the form of looki ng at him (23% of the intervals) or cheering him on (18%), however these consequences were not as probable as Mrs. Valdez’ attention. Additionally, there also appears to be a negative reinforcement because Sean is able to escape from the assigned task by getting out of his seat. Antecedent and consequent possibilities are verified by further observation and analysis (Steege Watson, 2013). The interdisciplinary team could complete a Functional Behavioral Assessment Observation Form (FBAOF) for Sean. This is an assessment procedure involving direct observation and recording data of interfering behaviors and contextual variables. The FBAOF is generally used to record â€Å"behavioral episodes† or â€Å"behavioral incidents† that involve one single interfering behavior. The observer uses an FBAOF each time the interfering behavior occurs to record, 1) Date and time of day, 2) Setting events (i.e., activities, tasks, places, etc.), 3) Antecedents (i.e., events that appear to trigger the behavior), 4) Behavior (i.e., the defined interfering/target behavior), 5) Consequence (i.e., events following the interfering behavior), 6) Effect (i.e., change in rate or intensity of occurrence of the behavior), 7) Staff (i.e., person recording the data, working directly with Sean). Should the interdisciplinary team use the FBAOF, they must differentiate between an †a ntecedent† and a â€Å"setting event.† The antecedent is a precipitating variable (i.e., a specific event triggering a behavior), while the setting event is just the general situation that the behavior occurred in (Steege Watson, 2013). Last, but not least, the interdisciplinary team could utilize the Task Analysis Recording Procedure (TARP), which is an effective â€Å"procedure for teaching functional life skills and for progress monitoring† (Steege Watson, 2013, p. 146). It is used for documenting a person’s level of performance on specific tasks, instructional procedures, identification of effective and ineffective instructional prompts, and to document levels of occurrence of interfering behaviors, especially in the context of instructional programs (Steege Watson, 2013). TARP is a useful tool for recording a decrease of interfering behaviors, while, at the same time, documenting an increase in desirable and appropriate behaviors. For example, we could use the TARP data recording in order to measure Sean’s occurrences of negative behaviors within a social or classroom setting, while, at the same time, recording any desirable behavior, such as doing his assigned tasks independently. This procedure is mostly used in individuals with autism who reside in group homes but TARP could be used in Sean’s case because of his ADHD diagnosis and being in a â€Å"group setting† (classroom) (Steege Watson, 2013). It is important for the interdisciplinary team to put emphasis on the vast selection of indirect and direct descriptive FBA procedures. In many cases, a combination of both types in an assessment process is adequate for an assessment and an understanding of behavioral functions. A comprehensive mixture of several procedures can lead to the design of effective intervention plans (Steege Watson, 3013). References Carbone, V. J., Ph.D., BCBA Zecchin, G., BCABA. (2014).

How Does A Firm?s Pricing Poli :: essays research papers

How does a firm’s pricing policy relate to the product’s life cycle? When a company launches a new product, it knows the product won’t last forever. However, the company does expect to earn a satisfactory profit to cover all the effort and risk that went into launching it. A firm can never accurately predict the lifetime of a product, but the lifetime involves four distinct stages. These four stages are collectively known as the Product Life Cycle (PLC). The first stage is the introduction stage, when the product is first launched. Sales growth tend to be low as consumers are ‘introduced’ to the existence of the product. At this stage therefore, profits are negative or low because of the low sales and high distribution and promotion expenses. Much money is needed to attract distributors and build their inventories. Promotion spending is especially high to inform customers of the new product and get them to try it. One of the biggest launches in recent history is that of the DVD player. Not only is this a new product, it’s a whole new market. Industry executives have named DVD-Video the "Medium of the Millennium" and boast that DVD-Video is the fastest growing new packaged media format launch in history with close to 5.4 million DVD-Video players shipped to retail since the format launched nationally in the U.S. in autumn 1997 (Consumer Electronics Association). The outlook for next year is equally promising. The DVD Entertainment Group estimates that hardware shipments will double to eight million DVD-Video players in 2000. And, based on the success of the format exceeding all previous forecasts that number could be even higher. The group also estimates that the installed base will more than exceed 10 percent of US households, a benchmark of success for a consumer electronics product. The surge in hardware sales is a positive boost for retailers. In 1999, DVD-Video hardware represented more than $1 billion in retail sales. This includes stand-alone players only and does not include DVD-ROM drives or other home theater products. There are now nearly 70 DVD Video player models marketed under 30 different consumer electronics brands. In only its third year in the marketplace, DVD-Video player prices have declined significantly. According to Intelect ASW, the average price sold for a DVD-Video player was $298 in November, down 30 percent from $428 at the same time last year. Some players and models are available for less than $200 making the format accessible to the mass market.

Married vs Single Essay

Most people would agree that getting married is a happy occasion. People think their lives are going to be better when they get married because the husband and wife are going to spend their times together. However, some people think when they are single, their lives are going to be better because of they have more freedom than when they get married. Some of the differences are social relationships and free time. The first difference is social relationships. For example, people who are married are together until they get divorced or until death. Married couples have social relationships with their children when they talk and express their inner feelings. Also, that is how parents have close relationships with their children. On the other hand, single people are living different lifestyles when I come to social relationships. In fact, single people are having social relationships when they are talking with a friend or boyfriend/girlfriend. Single people can make their own decision about who or who not to have a social relationship with. The second difference is free time. To better explain, people who get married are responsible to spend quality time with their family. They also have to spend time assisting their children with their homework. Truthfully speaking, responsible husbands or wives need to spend time together in order to avoid future problems. In contrast, single people spend their free time anyway they want to. If truth needs to be told, they don’t have to make any commitments toward anybody. Finally, married people have a busy time with their family such as working, shopping, and they can’t spend too much time with friends. In contrast, single people have their school, work, and shopping, and they have a lot of freedom to hang out with their friends In brief, married and single people are very different in many ways. As I have shown it in the above paragraphs, they are not similar in their relationship as well as their free time. In my opinion, people who believe that married people and single people are alike are fooling themselves. It is important to remember that married and single people don’t have much in common.

