Bill Bowerman once said, The real purpose of running isn t to win a race, it s to test the limits of the human heart. That was the quote that was running through my mind as I kept in pace with my best friend Tyler, the sounds of our jogging almost rhythmic. The cool afternoon air cleared my busy mind, and as we rounded the corner of the park s running trail, out stopping place near the duck pond came to view. Beside me, I heard a sharp intake of breath come from Tyler, signaling that he too had seen the pond. Without a second thought, we both sprinted towards it. The path blurred below me as I felt a surge of adrenaline. I willed my muscles to push harder and welcomed the burning sensation that coursed through my body. My heart pounded to the steady thumps of our footsteps hitting the cold rocky ground. I felt the beads of sweat running down my forehead and the nape of my neck making my hair to cling to it. As I was reaching the end, a new burst of energy erupted in me, throwing over the finish line. I hunched over trying to catch my breath as I held onto a bench that faced the pond. My throat burned as I laughed at the sight of him cursing and kicking the dirt. I reached into the pockets of my shorts and tossed him a set of keys to which he caught flawlessly. Without saying a word, he turned and began on his journey back. I gathered what little energy remained in my body and forced myself to sit down knowing it would take him some time to reach the parking lot.

Essay on Offshore Drilling - 3083 Words

Offshore Drilling What is it? Drilling for oil in the ocean is one of the greatest technological breakthroughs in recent decades, and many new techniques have been developed to profit from the abundance of oil underneath the ocean floor. While drilling for oil has been around for hundreds of years in one form or the another, the effective extraction of petroleum from beneath the sea floor did not surface until the last forty years. The search for oil often turns out to be unproductive, but this practice is vital for the economic future of many nations. In order for any drilling to take place, an offshore drilling rig must first be installed. These offshore platforms can be situated in water up to a several hundred meters in depth.†¦show more content†¦These production platforms come in a variety of sizes, shapes, and types, which are dependent on the dimensions of the field, the depth of the water and how far the oil and/or gas field is from shore. The platforms are generally made of steel and fixed to the seabed with steel posts. These platforms harbor all of the processing equipment for the well and can house a maximum of 80 workers. In addition, platforms have concrete structures large enough to store oil, with gravity keeping them situated on the seabed Explanation of Drilling Drilling begins once the drill bit is lowered to the ocean floor. This first step is referred to as spudding. There are two types of drill bits: (1) a roller cone or rock bit which usually has three cones armed with steel or tungsten carbide teeth or buttons; or (2) a diamond bit, imbedded with small industrial diamonds. The drill bit is attached to drill pipe and rotated by a turntable on the platform floor. As the hole deepens, extra lengths of drill pipe are attached. (Offshore Drilling) The diameter of the drill bit varies from a diameter of 36 inches, which is used when the hole in the ocean floor is first started, to a diameter of 8.5 inches. The total length of a drill pipe is 30 feet. The time it takes for the drill to reach the oil and gas trap could be weeks.

Abstract Overstock.com, also known as O.co, with headquarters in Salt Lake City, Utah was founded in 1999 by Patrick S. Byrne, its CEO and Chairman of the Board of Directors. Byrne recognized the potential in liquidating excess inventory through the Internet. Up until then, consumers had relied upon outlet centers with crowds and limited product selections for finding bargains, and small retailers found little access into the world of closeout merchandise (O.co, 2010). Meantime, the art of online shopping seemed to be skyrocketing. In 1999 Overstock.com reported a $1.8 million in annual revenue to over $1 billion in revenue in 2010.

Child And Family Studies - 1039 Words

In the Journal of Child and Family Studies, Tavassolie, Dudding, Madigan, Thorvardarson, and Winsler researched how perceived parenting styles between mothers and fathers can impact children behaviors as well as conflicts within the marriage. How two parents perceive the other partners parenting can cause issues in the marriage as well as how the kids handle it. The kids also react differently to parenting styles and this can impact their behavior. In the summary I discussed how Nick and Melissa parent their children. Melissa has more of an authoritarianism style, while Nick has more of a permissiveness style.

