Martial Arts Essay -- essays research papers
Martial Arts When you think of martial arts, what comes to mind? The slow, calm movements of Tai-Chi Chuan or maybe the faster, hard movements of Karate or Tae Kwon Do. No matter what you think of it always contains practiced movements of the body and a lot of concentration. These two elements combined with spirit and patience is basically what martial arts consists of. Martial arts is so great because it strengthens each of these aspects of body and mind to make a beautiful display of movement. This has attracted many people to all kinds of martial arts and with the help of the movies made it very popular among Americans. Today, many Americans prefer martial arts as an exercise to help them stay in shape. Tai-Chi, as an example, is a great martial art because of its use of both the body and mind. Tai-Chi canââ¬â¢t be done correctly if the person is not relaxed and doesnââ¬â¢t know the movements being done very well. The basis of Tai-Chi Chuan derives from the idea of being constantly round when performing it. If you are attacked on a straight line and you resist on a straight line, the stronger force will win, but if the incoming force is neutralized by circularity, then it becomes easier to defeat your opponent, no matter how strong they might be. Thatââ¬â¢s what Tai-Chi is based on, but It takes years of practice to get any good at it and decades to master. Another example of martial arts is Koreaââ¬â¢s Tae Kwon Do. The main differences between Tai-Chi and Tae Kwon Do is the uni...

Academic Success Essay
A lot of students think that learning is only in class. If students use two extra steps, most students will not forget what they learned in class. To achieve effective learning, students needed to follow two extra steps in the three strategic learning processes. The key to success is by following these three strategies. Review is essential to student success. Unless content is reviewed by students shortly after it is learned, it will soon be forgotten. To avoid forgetting what you learned, it is recommended to review daily. It is also recommended to reduce large volumes of notes into point form and to paraphrase what you have learned. Other helpful tips include creating concept maps and diagrams; creating fact, concept or vocabulary cards and using visualization to better connect to what you learned. These are all important tools to helping students better understand and memorize lesson content. The key to achieving academic success cannot be directly correlated to one specific area. Rather it requires students to be overall rounded in many different aspects. This includes attending class regularly to keep pace with the class. Falling behind in studies or homework can be detrimental to academic success and can induce stress onto students. Participating in class activities and discussions are also vital parts of learning and applying concepts learned. On the other hand, taking good, concise notes will always help in the long run when reviewing for tests and exams. To sum it all up, strategic learning is the password for many academic achievements. Being exposed to knowledge is the first step in the journey, the fact that young scholars can learn and be a part of history is a phenomenal step in furthering their search to success. Reviewing notes, in the way the young individual wishes, by him/herself, or with a good friend, this will help him/her to understand what has been learned in a way s/he understands. Lastly practice is a great way to memorise what has bee n learned, when practice achieves its full potential, the individual wonââ¬â¢t only be entitled for a good mark, but also a way to view, under & think of things. Those three attributes will help scholars become more successful, but itââ¬â¢s important to one as it is to the other, and each and every person should find the learning strategies effectual for him/herself, and in extremely exceptional occasions even invent or innovate new strategies. Academic Success Essay Answer each question below in at least 75 words per question, reflecting on your current abilities, and identify resources to strengthen your skills. Refer to the videos, readings, and other weekly assignments to help you compose your answers. Question Your reflection How would you define academic readiness? See more: Examples of satire in adventures of huckfinn essay I would define academic readiness as being ready,willing and able to let yourself learn.Having the mindset to be ready to take on one of the hardest obstacles of your life.Learning new things doesnââ¬â¢t come easy to everyone.Especially me. I graduated high school 16 years ago,and vowed to never continue my education because I was scared and had low self-esteem.I learned over the years that I can do things,even if its hard or uncomfortable,if I set my mind to it.I am ready,academically,and personally to learn and to achieve my goals,because I need to be and deserve to be. What concerns, if any, do you have with academic writing and reading? Iââ¬â¢m concerned mainly with writing essays.Since its been many years since Iââ¬â¢ve had to write anything lengthy or of any real importance,Iââ¬â¢m not very confident about it.I am,however,confident in my spelling and reading skills.I am looking forward to developing new skills in writing and learning how to put a good essay in order ,since there are many resources available to help me. What two university resources will you use to strengthen your writing and reading skills (refer to your Student Resources Worksheet)? The first resource I will be using is the Center for Writing Excellence.I can get live assistance,step by step guideââ¬â¢s and tutorials.I believe this will be a wonderful opportunity to learn different writing techniques and to make sure I am doing it all properly.The second resource I will utilize are the workshops.In my spare time,I will set a goal of at least 2 hours a week participating in a writing workshop to further my learning. What is your personal learning style (refer to the Ch. 1 Aplia homework)? I have learnedà that I am kinesthetic.I never knew there were so many different types of learning before I started this class.I always knew,even as a child,that if the subject didnââ¬â¢t appeal to me personally,I couldnââ¬â¢t pay attention or learn anything.Knowing the information I know now,I understand why I always had such a hard tim e with math. I learn by feeling something emotionally or seeing something be done. Seeing and feeling is the way I connect to everything.Numbers is one thing I donââ¬â¢t comprehend easily,but I succeed in reading because I can emotionally get involved in a story. What are two obstacles you might need to overcome (refer to your Life Factors and personality assessments)? Learning how to manage my time more efficiently.I need to figure out how to manage being a wife,mother,employee and student all in one day.Another obstacle is learning how to handle stress.When I feel overwhelmed,Itââ¬â¢s normally a very bad thing.I tend to freak out on everyone who means the most to me,which is something I need help with immediately.Itââ¬â¢s not fair to my family. Iââ¬â¢m going to be under alot of pressure juggling everything and I want to know how to properly deal with it. What strategies can you use to overcome these obstacles and be successful? I will get a calendar and start writing down my to-do l ist daily.I will set a time limit for each thing to manage my time correctly.As for my stress and anger,I will utilize the Life Resource Center. I am willing to take any advice given to me to help me become the best student,wife,mother and employee that I know I can be.I am willing and able to change,with the right guidance and techniques. How does knowing your personal learning style help you be successful? Knowing that I am kinesthetic and that I learn by seeing and feeling,makes me realize that I need to explore the other learning styles.Experimenting in other ways of learning,I may find that now that Iââ¬â¢m older and more experienced at life,ways I learned when I was younger,may not be the only way I can learn now. I honestly havenââ¬â¢t had to learn anything academically for so many years,that trying a new style,might not be such a bad idea. Do you feel you are ready for the academic and financial commitment of attending college? Yes.The reason I am ready,is because I have been procrastinating way too long.Life doesnââ¬â¢t wait for you to keep saying ââ¬Å"Iââ¬â¢ll do it next monthâ⬠¦next year,ect.â⬠Life goes on,whether youââ¬â¢re ready or not.Iââ¬â¢m 35 years old.My kids are growing up.