Marquis de Vauvenargues, a French moralist and essayist said that  the greatest achievement of the human spirit is to live up to one's opportunities and make the most of one's resources.   My work experience as a research analyst, a school manager and a full time classroom teacher widened the horizon of my career and led me to pursue a study that will enable me to establish a business that would create jobs to people in my community.My initial job as a research analyst and laboratory manager at Biosphere 2 Center in Arizona provided me with the opportunity to design the CO2 control system and implemented new chemical procedures.   I was also given the task of supervising the research works and thesis of students in the undergraduate level.Due to my desire to explore more avenues in the field of science, I moved to Columbia University in New York and worked as a laboratory manager and researcher.   In Columbia University, the task of managing and maintaining the laboratory of Lamont Doherty Earth Observatory, a world class state of the art research institution specializing in the Earth sciences, sharpened my managerial skills.As my task also included conducting data collection, analyses, interpretation and data reduction, my knowledge and skills in research and statistics was enhanced.   I developed good analytical and problem solving skills as well as communication and interpersonal skills through constant interaction with tenured faculty, accomplished scientist and highly motivated graduate students   Ã‚  I also designed and implemented new chemical procedures.Although I grew up in India, I was fortunate to be given a rare opportunity to work in a prestigious university and laboratory center in the United States.   Although the transition was challenging, the experience was rewarding.   The administrative and research opportunities that were given to me in my first two jobs enriched my knowledge and skills but I felt a nagging call to share my knowledge.Hence, I worked as an adjunct professor at Bergen Community College in New Jersey and eventually in Herman Ridder Intermediate School and Bronx Academy in New York.   My students became the recipients of the knowledge that I have gained from my previous exposure in a fully equipped and modernized laboratory.   As a full-time environmental science and mathematics teacher for grades 7-12 level, I was able to awaken the minds of students to appreciate mathematics.As I taught them a number of ways to approach and solve mathematical problems, I also found out the source of their weaknesses and their lack of enthusiasm in the subject area.   Some could not solve complex problems due to lack of knowledge in the basic principles of mathematics.   Others never had a teacher who used games as a way to make students enjoy the subject.Science and mathematics are closely related and I believe that the progress of the nation is partly dependent on the scientific discoveries and technological advancement that the future generation can offer.   Working with poorly motivated students with behavioral problems and those who were hostile and hopeless about their situation was very challenging.   The personal conviction to increase students’ achievement led me to organize an innovative volunteer program whereby students requiring assistance outside the classroom were tutored during lunch break.I also identified student’s individualism and developed curriculum to accommodate their diverse learning styles and maximize their potentials.   To facilitate learning, a curriculum was developed to ease instruction of individual, small groups and classes of 40 students.   Open communication and close monitoring of student’s progress facilitated learning and improved academic achievements.  Parental involvements in the academic and extra-curricular activities of students were strongly encouraged. Comprehensive mathematics and science learning resource were also created so students were able to take home and learn materials with their parents.I had my last employment in Herman Ridder Intermediate School in New York where I was designated by the school principal to serve as a teacher and business manager due to my analytical and interpersonal skills.   I directly collaborated with the principal in acquiring educational materials and developing after school learning programs.I have also worked on budgetary matters relating to the implementation of assigned programs and performed administrative functions in implementing budgetary programs, policies and procedures.   School and district budget were planned, reconciled and effectively managed.   My exposure in managing school finances led me to discover that I had talent for budgeting and managing small teams.   This has also confirmed my strong desire to focus my future career in business management.Having a solid educational background in geology, earth and environme ntal science, and vast exposure and experience in the field of management, education, research and statistics in the United States and India, I would like to further my studies in Business Administration by being part of the graduate program in Rice University.Backed by my knowledge and experience in data analyses, data interpretation, research background and strong quantitative skills, I want to have a stronger grasp of business management as I intend to be a Petroleum industry marketing and market research consultant after my graduate studies.I was impressed with the sense of cooperation and team spirit between the faculty members and students of Rice University when I visited the campus twice and spoke with   Dr. Seetharaman and several students.   I believe that with the small class size, personal interaction with fellow students and faculty, hands on training and excellent program of Rice University, I will gain more exposure and experience in dealing with problems and issu es related to the management of business in relation to Petroleum industry.In the near future, I would like to serve my community by establishing a business so I can provide more jobs and contribute to the economy of the country.   This is the best time to pursue a Masters in Business Administration degree after gaining a vast experience in managing people with different background, attitudes, personality and academic achievement.After being a stay at home dad for two years, I could not wait to go back to school this fall to further my studies and eventually work and in a competitive and challenging field.

Becoming a Parent essays

Becoming a Parent essays A child is an incredible responsibility, and a bit of planning goes a long way. This is not an exhaustive list of the financial preparations new parents should be aware of before welcoming a baby, but it is a start. After a child is born there are many other financial concerns such as paying for college and adding them as beneficiaries to your will and retirement accounts. Anyway, I think parenting never really ends, but being financially prepared from the start will give you more time with your child.(Xing Lu's Bio on, 12 August 2008) There are several reasons ways our life will be changed with a new baby when she/he comes to our life. The first reason is financial problems. You need a lot of dipper for kids. As a matter of fact, you might spend about $350 for a kid per week. Also, you need to purchase clothes for kids. Another point is this; you often need to take him/her to the doctors. When the kids are sick or have a fewer, you have to shot to them, and take some medicine. Another thing is child care. If the parent goes to work both of them continuously, it has some problems for kid. For example, heshe doesnt have anyone to take care of him/her for the rest of the day. So, it should be one of the parents stay at home and take care of him/her. Therefore, the family income will be reduced. Secondly, free time for the parent is another reason. For instance, they cannot go to some recreational places to have fun together; or maybe if they have a plan to go to cruise and take fun times, they cannot have a plan to go to the trip, because they have to take care of their baby. Maybe they can bring the baby with them, but the baby bothers them in the trip. For example, when one of relative went to the cruise last summer with their baby, they told I suffered a lot when their baby was with them like crying the baby most of the time, when they went to the bar and they had gone to eat. Another point for free time is if you get a b...

Cooperative Learning Models

Cooperative Learning Models Introduction Despite the numerous learning strategies adopted in schools, cooperative learning has been identified as the most efficient. This strategy of instruction and learning has been adequately adopted in many academic institution as well as corporate institutions for educating people.Advertising We will write a custom essay sample on Cooperative Learning Models specifically for you for only $16.05 $11/page Learn More The advantages of this learning process are extensive. It has been observed that cooperative learning gives students the opportunity to acquire academic, social and cognitive skills in an efficient and effective manner. Cooperative learning has been identified to be highly advantageous in the sense that it helps students to solve problems together as well as solution to conflicting ideas. Individual weaknesses and difference in learning process can be adequately countered through the adoption of cooperative learning thus making it an effi cient learning strategy. There are various cooperative learning models which can be efficiently adopted by the teacher for instruction. Some of the main cooperative learning models include; the Graffiti model, the jigsaw model, the academic controversy model and the student teams-achievement division (STAD) model. Despite the numerous efficiencies of each of the cooperative learning models, each is endowed with varied characteristics. This essay will compare and contrast the above highlighted cooperative learning models. The four cooperative learning models including the; Graffiti model, the academic controversy model, the jigsaw model, and the student teams-achievement division (STAD) model have a high sense of commonness. An analysis of the four models of cooperative learning indicates that each of the models is aimed at ensuring integration of students’ ideas in the classroom. The concept of working together as a group in the classroom is explicitly demonstrated by each of the model. This aspect depicts the similarities of the models in enhancing supportive cooperative learning. In the case of graffiti model, students are offered a chance to work in groups on previously identified topics and questions. This helps students to share individual and group knowledge on the topic. This scenario is also depicted in the jigsaw model whereby students are divided into groups and each member assigned with some piece of information. This individual information is integrated together with those of other members thus making it possible to realise the class objectives collectively. In the case of academic controversy model, students are offered adequate freedom to express their understanding on a certain topic.Advertising Looking for essay on education? Let's see if we can help you! Get your first paper with 15% OFF Learn More This creates an open forum for debate, discussion and conflict of ideas thus leading to sharing of information. On t he other hand, the student teams-achievement division (STaD) model also replicates the other models in the sense that it is based on team learning. Students are in this case divided in teams of about five and assigned with specific topics for discussion after which they present to the whole class. On the contrary, the various cooperative learning models have demonstrated significant differences. This is based on the nature of the teams adopted in instruction as well as distribution of materials or information to be discussed. In the graffiti model, students are required to discuss in groups previously identified topics. Each group is supposed to make summaries on all class’s responses. A special aspect of this model is that it ensures face-to-face interactions and positive interdependence among the students. This is in contrast to jigsaw model whereby students are offered with different materials to discuss and share with their colleagues. Academic controversy model on the ot her hand entails open discussion among students, whereby they share their knowledge and experiences on a certain question or topic. In the case of student teams-academic division (STaD) model, students study in groups. These are heterogeneous and representative groups of the entire class. After the group discussions, the information or results of each groups is discussed to the whole class. Conclusion In summation, it has been clearly evident that cooperative learning is one of the most effective learning strategies. This form of learning ensures smooth integration of student’s knowledge in the classroom. Student gain a lot of experience and knowledge on social, cognitive and academic skills. The concept of group work is embraced in cooperative learning whereby students are able to solve problems together.