A set of questionnaires were given to the participants to complete. These included The Parenting Styles and Dimensions Questionnaire (PSDQ), Preschool and Kindergarten Behavior Scales (PKBS), The Child Behavior C hecklist (CBCL), The Conflicts and Problem- Solving (CPS), and The Short Martial Adjustment Test (SMAT). The results from the research included that as mothers and fathers self-reported parenting styles differed more from each other, martial conflict increased (Tavassolie et al. 2016). In correlation to parenting styles and child behavior, the only significant relationships found were that parents self-perceived permissiveness increased, child externalizing behaviors also increased (Tavassolie et al. 2016). Child behavior problems are also affected on how the individual parent perceives their own parenting style. â€Å"In general, as reported differences between the perception of one’s own parenting style and the perception of the spouse’s style increase, so do most behavior problems† (Tavassolie et al. 2016).

A primary method for counting the visitors involves hiring human auditors to stand and manually tally the number of visitors who pass by a certain location. But human-based data collection comes at great expense. Here is a low-cost microcontrollerbased visitor counter that can be used to know the number of persons at a place. All the components required are readily available in the market and the circuit is easy to build. Two IR transmitter-receiver pairs are used at the passage: one pair comprising IR transmitter IR TX1 and receiver phototransistor T1 is installed at the entry point of the passage, while the other pair comprising IR transmitter IR TX2 and phototransistor T2 is installed at the exit of the passage. The IR signals from the IR LEDs should continuously fall on the respective phototransistors, so proper orientation of the transmitters and phototransistors is necessary. circuit description Fig. 1 shows the transmitter-receiver set-up at the entrance-cum-exit of the passage along with block diagram. Two similar sections detect interruption of the IR beam and generate clock pulse for the microcontroller. The microcontroller controls counting and displays the number of persons present inside the hall. Fig. 2 shows the circuit of the microcontroller-based visitor counter, wherein the transmitter and the receiver form the IR detection circuit. Control logic is built around transistors, operational amplifier LM324 (IC1) and flip-flop (IC2). When nobody is passing through the entry/exit point, the IR beam continuously falls on phototransistor T1. Phototransistor T1 conducts and the high voltage at its emitter drives transistor T3 into saturation, which makes pin 3 of comparator N1 low and finally output pin 1 of comparator N1 is high. Now if someone enters the place, first the IR beam from IR TX1 is interrupted and then the IR beam from IR TX2. When the beam from IR TX1 is interrupted, phototransistor T1 and transistor T3 cut-off and pin 3 of comparator N1 goes high. The low output (pin 1) of comparator N1 provides negative trigger pulse to pin 1 of J-K flip-flop IC2(A).

The negative-going pulse is applied to clock pin 6 of IC2(B) when the person interrupts the IR beam from IR TX2. There is no change in the output of IC2(B) flip-f lop. This triggers the external interrupt INT0 (pin 12) of microcontroller AT89C52. The AT89C52 is an 8-bit microcontroller with 8 kB of flash-based program memory, 256 bytes of RAM, 32 input/output lines, three 16-bit timers/counters, on-chip oscillator and clock circuitry. A 12MHz crystal is used for providing clock. Ports 0, 1 and 2 are configured for 7-segment displays. Port-0 pin is externally pulled up with 10-kilo-ohm resistor network RNW1 because port0 is an 8-bit, open-drain, bidirectional, input/output (I/O) port. Port-1 and port-2 are 8-bit bidirectional I/O ports with internal pull-ups (no need of external pull-ups). Port pins 3. 0 and 3. 1 are configured to provide the set pulse to J-K flip-flops IC2(A) and IC2(B), respectively. External interrupts INT0 and INT1 receive the interrupt pulse when the person interrupts the IR beams. Resistor R9 and capacitor C5 provide power-on-reset pulse to the microcontroller. Switch S1 is used for manual reset. When the microcontroller is re- set, the flip-flops are brought in ‘set’ state through the microcontroller at software run time by making their ‘set’ pin high for a moment. The value of the counter increments by Fig. 5: An actual-size, single-side PCB for the microcontroller-based visitor ‘1’ when the counter (Fig. 2) including its power supply (Fig. 3) interrupt service routine for INT0 is executed. The output of the corresponding J-K flip-flop is set to ‘high’ again by making its ‘set’ input pin low through the microcontroller. The micro-controller is configured as a negative-edgetriggered interrupt sensor. Similarly, if somebody exits the place, first the IR beam from IR TX2 is interrupted and then the IR beam from IR TX1. When Fig. 6: Component layout for the PCB the beam from IR TX2 is interrupted, output pin provides clock pulse to pin 6 of J-K 7 of comparator N2 goes low.