Iââ¬â¢m ready to put my all into this,and Iââ¬â¢m willing to work as hard as I can to pay for my expenses as well. How can goal setting and time management help you reach your goals? Goal setting and time management is extremely important,and also something I definitely need to improve. It will help me succeed in my dream of graduating and becoming a substance abuse counselor.Iââ¬â¢ve never been very good at setting goals properly in the past,or managing my time wisely.Now,after I have read the chapter on the subject,I have learned ways of becoming more efficient with my time. Having goals in life is something everyone needs. Goals give you hope,and something to look forward to.Learning to make the most of your time will help you achieve these goals and make you a more productive person.

Child Abuse Prevention Program Grant Proposal - 2736 Words
Abstract Child abuse is still a significant problem in United States. There are 2.9 million child abuse reports to Child Protective Services in 2005 and 825,000 indicated cases. Child abuse has profound impact on the childââ¬â¢s current and future development. The consequences include health and physical effects, intellectual and cognitive impact, and emotional, psychological and behavioral consequences. To improve parenting practice of first time parents is an important way to address this problem. The rate of child abuse is highest for children between birth and 3 years of age.

Cognitive behavioral category includes programs that combine behavioral strategies with cognitive strategies. Co gnitive strategies help parents to restructure their thinking about themselves and their children.

Humanistic category includes Webster-Stratton programs (Hughes, 2004) and programs with video ââ¬âtape modeling methods. We absorb elements from previous parenting training programs and form a Cognitive Behavioral Parent Training Program (CBPTP) for Child Abuse Prevention targeting first time mothers. Previous evaluation studies show that cognitive behavioral parenting programs are more effective than other kinds of parenting programs with respect to child abuse treatment and intervention (Barlow, 2006). Most of parenting programs specifically designed for child abuse problems are used as a tool for treatment of parents who have already exhibited maltreatment behavior and their children who have suffered maltreatment, for example, Abuse-Focused Cognitive Behavioral Therapy (AF-CBT). The most appropriate target population of AF-CBT is physically abusive parents and their school-aged children (Kolko, 1996).

Rotary Engine Essay Example
Rotary Engine Essay Svetlozar Simeonov 09/25/11 Wankel Rotary Engine ââ¬â Huge Power in a Small Box According to Philipââ¬â¢s Encyclopedia Wankel rotary engine or just Wankel engine is ââ¬Å"Internal combustion engine with rotors instead of pistons. â⬠That not so popular engine is actually about two times lighter than a four cylinder piston engine, the one that we all have in our cars, for the same power output. It also has four times less moving parts. Much simpler, much lighter, much smaller it has numerous advantages over a conventional piston engine. One of the most simple and clear explanation of how the Wankel engine works oppose to piston engine comes from Time magazine: ââ¬Å"Instead of converting up-and-down piston motion into wheel-driving circular energy through a series of complex linkagesââ¬âthe way a standard engine worksââ¬âthe Wankel rotors spin continuously and thus provide the proper torque to move a cars wheels directly. â⬠(Time Aug 14 1972). It has four times less moving parts versus four cylinder engine. Therefore, Wankel engines ââ¬Å"are smaller, peppier and potentially cheaper to build than conventional reciprocating models, and have only six major points of wear, v. 00 in a conventional engineâ⬠(Time Aug 14 1972). The Wankel engine was reviled in 1956 by its engineer Felix Wankel (The Columbia Encyclopedia ââ¬â internal-combustion engine). The first mass production car powered by Wankel engine was released in 1967 by the Japanese manufacture Mazda. It was a reference design, twin â⠬ârotor 982cc, outputting 110 hp. That made the 2000 pounds Cosmo model pretty zippy. Mazda quickly introduced 2 more models in 1970 and with prices significantly lower than its competition Mazdaââ¬â¢s success rapidly increased.