A Series Of Unfortunate Events, Analysis

A Series Of Unfortunate Events, Analysis This movie tells about The Baudelaires orphans: Violet; Klaus; and Sunny. Violet is fourteen years old, Klaus is twelve years old, and Sunny is still an infant. Each of these orphans has awesome ability: Violet can find and create everything from the things around her as good as a scientist; Klaus loves reading so much and amazingly he remembers all what he read even in details; and then Sunny, the youngest, her teeth are so strong and she bites almost everything. Their parents are killed in a fire that also destroyed their house. Mr. Poe, the family banker, then sends the children to live with Count Olaf, an actor who is their closest relative. Count Olaf treats the children awfully. Soon The Baudelaires know that Count Olaf just wants to take their parents’ richness. One time because of a coincidence, Mr. Poe thinks that Count Olaf is not a responsible parent so that Mr. Poe takes back the children from Count Olaf. Olaf, pretending to have an emotional goodbye with The Baud elaires, promises that he will find them again and get their fortune. Mr. Poe sends the children to live with their uncle, Dr. Montgomery Montgomery, a cheerfully herpetologist. The Baudelaires live happily with Uncle Monty. Nonetheless, Count Olaf comes in disguise to Uncle Monty’s house as his new assistant for herpetology and he killed Uncle Monty. The orphans are then sent to live with Aunt Josephine who lives in a house on the edge of a cliff above the Lake Lachrymose. However, Count Olaf catches the children wherever they go in order to get an opportunity to grab the Baudelaires’ wealth. He does camouflages to fool other guardians of the Baudelaires. Count Olaf causes the death of Aunt Josephine and makes himself as if he is the children’s savior. As a result, Mr. Poe gives custody back to Count Olaf, seeing how he rescued the children. Mr. Poe reveals to Count Olaf that he would not inherit the children’s fortune even if they died, with the excepti on of blood relatives, or married couples. Count Olaf invites Mr. Poe and people he knows to his play which stars himself and Violet as the leads. It is a trap for the Baudelaires so that Count Olaf can gain access to Violet’s inheritance. Klaus notices Count Olaf’s bad plan. Somehow he ruins the play and makes people realize the tyranny of Count Olaf and then arrest him. Moreover, Klaus notices that the death of his parents is not merely an accident, but it was Count Olaf’s deed. Eventually, the Baudelaires are safe and kept away from Count Olaf. The reason the writer choose this movie to be analyzed is because the writer is indeed interested in this movie from the first time the writer saw it. This movie is one of 21th century literary works which depicts chains of a unique story which is not clichà ©. From its title, it is discernible that this movie imparts a kind of tragedy which involves life/moral values. Moreover, it involves the hamartia, anagnorisis, peripeteia, and catharsis. This is why the writer decides to use Aristotelian theory to analyze this movie, because hamartia, anagnorisis, peripeteia, and catharsis are the key elements of the theory.

However, another form of parenting, known as gender neutral parenting (GNP), shifts focus away from categorizing children into specific genders basing only on their biological sex, allowing them to find their own spots of comfort on the gender continuum. In that sense, parents should raise their children in gender-neutral homes where kids can construct their own identities because parents have the most influence over their children’s lives and have a responsibility to educate children. Because children mimic their parents’ behavior, parents are best placed to influence them towards gender neutrality. Children begin mimicry at birth, but by the time they are one year old, it turns into true imitation, which means they imitate with intent (Zentall, 2006). They will observe and process information conveyed through their parents’ behavior, and since they already understand that such behavior has significance, they will copy it. In that way, gender neutrality can be imparted on them. Gender neutrality in parenting pertains to not referring to any one particular sex, which means that boys and girls are brought up the same. The most basic indicators of GNP include allowing boys to play with toys and girls to play with toys usually associated with boys, and not emphasizing on gender by way and type of dressing. Parents, therefore, should make the homes in which they raise their children gender-neutral. It is significant for parents to acknowledge that GNP is not aimed at abolishing female or male concepts and creating a genderless world. Rather, its underlying objective is not to force any predetermined gender standards onto children. It simply provides that a child’s identity should not be suppressed by the parents, which is usually the case when children are restricted to traditional gender

Ethics and the ASCE Report Card for Americas Infrastructure Assignment

Ethics and the ASCE Report Card for Americas Infrastructure - Assignment Example This is compounded with infringement into the local cultures while executing construction projects (McAnally 75). Another critical ethical concern is failure of imported technology to conform to socio-economic policies of the local industries. This pertains particularly to international regulations on patents which suppress the progressive socio-economic strategy of developing economies. Competitive strategies of civil engineering firms to adopt common language and use the same in foreign assignments have a significant ethical drawback. This has to do with foreign engineering using their language which may not be effective to the locals and the consequence is skewed decision making. For instance, Civil engineers from firms that use English as common language are likely to dominate project evaluation and monitoring process and make the locals to shy aware hence limiting participatory decision making as far as the interests of the local community is concerned. This has led to environme ntal degradation, disregard of cultural norms which amounts to unethical consequences of globalization in civil engineering. ASCE maintains transparency and accountability of the engineers in various locations of their assignments. Since one of the ethical codes is to serve humanity, involvement of the local community in foreign assignment is facilitated through use of interpreters and participatory decision making which must incorporate input of local community. Another approach towards remedying this problem by ASCE code of ethics emphasizes involvement of the local engineers to link the foreigners with the host community (McAnally 77). However, it is worth to note that ASCE code of ethics has standardized rules on projects execution procedures which at times clash with the local legal framework. United States is considered the powerhouse of ultra-modern technology and offers the best civil engineering

Juvenile justice system- harsh punishments vs. lighter punishments Essay

Juvenile justice system- harsh punishments vs. lighter punishments - Essay Example There is also the lack of understanding among citizens on the social, political and economic perspectives that cause juvenile crime and the juvenile justice practice. Even though most people do not comprehend the vitality of the juvenile justice system, there have been strong discussions on the causes of crime by the youth and the possible ways of handling them (Champion, Merlo and Benekos 34). There are varied position held by the public concerning this issue, some hold the view that there measures should be put in place that will ensure such crimes are prevented and rehabilitate the young offender. Other members of the public call for the establishment of harsher punishment to the young criminals. They demand that youths who commit crimes be held accountable as adults (Elrod and Ryder 5). There has been a growing dilemma of youth gang violence in Central America. Youth violence is a great worry since it affects the country’s safety and the health of the public. However, some of the strategies put in place so as to address the problem are not successful. It has been noted that the approaches lead to the infringement of human rights hence leading to serious lawful challenges. Violent gangs have been reported to be taking part in injurious actions such as drug abuse. In addition, violent gangs take part in theft and robbery of properties of their neighbors. Juvenile justice systems have been established to ensure that cries committed by the youths are prevented from taking root in the society. Introduction Jane is a woman juvenile detention officer and Jack is a resident of New York, they hold the view that children who commit crime should be rehabilitated rather than punished and measures should be put in place to ensure that crimes involving the juveniles are prevented from occurring in the society. On the contrary, Kennedy is a law enforcement officer while Brian is resident of Los Angeles. They hold the view that the youth who engage in criminal activ ities should be given equal punishment the same as the punishment given to adults. Scenario The issue of juvenile justice system and the approach in which it should take, whether rehabilitative or punishment approach, and the best approach which should be adopted have dominated the public debate for several years now. It is evident that young people engage in serious criminal activities. However, most crimes committed by the young ones do not lead to serious injury or loss of property. The public has had to debate on the best way to approach the issue in order to correct the illegal behavior of the youths (Krisberg 3). There have also been concerns on the best approaches that can effectively help the youth in learning from their mistakes so as to enable them make right decisions concerning their lives now and in the future (Klein 55). Young children who commit crime constitute a diverse population. These young criminals vary depending on their psychological and biological factors as well as the social environment in which they live. However, their biological, social and psychological variation need to taken into account when considering which type of approach whether rehabilitative or be punished. Several states in the United States have placed the age limit to the juvenile justice system jurisdiction a t age 17. When the youths attain the age of 18 years, they are subject to the jurisdiction in the adult justice system. Further, some states have a lower age limit for admission to juvenile court. The age limit often varies from the age of 6 years to 10 years. In cases whereby a lower age limit exists, younger children with the age below the statutory specified age cannot be considered in the