Master of Teaching Enhance Skill

Question: Discuss about theMaster of Teaching for Enhance Skill. Answer: Introduction The main aim of the report is to identify the how professional learning can be used to support student learning. The main may is to identify how professional degrees can be used to improve the students learning and knowledge in class. Teachers are the most essential part of the students life and without teachers it is not possible to gain knowledge that is required by students to enhance skill and talent that student posses. Through the evidence gathered the report identifies the learning needs of the student. The author uses the literature review to support its argument. It identifies the various learning needs of students below standard eight mathematics class. There are various teaching stratifies that the teachers can use to develop and improve the knowledge that the students possess and improve the learning ability. The survey was done on the class of twenty girls who were studied in class 8 that came from different cultural backgrounds. The class consists of mixed range of stud ents with physical disability, and diverse learning abilities. Three students have moved to Australia from china. These students have very good mathematical skill but they struggle with literacy and other subjects. The report identifies the literacy in mathematical classroom and identifies how the teachers knowledge and professional degree can improve and support students learning. There are various learning needs to improve the students mathematical knowledge and literacy. The main identified common learning need is improvement in literacy help. The most common problem with the student who has moved from china to Australia is with the literacy knowledge of mathematics (AAMT, 2014). Body The students in a class come with different background culture and know different languages. The major problem with students coming from different countries or places is that the languages known to them are different. To understand the mathematics terminology and words it is essential for the students to know the language that is used in class or the most common language that is English. Mathematics is not only about equations and calculations. It has various terms that require students to have literature knowledge and for this the students needs literacy support. There are wide range of learning needs that are identified that include wide diversity of students, low literacy, inability to retain and recall information, and learning disabilities that can be the reason for low literacy and numeracy. There are many strategies and actions that can be used to meet these learning needs and assist students to maximize their learning (Cooper et al., 2014). The common problem identified for the majority of students is the low literacy skills. The evidence shows that the students often misinterpret the words that are used in mathematics that often lead them to take out the answer that are wrong. Evidence shows that the students have mathematical knowledge but it is due to the lack of literacy skills that creates more problems. The survey conducted showed that the students were given a sum that included least word in it which the students misinterpreted. The survey showed that the students who moved to Australia from China also had the problem of low literacy skill. The other problem that students also have is lack of motivation to learn mathematics and taking up new challenge to solve them (Alderman, 2013). These three students mathematically are well ahead of rest of the class buy they struggle with mathematical terminology and worded mathematics problem. Due to lack of literacy skills students are unable to give proper title for the gr aphs in the assignment due to which they often loose marks. Giving inaccurate answer also goes against literacy continuum strand. The evidence shows that not all students lack literacy skill to interpret the mathematical results. Some of the students have profound mathematical knowledge along with good literacy skills. They are the ones who can interpret the mathematical results well and also give appropriate graph title as the result from the evidence shows (Brophy, 2013). There are various strategies that can be implemented by teachers to address and highlight the issue of low literacy skills in students especially for the ones who come from different background and countries. Literacy skill is the most essential, skill that the students should have. If the students do not have the knowledge for what variable should the problem be solved then the problem arises not only for the students but also for the teachers that teach the subject. The issue is serious in case of mathematics because misinterpretation of even one word in the sum will give the wrong result. Hence it is essential for the schools and teachers to solve the problem and improve the core standards of literacy skills in students (Cooper et al., 2014). The teachers should give special emphasis to the students who are migrant from China and has come to Australia to gain knowledge. The teachers or the professionals can arrange for special classes or extra hours