General Motors even had a Corvette on the way, when the 1973 oil crisis changed everything over. The Wankel engine at the time was less fuel efficient, so the sales suddenly dropped down so low that Mazda was a step away from bankrupt. They changed their strategy and rotary cars became a special line, instead of mainstream. Then and now, Mazda is the only manufacture to truly stand by this technology. It improved it radically in terms of output and fuel efficiency. Their last generation engine, called Renesis, used since 2003 in RX-8, has the same output like the previous generation 250hps, red line topping at 10 000 rpms. However, it is naturally aspirated, where the previous one was twin-turbo charged. The Renesis is also 25% more efficient. Sadly it wasnââ¬â¢t enough, and the RX-8 was discontinued in August 2011, with no successor announced. With the slow pace of its evolution, I hope we can see the next generation at the end of this decade. Mazda and the Wankel engine have won many awards and races. The most prestige one is the success in 1991 in the annual ââ¬Å"24 hours of Le Mansâ⬠, leaving behind drivers and teams with traditions like Mercedes, Jaguar and the frequent winner Porsche. The four-rotor engine outputting 700 hp lead the team first to the finish, regardless their start position ââ¬â 55. As William Welch states, in his recent publication in USA Today, ââ¬Å"the only Japanese car and only non-piston engined car to win the grueling French raceâ⬠(William M. Welch, USA Today 08/23/2011). ââ¬Å"Sanctioning bodies outlawed the engine after the win at Le Mansâ⬠and close the history of Wankel powered cars at this scramble (William M. Welch, USA Today 08/23/2011). That win however, confirmed the Wankel reputation of power and durability. Even though the Renesis was a big step forward, it was still a step behind the longer lived piston engine in terms of fuel economy. That was its only drawback, but enough to turn a lot of people away. Not so many had the chance to experience the fun side of this fast revving motor. Fossil fuels, like gasoline, are fated to become extremely rear and expensive and it looks like Mazda engineers are getting prepared for this scenario. In interview for Reuters news agency from 2007 Mazda executive Nobuhiro Hayama revealed their new strategy: ââ¬Å"Researchers at Japanese carmaker Mazda think cars will in future run on water component ââ¬â hydrogen. â⬠¦the advantage hydrogen fuel was that it could be used in internal combustion engines. However â⬠¦ there is a risk of abnormal combustion. This could be solved by using rotary enginesâ⬠(Tokyo Reuters Oct 22 2007). That means that a slightly modified RX-8 could reborn and satisfy the need of cheaper run and exciting pull, equipped with ââ¬Å"two fuel tanks, thoughâ⬠(Tokyo Reuters Oct 22 2007). We would expect the price to remain the same, since no direct modification to the engine is needed, and the car has paid of its investments already. It looks like a bright future for the Wankel. Removed paragraphs Taking in consideration the minimum moving parts of the Wankel engine, the aerocraft industry quickly realized its lifesaving advantage. In case of internal engine damage the engine would not fail right away. It will continue delivering power that will decrease with time. Its weight and size made it preferable for many small plane manufactures. It let the engineers improve aero dynamics of the plane nose, due to the smaller engine. The first complete Wankel engine was reviled in 1956 by its engineer Felix Wankel (The Columbia Encyclopedia ââ¬â internal-combustion engine). Since then, the engine received many improvements. The main contributor is the Japanese manufacture Mazda that started a line of sport cars with Wankel engines in mid-1960. The first model, named Cosmo, had a good success and two more models were released in 1970. Seeing the potential in this relatively new technology, a few more automobile manufactures build their own sport car prototypes including Mercedes-Benz and General Motors. The second had a prototype of the legendary Corvette. As every invention, this one also has disadvantage ââ¬â fuel efficiency. Hit by the first oil crisis in 1973, all manufactures except Mazda canceled their plans for a production Wankel powered car. Even more Mazda almost bankrupted, since they completely had abandoned reciprocating (piston) engines. Today Mazda is the only one to mass produce Wankel engine cars, and it has made huge, but slow progress in this field. The last generation named RX-8 had achieved better output with lower fuel consumption ââ¬â huge step forward from the previous RX-7.