Freud and Psychoanalysis Research Paper Example | Topics and Well Written Essays - 2000 words

Freud and Psychoanalysis - Research Paper Example ace-time matrix of the Freudian dream clearly reflects that mind is the part of human being in which body is the spatial restriction and limitation of human mind. Obviously mind can go beyond this limitation through his capability of imagination. In the book, â€Å"Studies on Hysteria† Freud and Breuer (1893) recognize the physicality and bodily experience as a contribution to the development of personality. But this approach of Freud and Breuer (1893) to body and mind, though it resembles to that of Damasio’s (1992), differs from the neurobiological approach on the ground that though both mind and personality are shaped by bodily feeling, Freud and Breuer’s (1895; 1895) concept of mind does not acknowledge the role of the organic function of human brain to the development of mind. According to them the physical feelings like trauma are stored in human mind first in the form of memory of a foreign entity and then in the form of an agent that determines his future functions of body and mind. Freud’s theory of personality primarily evolves from his approach to the concept of mind. As a theorist, Freud (1916) crucially depends on the structural existence of human mind that is more or less detached from physiological existence of human being. Irrespective of the relationship of mind with human body, the physical existence, Freud’s â€Å"mind† closely follows a structural pattern that effectively explains the different questions -regarding the relationship of mind with various behavioral pattern of a person- of the psychoanalysts of his age. In comparison with the German Philosopher Mauss’s collective notion of â€Å"person† which changes from time to time and society to society, Freud’s concept of ‘person’ appears to be an intact one that is supposed to function universally (Ziegler, 2002, p. 81). But Freud’s theory of personality that exclusively revolves around a person’s body apparently fails to explai n the relationship between body and mind that

If King Duncan wasn’t murdered, Macbeth would still be the innocent kind man that he once was and his wife would still be alive.