to teach and solve the problems that students face in case of literacy skills. The lessons that the teacher plans to teach in one particular class should be planned. The teacher then should give few extra minutes to go over vocabulary and make the students add the basic terminology and words that are being used for the particular problem (Tomlinson, 2014). This will help the students on understanding the basic terminologies and words that will be used in the lesson. Teachers should assist students to decode the questions. Harsh rules should not be implied on students specially the ones who are not acquainted with the language that is being used. They should be given an opportunity to use alternative formats for assessing the task unless they are able to fully develop the liter acy skills that are acceptable (Kolb, 2014). Proper interaction and communication with students is also one of the strategies that can be used by the professionals to support the learning needs. The teachers are the ones that create a comfortable environment for the students. It is the responsibility of the teachers to make the students feel safe to work in groups so that the students can raise the problem freely and interact with the teachers. The teachers should interact with the students and know the problems that they face. Individual attention should be give to the ones who are poor in development of literacy skills especially to the students who have come from china. This provides students with an opportunity to use mathematical vocabulary language in class which will over time benefit their literacy skills. It is also essential for the teachers to know the students background in order to teach them and understand their problem (Laurillard, 2013). Many students also lack motivation to take up new challenge. In this case it is essential for the teachers to motivate the students by creating a new learning experience and making the vocabulary more interesting. New ways of teaching should be adopted by teachers to make the lessons more interesting. Students also face with the problem of inability to retain the lesson learned in class for long period of time. It is essential concern as learning and retaining the lessons is the key to success. The surveyed showed that students were unable to answer the questions that were asked the very next day from the chapter being taught. For example if the problems on graphical solution was taught on day one and if the students were asked questions based on that on day two the result showed that the students failed to recall the concepts (Moon, 2013). There are many strategies that can be used to solve the problem of retaining and recalling the concepts taught in class. These include state-dependent recall, done by making connections with what students are learning to something such as various rooms, objects or information that help in the recalling process. Another strategy is chunking, rather than remembering individual information, chunking it up by connections makes it easier to retain and recall. Spaced repetition suggests that it is important to increase time intervals between subsequent reviews of previously learned material. So revision of the previous lesson in the first few minutes of every lesson has proven to enhance student learning and understanding (Van et al.,2013).This can be done by simple techniques such as asking questions and through peer discussions. The students who have problem in retaining and recalling information should be given the experience of visual aid so that they dont have problem in retaining the information and concept. Proper notes should be given to students so that they can go home and revise the concepts in order to retain the solution. Proper instructions should be given to students stressing the main ideas for the lessons. It is essential for the teachers to have good knowledge of the subject that they teach. Without the knowledge of the subject the teachers wont be able to make the ideas that they want to convey (Silver, 2013). Research Questions The main aim of the report is to discuss and examine the following research questions: How can the professionals support the students learning needs and develop the literacy skills to improve the mathematical knowledge? What is the effect of increasing the literacy focus on word problem solving skills in a grade eight mathematics class? Literature Review Many concepts are there to explain the concepts of development of literacy skills in mathematical knowledge. Literacy focus refers to the challenges that the linguistics have in learning mathematics. These include the English terms that are used in mathematics such as least, maximum and other linguistics. It also includes understanding proper mathematical terminologies such as trigonometry, compound interests, annuities and others (Race, 2014). Word problem also known as problem solving refers to the mathematical problems or questions expressed in terms of hypothetical situation explained in terms of paragraphs or sentences. Word problem is theoretical explanation of mathematical questions. It is essential for the students to be efficient in both English and mathematics in order