Concrete Elastic Modulus For Various Aggregate Types Construction Essay

Concrete Elastic Modulus For Various Aggregate Types Construction Essay Concrete generally, is an inevitable constructional material in civil Engineering for profitability and economy of designs in life. Therefore, much emphasis must be placed on the efficacy for sustainability of the people to avoid risk of progressive collapse due to the instability of its nature after design. It is a challenge to curb the menace of inadequacy of design for the durability of concrete all day. The heterogeneity of concrete is real to be composed of Cement, Water (uncontaminated), Fine and Coarse aggregates otherwise known as constituent materials. The fossils lie embedded in a matrix of cement, water, fine and coarse aggregates and, are so strong because of the binding ability of the properties, absorbency in nature and most importantly, skilful knowledge of the designers during construction. The volume of concrete occupied by the coarse aggregates is significantly great compared to other properties thereby, playing the biggest role in terms of given desired strength re commended by different professional associations in the world. Concrete also is made up high compressive strength and a low value of tensile strength. It is used to protect corrosion of steel reinforcing bars. The importance to investigate concrete Elastic Modulus for various aggregate types as a parameter which enhances deformation resulting to cracks during serviceability with time is a course that cannot be undermined in the study of concrete properties. This implies that Elastic Modulus is a property that depends on compressive strength and aggregates stiffness. Strength and Stiffness are termed as the most probable important of all the properties of concrete materials considered for suitable structures design. The strength of a material obviously controls the estimation of the collapse load of a structure. Stiffness is important to ensuring un-deflection too much under load as well as dominates the avoidance of buckling of compression members. The characteristic strength of concrete is said to be classified based on designated concrete called strength class that depends on the types of constructions to be executed. When the value of compressive strength is too high there is a probability that most of the structures will be constructed of concrete possessing strength below this value and, too low a value will cause inefficient use of materials. So, it is the characteristic strength value of the cube strength at 28 days below which not more than 5% of the test out comes may be expected to depreciate is the primary concern of every designer at every point in time. The British Standards BS8110 indentifies the clause: The Strength, below which, not more than 5% of specimen will fail to signify strength that is very close to the mean value of a large samples of concrete normally distributed in a Bell-shaped against the frequency. This is idealized that some samples of concrete are stronger while others are weaker in strength and these variations are measure of the standard deviation. 1.20. PROPERTIES OF CONCRETE IN COMPRESSION The properties of concrete in compression are attributed to Short- term and Long-term loadings when discussing the linearity and un-linearity of the stress-strain curve. Short-term loading is used for Normal weight or density concrete and represented the most linear part called the elastic region of the stress-strain curve. The curve defines the uniaxial compressive test performed at normal, average speed on concrete at 28 days. The straight elastic portion describes how stress and strain are closely related before maximum stress is effective. Modulus of Elasticity is a derivative parameter resulting from the slope of this linear portion of the curve and is always larger in value when the strength of the concrete increases. The stress-strain curve shape varies considerably for identical concrete of the same cylindrical strength under the same loading condition and this strange behaviour depicts the variability in concrete samples due to one factor or the other from testing procedures : Nilson, Darwin and Dolon (2004:40). Long-term loading is the creeping nature of concrete with time. This is the continuous loading of concrete beyond 28 days of aged. The deformations of concrete are practically observed at this point in time which are proportional to the magnitude of the stress. At this region on the stress-strain curve, the stress is not longer linear. In addition to the load level, creep depends on the average humidity which is an important parameter to be investigated when designing a concrete. 1.30. THE REVIEW OF OTHER WORKS Based on the review of others, the Magazine of concrete Research(1991), Kaplan revealed that concrete with the same compressive strength may have different dynamic modulus of elasticity of different aggregates. The British Standard Institute CP110, and European Code; model code for concrete structures whereas made no provision but grossly looked at estimating compressive strength only. ACI Code tried in its little way to include a term for concrete density the expression for elastic modulus, since this term is raised to the power of 1.5, it has considerable weighting. But the BS110 has provided bases to satisfy new expressions for estimating the elastic modulus based on the work of Teychenne, to conform to the Stress-strain relationship of concrete such that: Ec28 = Ko + 0.2fcu28 BS8110, Ec28 = 5.5cu28 /à ¡Ã‚ µ) and Et /Ec28 = 0.4 + 0.6ft /f28 where, Ec28 = concrete elastic modulus at 28 days. fcu28 = characteristic concrete strength at 28 days. Ko = stiffness factor of aggregates (usually taken as 20Gpa, and 0.2 is a coefficient) by Teychenne but Code varying from 14 to 26Gpa. t = required age in days. And these expressions have functional relationship which the elastic modulus yields to at all points in time for consistency of analysis of the properties of materials. Hence, this project is only pivoted on the overall ideas and assumptions of the BS8110 to investigation the effects of four aggregate types (Granite, Gravel, Grey Limestone and White Polar Chippings) of the same size of 10mm, on compressive strength at 28 days. OBJECTIVES: To have a thorough justification by testing the effects of these four aggregates on the Elastic modulus of concrete to conform to the generalized approach of the BS8110 expressions. To critically compare and contrast the similarities or uniqueness between the experimental values of compressive strength targeted at 40-50N/mm2 of high strength concrete. To generally examine the aggregates stiffness in relation to Elastic modulus. Comparing compressive strengths of concrete in different proportion by volume of fine coarse aggregates of the concrete samples ( and in this case, 30:70% and 40:60% ratios is used) respectively. To verify the justification that the compressive strength of a cube is feasibly higher than the compressive strength of a cylinder when tested. CHAPTER TWO LITERATURE REVIEW 2.1.0. BACKGROUND Concrete as heterogeneous material is categorized into normal and light weight concrete based on the design performance relating the characteristic strengths and densities of materials to suit appropriate constructions. The high strength concrete is term generally used to mean concrete with a uniaxial compressive strength value greater than 41Mpa, as assumed by the ACI committee 363. This is used for the Design of columns especially of high residential structures, Bridge of longer spans, offshore oil platforms and so on: Nilson, Darwin and Dolan (2004:52). Higher Elastic modulus and coefficient of creep lower reduce long-term deflection in compression. The disadvantages include the reduction in ultimate strain capacity, brittleness in compression and increase the tendency of cracks to occur and not economical. The requirement is of low water-cement ratio below 0.25 according to Nilson, Darwin and Dolan (2004:53). low strength is otherwise known as conventional concrete having the str ength less than high strength concrete according to Bashir, Almusallam and Maslehuddin; In constructional and building Materials (2003: 97-103). High strength concrete is relative to a uniaxial compressive strength that is greater than that which is derived ordinarily in a region because maximum strength of concrete that is currently being produced varies considerably from one region to the other: Bahshir, Almusallam and Maslehuddin (2003:2). Hence, the using of high strength brings about the reduction of cross sectional area and dead loads in a structure. The functional mechanism of concrete depends on the overall constituent materials which are basically cement, water, fine and coarse aggregates in defined proportions with different properties resulting to characteristic strengths. The efficacy of a characteristic strength is attained only when the materials are properly selected, manufactured and designed, and the properties well defined and handled to yield desired result. Several investigators and researchers have revealed through their experimental works the influence of materials composite on the Elastic modulus and Compressive strength. Specifically, the Construction and Building Materials research (2002) and (2003). These respective Materials recognized that concrete should be properly examined as a three phase constituent materials of aggregates, cement and a transition between them. Also, that the transition zone is ranged 10-50 thick and generally seen as being the weakest component of concrete resulting to influence on the mechanical behaviour of concrete as could be compared to volumetric importance according to the Construction and Building Materials (2010:505-512). 2.2.0.THE DEFECTIVES OF HIGH STRENGTH CONCRETE (HSC). The problem of the High Strength Concrete as justified by the Construction and Building Materials (2003:3) is that cracking is more generalize and tends to homogeneous material characteristic as compared to the normal concrete: Bashir, Almusallam, Maslehuddin (2003:97-103). Also, High strength Concrete behaves as a linear elastic property and being subjected to brittleness than Normal concrete strength hence, cumulated that it is paramount to propound data on the mechanical properties of hardened concrete particularly, its strength in relation to the ideas of Bashir, Almusallam, Maslehuddin (2003:97-103); further argued that there is a good correlation between the Engineering properties of concrete such as stiffness factor. Generally, it is understood that besides the constituent materials, Mix design and Stiffness also play importance roles to enhance strength accumulation in concrete design. And the below flow chart may be used simply to illustrate how concrete is form from various materials including design mix to achieve desired strength and durability. DESIGN CONCRETE MATERIALS CEMENT, WATER, FINE AND COARSE AGGREGATES MIX-DESIGN PROPERTIES ( Strength, Workability and Durability ) Others Creep and Shrinkage Elastic modulus Fire resistance Resistance to abrasion Thermal conductivity Figure 1: Concrete Flow Chart 2.3.0. DESIGN MATERIALS There are basically three constituent materials of concrete for design purpose namely: Cement. Fine and Coarse Aggregate. Water. 2.3.1. CEMENT Cement as a design material is of various types but more importantly restricted to the Ordinary Port land type for the purpose of this investigation. It constitutes principally of chemical compound such as Dicalcuim and Tricalcium Silicates in different proportions by percentage. Cement fineness and soundness are the most properties of interest to be examined to achieve desired concrete strength according to the British Standard Institution (1991:20). It is believe that High Strength Concrete is resulting from high performance Ordinary Portland cement well ground in good proportion. The Cement paste helps to harden concrete to gain strength through a chemical reaction known as hydration property due to curing at 28 days age. It also mixes with water to fill the void of aggregates which enables the concrete to be easily placed and flows to avoid shrinkage. An Ordinary Port land Cement is one which all the particles will pass a No.100 sieve and over 95% will pass a No.200 sieve in British Standard (1991) and, must have minimum strength of (compressive strength) for 3-day mortal cubes of less than 15N/mm2, 7-day 23N/mm2 and 3-day concrete 8N/mm2 while, 7-day 14n/mm2, Kong and Evans (1996:20). Its weight is a function of the degree of compaction which is roughly taken as 1450kg/m2: Kong and Evans (1996). 2.3.2. AGGREGATES Aggregates are the most important constituent materials of concrete. These materials constitute about 65-75% by volume of hardened mass occupied in concrete mix thereby, constituting the highest quota of concrete strength. The High performance strength of concrete is due to the type of aggregates to be used in design. There are two main types known as fine and coarse aggregates. 2.3.2.1. Fine Aggregate This is natural sand from a good source free of impurities and contaminations that is capable of achieving the cohesiveness of the mix and desired strength: Kong and Evans (1996). Fine Aggregate is derived from natural sand or crushed stone sand or crushed gravel with particle capable of passing a 5mm sieve by Kong and Evans. A technically satisfied fine aggregate is one which has the capability of producing satisfactory concrete: Day (1999). It is said by Day to be standard and substandard if having the effect of retarding set, increased bleeding, excessive air entrainment, poor workability and increased water requirement, resulting in increase in shrinkage and extra cost. Most importantly, the features of a fine aggregate that affect the functionality of a design concrete has been identified by Day (1999): (i). Grading. (ii). Particle shape and surface texture. (iii). Clay. (iv). Chemical catalysts (salt and alkaline). (v). presence of mechanical weak particle. (vi). Water absorption level. (vi). source. However, this investigation only discus on the effect of Grading, Particle shape and texture, and more importantly source of the aggregates. 2.3.2.2. Coarse Aggregates . The properties of a coarse aggregate rely on solely the source of basic rock, the crushing process and its treatment in terms of separation into fractions, segregation and contamination as proposed by Day (1999). It is also noted that a coarse aggregate is one which is derived crushed stone, crushed gravel that can retain on a 5mm sieve according to Kong and Evans (1996). One important feature of a coarse aggregate is the bond characteristic usually associated high strength concrete which flexural and tensile strength are of special consideration, and it is a composite nature of chemical effects of surface roughness, particle shapes, water absorption and cleanliness by Day (19990. Again, Kong and Evans (1996); propounded that the durability and chemical inert under expose condition is the most requirement of a coarse aggregate, and the size, shape and surface texture and grading are said to be physical requirements must be examined because these are characteristics which enhance the strength or weakness of concrete. 2.4.0. GRADING A durable concrete must be dense, and when fresh, good enough for compaction: Kong and Evans (1996). There are voids comprise of mixture of cement, water and fine aggregate in mortar and that which is slightly more than sufficient is recommended to fill the voids of coarse and, cement paste slightly more than sufficient also to fill the voids of fine aggregate: Kong and Evans (1996). The voids are seen as functions of grading and particle size distribution by Kong and Evans. Generally, grading is the total way of accessing or categorizing the fineness and grade to which workability of concrete can be achieved considerably at a good flow. This is carried out through a comparative idea of sieve analysis as well as particle size distribution based on the recommendation by British Standards or ASTM of sieve sizes. These sieve sizes are used to estimate the cumulative percentage of finer of the weight retained particles on each sieve. And to comply with the BS 882, the percentages for the coarse aggregate and fine aggregate should fall within the limit the below tables: Kong and Evans (19960). Table2.10 Grading Limits for Coarse Aggregates Percentage by weight passing the standard sieves Nominal size of Aggregates Standards sieve (mm) 40mm to 5mm 20mm to 5mm 14mm to 5mm 50.0 100 37. 90-100 100 20.0 35-70 90-100 100 14.0 90-100 10.0 10-40 30-60 50-85 5.0 0-5 0-10 0-10 Kong and Evans (1996:36) Table2.20 Grading Limits for Fine Aggregates Percentage by weight passing the standard sieves Additional Limits for Grading Sieve Overall Limits C M F 10.0mm 100 5.0mm 89-100 2.36mm 60-100 60-100 65-100 80-100 1.18mm 30-100 30-90 45-100 70-100 600mm 15-100 15-54 25-80 55-100 300 5-70 5-40 5-48 5-70 150mm 0-15 0-15 Kong and Evans (1996:36). The above tables show that especially, the fine aggregate has zone division from coarse, medium and finer. The divisions are larger based on percentage passing the 600mm meaning in a fresh concrete mix, the content of the fine aggregate penetrating has an advantage over workability. 2.5.0. THE CONTENT AND PARTICLE SIZE DISTRIBUTION In the Construction and Building Materials (2010:505-512); Meddah, Zitouni and Belaabes used the effect of content and particle size distribution of coarse aggregate on the compressive strength as a base for argument of concrete strength. This revealed that several properties of aggregate such as degree of weathering, specific gravity, hardness, chemical, and mineral composition, shape, roughness, physical and chemical stability and pore structure are connected to the parent rock. Also, that adequate proportion of granular fractions depend on the type of concrete targeted and thereby, used similar aggregates such as Limestone, Basalt, Diabase, Granite and Quartz of the sizes of 15mm and 25mm for comparison; and ascertained after experimentation that the great effect on the usefulness of aggregates is largely depends on the particle size distribution. Meddah, Zitouni and Belaabes (2010) came to conclusion that; The value of compressive strength of normal concrete increases with the maximum size of coarse aggregates. The content of the coarse aggregates has a great influence on the compressive strength of both normal and high strength concrete, and increase in compressive strength is succeeded. The advantage of the coarse aggregate grains distribution on compressive strength of High Strength concrete is significant as compared to the Normal concrete. The compressive strength is strongly connected to the coarse aggregates parameters such as content proportion of fine to coarse aggregate and grain distribution of concrete mixture. Furthermore, Kong and Evans (1996) also supports these arguments but emphasize that higher coarse aggregate sizes results to lower water/cement ratio to achieve reasonable workability and higher strength of concrete. The reduced water/cement ratio is been offset by the strong effect of the lower bond area at the interface of the cement paste and the aggregate and of the discontinuities caused by the large particles. 2.6.0. EFFECT OF AGGREGATE SOURCE Relative to the action of various aggregate types on concrete properties called Elastic Modulus and compressive strength, several researches have been carried out by different people to justify the boredom to study how the negative impacts are reduced considerably on concrete strength collective sources of aggregates. In the Magazine of Concrete Research of (1999:291-304); this work reported the applicability of the BS approach to a range of 13 different aggregate types from a source in South Africa that the strength of concrete depends not only on stiffness, particle sizes, shape and texture, mix design but on selected sources of the aggregates. The source of controls the physical properties such as Relative Density RD, Look Bulk Density LBD, and Consolidated Bulk Density CBD, water absorption and Coefficient of thermal expansion should be examined in addition. Thus, Alexander (1991:291-304) concluded the results of his experimentation after thorough comparison to others that different aggregates produce different compressive and Elastic Modulus depending on their sources of selection which should be free from contaminations such as sodium chloride or alkaline and, was strongly supported by Day (1999); that chloride content of aggregates collected from beach sand is contaminated than dredge sand from sea. This contamination cause efflorescence and higher shrinkage and utter the setting and handing rates of concrete. 2.7.0. WATER Water is necessary for the design of concrete since it enables the concrete to be properly mix the constituent materials together for compatibility. This design water should be free of contamination of sodium chloride, oils, alkalis and sugar which are catalysts to reduce the effect or workability of the constituent materials of concrete. The requirement for water testing has been provided by the BS3148 for concrete suitability. Suitable water of concrete is otherwise known as design water when the measured volume is enabled to be predicted by the idea of mix design. It is also known as consumable water or hygienic water is necessary in concrete cast to have the desired strength and, if water is suspected to be contaminated, it is advisable by the BS3148 to run or cast a series of test sample made of contaminated and hygienic water to enable the designer to predict its effect on concrete and made decision on the selection of minimum quantity or volume of water is required for optimum strength of concrete whereas, large volume of water gives low strength of concrete. Excess volume of water leads to loss of slump. Workability of concrete depends on the water content used for design when considering the water/cement ratio criterion of mix design. 2.80. PRACTICAL MIX-DESIGN The term Mix-Design is the ability or a medium of selecting good components of concrete known as binders that are normally accessed on batching by weight or volume. The major aim of mix design is to select the optimum ratio of cement, water and aggregates to achieve a concrete with desired strength, workability, durability and economy: Kong and Evans (1996:50). It is strongly emphasize by Kong and Evans that practical mix design are based on the free water/cement ratio as the most important factor and the water content to determine or influence the strength of concrete. The batching relative to weight is preferably important in design of concrete for desired strength, and the idea or process revolves round water/cement proportion for batching weight of concrete for conventional aggregates especially with a constant density in question. 2.8.1. Water- Cement Ratio In general practice of concrete technology, water/cement ratio is perhaps the most important emphasized parameter to be examined in design. The base point of a typical mix design is the proper placed value of the water/cement ratio. It is simply the ratio of water to cement in terms of weight: Kong and Evans (1996). Practical mix design methods engaged the free water/cement and water content which are the two required factors that influence the strength, durability and workability of concrete. In the calculation of the water/cement ratio only the weight of the free water is used amongst the overall water absorbed by the aggregates and, it is the total water less the absorbed water while, the water content is the weight of the free water per unit volume of concrete: Kong and Evans (1996:50). Kong and Evans emphasized that the establishment by an initial mixes otherwise known as trails batch or adjustments on site: supported by Day (1999). Both researchers re cognised that there are two basically main methods of mix design captured from the works of Road Research Laboratory, the American Concrete Institute and Department of the Environment DoE known as the Traditional and DoE mixes. The water/cement ratio is chosen for strength and workability at average of 28 days called the mean target strength relative to characteristic strength: value that exceeds by a suitable margin known as current margin. 2.90. DURABILITY/ PEAMEABILITY OF CONCRETE 2.9.1. Durability The ability of a concrete to achieve its purpose of design in service is very important in design. The parameters that influence the potential integrity of concrete is over estimated in terms of durability of concrete. The provision of appropriate workability, suitable cement, aggregates and water as major ingredients of concrete in accordance with given standard and codes of practice are the base line. The tendency of concrete to exhibit a free corrosive nature and, a maximum protection against external forms of attack is impinge upon the correct choice of materials and adequate proportions: Lydon (1983). Durable design concrete is stable and capable of withstanding all the environmental conditions to which it is exposed: Kong and Evans (1996:38). 2.9.2 Permeability Permeability of concrete is related to durability and it is the crawl at which water can pass through the concrete: Kong and Evans (1996:39). Low permeable enables the concrete to withstand the effects of weathering, rain and action of freezing and thawing exposed conditions. The permeability of concrete increase rapidly with amount of voids and water/cement ratio and, when the amount over influxes the strength of concrete reduces. It is advisable that permeability should not exceed 7% else, bound to be corrosion in case of reinforcement: Kong and Evans (1996). 2.10. CREEP PROPERTY OF CONCRETE. Creep is a property of concrete that depends on loading duration. When there is an increase in strength in concrete with age, it is said to be under creeping condition. Creep is not actually proportional to strength but inversely related and can be estimated provided the strength-age could be determined. This is generally relative to the creep values of specimen concrete mixes which is derived from loading to one-third of the cube strength at 28 days curing age: Kong and Evans (1996:30). The concrete is unlikely to be stressed beyond one-half of the cube strength and, the creep of concrete at specified period of loading is roughly estimated to be proportional to the stress by Kong and Evans. Different concrete of the same cement paste content would produce creep that is approximately proportional to the stress/ strength ratio. Desired strength unaffected by creep is determined with respect to the avoidance of long term loading duration of concrete. The rate at which creep increases d epends on the increase in temperature as a linear function and, at a value of 1% of the 15 oC creep for each degree Celsius: Kong and Evans (1996:31). Generally, aggregate-cement ratio, aggregate content, cement content and water content do not have any significant effect on creep but water-cement ratio and cement type influence the level of creep in concrete design. 2.11. SHRINKAGE PROPERTY OF CONCRETE The shortening in length or contraction of concrete as a result of absorption of water in the gel is related to dry shrinkage: Kong and Evans (1996:33). It is a physical property of concrete unlike creep of chemical influence. Aggregate content, fineness of cement, and temperature influence the level of shrinkage of concrete. Low shrinkage concrete contains non-shrinking aggregates like limestone Quartzite gravel, mountain limestone, blast furnace slag, dolomite, granite and so on: Kong and Evans (1996:35). While, high shrinkage is as a result of aggregates volume change on wetting and drying such as slate, sandstone, basalt so on. Both coarse and fine aggregates influence the level of concrete shrinkage more importantly and, shrinkage is been reduced by using various aggregates of high Moduli of Elasticity that are dense and hard. 2.11.1. Aggregates Shrinkage Mechanism In Concrete Aggregates do undergo change in volume because they contain some minerals in form of clay which swell up when absorbing water or dry out and shrink. During setting of concrete, the cement paste volume changes. Forces are exerted during setting on aggregates resulting in moisture content affecting the overall size of the aggregate. The total weight of aggregates is that which is related to Elastic modulus and the volume ratio of the cement paste. It is reasonable to say that all aggregates suppose to be shrinkable to a greater or less extent as well as change in volume for proper classifications and selections for high or low shrinkage types: Pike (1990). The effect of high shrinkage causes unwanted movement or cracks and reduction in durability of concrete thereby leads to corrosion of the reinforcement members. 2.12. CONCRETE STRENGTH The design strength is associated with Compressive strength of concrete which is the common measure for judging a standard durable concrete at 28 days curing age. Buildings and other Engineering structures are purely designed with the most performance estimate of the compressive strength for stability, workability and durability of concrete. In the National Ready Mix Concrete association (NRMCA:2003); compressive strength is generally regarded as a measure by breaking Cylindrical Concrete Specimens in a Compressive Testing Machine basically, based on the precepts of the BS8110 and ASTM. The estimation of compressive strength is derived from the failure load over the cross-sectional area that is resisting the load of unit of mega Pasca (Mpa); an International standard Unit of measurement: BS8110 (1985) and NRMCA (2003). Compressive Strength of concrete varies from 17-28Mpa. The compressive needs to be determined from a concrete mixture to attain the desired or required strength for sp ecified for a job. The strength tested results from cast concrete cylinder is used for quality control, estimation of strength or acceptance of concrete in