to solve the word problems. It is essential for the students to have ability to translate the sentence or the paragraph into mathematical equations to solve the problem. For this the students must be efficient in both English and mathematics (Brown Chandrasekaran, 2014). The main aim of discussing this section of the report is to identify the issue of linguistics in teaching and learning mathematics that faces English as an additional language. Within a mathematic classroom, particularly during the senior years, linguistic issues are predominantly encountered in word problems (Whimbey et al.,2013). It is also essential to identify the most difficult component of mathematics that is word problems. The review investigates a range of Australian and international policies, research findings and articles; to evaluate the significance of the issue that is considered general from students and teachers perspectives. In addition, strategies and practices that could help students overcome linguistic barriers and improve word problem solving skills are gathered (Hopkins, 2014). The Significance of Issue The main issue of linguistic challenge arises is due to diversity of students. These are the students that need additional help in English in developing literacy skills. These are the students that come from another country such as Australia to learn and study. Since the Australian language is different from Chinese it is essential for these students to understand the linguistic in which the theory is being taught in class. Before a student can apply the trigonometric knowledge to calculate the answer to the word problem it is essential to overcome the challenges from both English and the language of mathematics; for example angle of depression, trigonometry, and other word problems and concepts. As a result, the students of class eight are targeted in order to uncover educational approaches and strategies that could help these students overcome the challenges of word problems during their senior years (Earl, 2012). From Students Perspective The linguistic learning need relates to students who are struggling to simultaneously deal with the difficult mathematics subject content, the language of mathematics and the topical English language. Developing literacy skills helps the student get a clear picture of mathematical knowledge (Xin et al., 2005). Mastering the language of mathematics involves shifting from everyday reading, writing and informal ways of construing knowledge into subject-specific, technical and academic ways that are necessary for disciplinary learning in mathematics. The main issue that hinders the growth of the student in the class is the differences in the linguistics knowledge and value (DuFour Marzano, 2015). Strategies and Practices that Help Learning and Teaching Language in Mathematics Classrooms The study shows that it is essential to encourage students to work cooperatively with each other in a group so that they get new ideas and knowledge to learn and develop literacy skill. It is also essential to teach students for conceptual understanding and develop childrens procedural literacy. It is also essential for the teachers to promote strategic competence through meaningful problem solving investigation. The teachers should have ability to demonstrate acceptance of students divergent ideas. The teachers and the professional should also have the ability to influence learning by posing challenging and interesting questions. It is also essential for the teachers to motivate students to take new challenges. The teachers should also believe in their students that they will be able to do mathematics and solve the problem. Mathematics is not magical or mysterious in nature (DuFour DuFour, 2013). The students should take up the challenge of solving the problems. Practice makes the man perfect. So it is essential for the students to practice the questions effectively at home. It is also essential for the students to be able to manipulate the results and use various representations to communicate the mathematical knowledge and ideas. It is essential for the teachers to make the theory and literature more innovative such as using color tiles to build in term a sequence and working in groups. The professional learning continues evaluating texts and strategies evaluating a personal interpretation of a text critically (Buehl, 2013). Conclusion Developing professional learning to develop literacy skills and learning is essential in order for the development of students knowledge. Fostering mathematical skills require a rich and healthy environment. It is not only essential to develop mathematical skills but it is also essential to understand the problems and transform it into mathematical equations. For this the student requires a great literacy skill and linguistic understanding. The main learning needs that hinder the growth of students are the lack of motivation, lack of power to retain and recover the concept, and lack of literacy skills. The teachers can formulate strategies to develop the literacy skills. Students diversity is the main issue due to which it is essential for the teachers to develop the literacy skills.