Acupuncture: Chinese Medicine Essay -- essays research papers

Acupuncture: Chinese Medicine As with all things we know little about there is quite a bit of mystery surrounding acupuncture. The part people see the most is a person with needles sticking out of their flesh. Understandably being wary of sharp pointed objects being wielded by a complete stranger, this is often an obstacle that needs to be over come. The best way to do this is by becoming educated about how acupuncture is performed, where it came from, what it does, some of the benefits vs. the problems, and the different views about it. Though out the many different texts on acupuncture you find there is room for interpretation on how to perform it, what to use, and even where the pressure is placed. One thing you will find in common among these texts is this, acupuncture works to varying degrees.   Ã‚  Ã‚  Ã‚  Ã‚  The earliest recordings of the use of acupuncture go back 2,000 years. In China it is widely expressed that it has been in use for 4,000 years. The origins go back as early as the Stone Age where abscesses were punctured by sharp stones or bone fragments. ( History ) When you experience pain it is an instinctive reaction to apply pressure to that location. Such as when you get a toothache. Also the body may experience pain where the infection is not localized. Your body naturally sends you warning signals that something is wrong. The Ancient Chinese utilized these warnings, and developed an intricate system of these points over time through observation. It is easy to infer that applying pressure to relive pain with your hands evolved into the use of needles instead.   Ã‚  Ã‚  Ã‚  Ã‚  Tortoise shells have been found and dated back to 1500 B.C. – during the Shang Dynasty - recording the use of acupuncture. The first actual written text acclaiming acupuncture is called Nei Ching Su Wen. It is written into two basic sections. The Su Wen, or easy questions and the Lung Shu, or hard questions. This book basically lays out all the different points, but it is mostly a book on concept and theory. The Nei Ching Su Wen lays the basic rules of philosophy and treaties on health. These philosophies branched form two mainstream religions that abounded during the Warring States period in Chinese history. The first is Confucianism. The teachings of this â€Å" religion â€Å" stress that the body is scared and are against dissection or surgery. T... ... You have no nasty side effect of drowsiness, or being groggy. The vomiting and stomach irritation are a thing of the past. This technique is especially being used and experimented with in China.   Ã‚  Ã‚  Ã‚  Ã‚  There is also another branch of acupuncture being explored. It involves pressure points specifically I the ear. These points are being found to be connected to all other organs of the body. Although there are arguments that acupuncture is purely suggestion, they can be proven wrong. Suggestion cannot allow for a human being to under surgery with pain. The discovery of endorphins shows that a chemical process is instigated through pressure points. There is a chemical increase of endorphins when acupuncture is performed. Research being funded in China by the United States, and other Western countries, are going to lead us to a great break through some day. The future looks bright, and everyday we learn more and more. Some day we may learn the secret of why acupuncture works for now we will have to accept that it does work and try to combine old and new philosophies to reach a greater understanding.   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  

Fanons The Wretched Of The Earth and Foucaults Discipline and Punish :: Wretched Of The Earth Essays

Fanon's  The Wretched Of The Earth and  Foucault's Discipline and Punish Fanon's book, "The Wretched Of The Earth" like Foucault's "Discipline and Punish" question the basic assumptions that underlie society. Both books writers come from vastly different perspectives and this shapes what both authors see as the technologies that keep the populace in line. Foucault coming out of the French intellectual class sees technologies as prisons, family, mental institutions, and other institutions and cultural traits of French society. In contrast Frantz Fanon (1925-1961) born in Martinique into a lower middle class family of mixed race ancestry and receiving a conventional colonial education sees the technologies of control as being the white colonists of the third world. Fanon at first was a assimilationist thinking colonists and colonized should try to build a future together. But quickly Fanon's assimilationist illusions were destroyed by the gaze of metropolitan racism both in France and in the colonized world. He responded to the shattering of his neo-colonial identity, his white mask, with his first book, Black Skin, White Mask, written in 1952 at the age of twenty-seven and originally titled "An Essay for the Disalienation of Blacks." Fanon defined the colonial relationship as one of the non recognition of the colonized's humanity, his subjecthood, by the colonizer in order to justify his exploitation. Fanon's next novel, "The Wretched Of The Earth" views the colonized world from the perspective of the colonized. Like Foucault's questioning of a disciplinary society Fanon questions the basic assumptions of colonialism. He questions whether violence is a tactic that should be employed to eliminate colonialism. He questions whether native intellectuals who have adopted western methods of thought and urge slow decolonization are in fact part of the same technology of control that the white world employs to exploit the colonized. He questions whether the colonized world should copy the west or develop a whole new set of values and ideas. In all these questionings of basic assumptions of colonialism Fanon exposes the methods of control the white world uses to hold down the colonies. Fanon calls for a radical break with colonial culture, rejecting a hypocritical European humanism for a pure revolutionary consciousness. He exalts violence as a necessary pre-condition for this rupture. Fanon supported the most extreme wing of the FLN, even opposing a negotiated transition to power. His book though sees the relationship and methods of control in a simplistic light; he classifies whites, and native intellectuals who have adopted western values and tactics as enemies.

Language & state of chaos Essay

The lexical choices made by Beckett in the first act show many things, such as the relationship between Estragon and Vladimir, and the confusion of the characters as to the time and the meaning of their actions. The main characters, Estragon and Vladimir, switch roles continually, so not using language as an expression of their selves, therefore the words used show no badge of identity. This shows interchangeability in the characters, so keeping the audience searching for the characters’ own distinctive personality. This role switching that not even the characters’ roles/ personalities are certain. This confusion is increased with the characters’ inclination to talk in adjacency pairs like they are both speaking from the same train of thought To say that the language is in a state of chaos suggests there is utter confusion in the play, the audience can hear and understand the individual words being said, but cannot put them into a relevant context or meaning. This ‘chaos’ is seen frequently throughout Vladimir and Estragon’s conversations; although taking turns with one another while speaking, they do not engage in a conventional conversation, one character talks about one topic, while the other talks about a different subject all together. The first moment I have chosen reflects this chaotic language; the two characters talk about the bible, beginning in conventional adjacency pairs, Vladimir: â€Å"Did you ever read the bible? † Estragon: â€Å"The bible†¦ I must have looked at it† but then the conversation starts to waver on Estragon’s part – Vladimir: â€Å"Do you remember the story? † Estragon: â€Å"No. † Vladimir: â€Å"Shall I tell it to you? † Estragon: â€Å"No. † And finally, the language and conversation between the two becomes chaotic – Estragon: â€Å"Saved form what? † Vladimir: â€Å"Hell. † Estragon: â€Å"I’m going. † This deterioration in the exchanges between the two characters shows the pettiness of them both; they seem to squabble about anything, no matter how inane it seems to the audience. This can be seen as due to the lack of meaning or activity in their lives, with them using any method of keeping boredom at bay. This interaction between the two characters shows their abuse of Grice’s maxim of relevance, as one character’s speech holds no relevance to that of the other’s. In this moment in the play there is a lot of uncertainty for both the characters and the audience, which Beckett creates mainly via the language used by the two main protagonists. The characters are unsure about what the other is talking about, Estragon: â€Å"Who? † Vladimir: â€Å"What? † Estragon: â€Å"What’s all this about? â€Å", and they are also uncertain of what really happens in the bible, Vladimir: â€Å"But all four were there†¦ why believe him rather than the others? † The audience is made uncertain of the meaning of the character’s talking about the bible, it is near the start of the play so they do not know what is to come. My second moment is different form my first as Estragon and Vladimir are now joined by two passing characters, Pozzo and Lucky, although Lucky does not speak till later on in their meeting. Pozzo speaks of how much pressure Lucky, his knook, puts on him, this is all an act on his part, but Estragon and Vladimir believe him, they repeat Pozzo’s words to add definition and to show their feelings of sadness towards him, Pozzo: â€Å"It’s terrible†¦ he must go†¦ I’m going mad†¦ I cant bear it†¦ any longer†¦ † Vladimir: â€Å"He can’t bear it. † Estragon: â€Å"Any longer. † Vladimir: â€Å"He’s going mad. † Estragon: â€Å"It’s terrible. † This makes Estragon and Vladimir look rather naive as they believe Pozzo straight away and accuse Lucky of ‘crucifying’ Pozzo, but are then told by Pozzo that he was lying. Estragon and Vladimir’s language in this moment is still chaotic, repeating themselves and each other, and showing confusion at what each other said, using the word ‘what’ several times as a response. Their ‘adjacency pairs’ are jarred and do not seem to fit together, Vladimir: â€Å"I don’t think so† Estragon: â€Å"What? † Vladimir: â€Å"I don’t know† Estragon: â€Å"Ask him†. They then go on to talk mundanely about the evening, which turns into babblings of irrelevant words, Vladimir: â€Å"Worse than the pantomime. † Estragon: â€Å"The circus† Vladimir: â€Å"The music-hall. † Estragon: â€Å"The circus† This is an example of their words and thoughts reflecting a single unit, as if it were just one person speaking, showing their relationship to be so close they are starting to think alike. This chaotic language also reflects the uncertainty theme, which runs through the play, shown through the character’s lexis and actions (seen in the secondary text). This chaos is shown when Pozzo appears to have lost his pipe, Estragon says â€Å"He’s a scream. He’s lost his dudeen. † This is a word coined by Beckett which does not seem to have any meaning, showing how Beckett uses language to confuse the audience, as it seems slightly ridiculous how Estragon makes up a word purely to rhyme with ‘scream’. The chaotic language in the play seems mainly on a humorous level, for example, in the second moment chosen Vladimir rushes off to relieve himself, while doing this Estragon shouts â€Å"end of corridor on the left†, even though both the characters and audience are aware they are in the middle of nowhere with just a tree. Both of the moments chosen show language to be in a state of chaos, thus supporting the opinion that nothing is certain in the play, although there are certain factors that make this statement debatable which should be taken into account, for example, Vladimir and Estragon’s relationship, they have known each other for a long time as they share memories etc. It can also be said that the certainty of some topics in the play is left up to the audience to understand, through the situation and the characters.
