This old saying holds true for ever and ever. Lies may get you out of trouble initially but in the end you will be in more trouble when the truth is found out. Therefore it is best to tell the truth at all times to save you from problems later. In addition, honesty helps a person to conquer problems and excel in life. It is essential for a person to be honest with himself. Only when a person plucks up the courage to face his inner values and emotion, can he get rid of the negative feelings which hold him back and as a result, find the confidence within. The confidence is what he needs in order to handle problems and perform well. Moreover, trust is produced by honesty. Without trust, a person has no credibility which is at the core of being able to influence others and provide strong leadership. These are very important qualities for a sisterhood and if my sister is someone I know I can trust and are loyal then they will always have a place in my life. However, you have to give to get. Therefore, if your sister is being good to you then you should also be good to them as well. Sisters are also there for your protection and emotional support as well. Being there when theres no one else to turn to and when theres no one there to save them. If your going through it and you feel like the world is out to get you then your sisters are the ones to turn to. If you feel threatened or scared they are the ones you go to. Sisterhood is a powerful thing that you grow from. It also improves your attitude as well. It betters you as a person and teaches you how to become a uccessful young independent woman. I can relate to sisterhood because Im the oldest of my two youngest sisters at home, Kamiyah and Mikaya. They look up to me not Just as a big sister but as a role model. Im there for them through everything as they grow up, for advice and to Just have someone to sleep with at night when they dont want to be alone. My sisters know that they can always come to me even if its to play and have a good time together. I teach them whats right and whats wrong and how to be a respectable young lady. I will always cherish the bond I have with my younger sisters and some day I hope they will choose to be apart of the Bennett sisterhood as well. Sisters are forever and a bond that can never be broken. With all the qualities that I have mentioned you would always want your sister by your side. Whether you are sisters by blood or Just from a close friendship, once a sister always a sister. Theres nothing like having that close relationship with someone so I hope that every female gets the chance of being in a sisterhood one day.

Psychology for creativity Essay Example

Psychology for creativity Essay 1. Creativity is a function of inborn characteristics and aptitude, influenced by upbringing, family and social environment. I believe that this statement is important in terms of developing and having access to ones own personal creativity. According to Csikszentmihaly there is a genetic disposition to our creativity and having access to his creativity when needed. There are ten dimensions that determine who and what makes a real creative person. Some of these characteristics are (1) physical energy-creative people have a great deal of physical energy but at the same time are peaceful. (2) Creative people are smart yet contain innocence at the same time. (3) Creative people contain a combination of discipline and playfulness at the same time. (4) Go back and forth between imagination/fantasy to being rooted/realistic. (5) Contain both extrovert and introverted qualities. (6) Are humble yet proud, (7) have a combination of masculine and feminine qualities, (8) have a combination of r ebel and conformist characteristics. (9) They are very passionate when it comes to work, yet they are objective about the situation. (10) Creative people are sensitive, therefore they are prone to suffer, but at the same time has a lot of enjoyment. Creative people are the ones who can act on both sides of the spectrum; they can run on both ends of these polarities. I believe that the ten dimensions are things that I do recognize within my personal creativity, in many ways I find myself having many of these spectrums. And I find it very interesting that the creative person is neither one nor the other, but both. Sometimes a person questions whether its right to be at both ends of the spectrum, but after reading this I found out that it is quite normal and promotes creativity. There are also factors during ones own developmental phase that can bring about the creative person within such as being firstborn, surviving a big loss of one or both parents when young, having a diversified environment, exposure to wide range of Ideas, being a book lover, lots of hobbies, good working habits, and interestingly enough the creative person is someone in conflict. I am actually the first born; I have three younger half siblings, and therefore technically considered an only child as well. When I was six years old I suffered some serious trauma when both of my grandparents died a month a part from each other. I was very close to them and considered them to be like my parents, so close that our apartments were on the same floor of our apartment building. Shortly after my parents got divorced, and what I considered a perfect world fell apart in a matter of weeks.

I think in many ways it almost made special and I knew from that day forth that I was a lot different than many of my peers. From that point on life was not easy, it was like a tumbling wheel, everything that could possibly go wrong did. However at the same time I did see that the melancholy of my life allowed me to access a creative side as well. I always felt musically inclined, I love to sing, dance, play guitar, act, etc Interestingly enough I took the arts very seriously and considered myself creative and considered myself one of the best. According to Amabile, family lives of young people help develop the creative self. Parenting style and home atmosphere apparently has more of an impact on determining creativity than genetics, therefore home life is a very important role in raising a creative person. Parents who have less rules have more creative children. Families with creative teens have unconventional furnishings. Creative children suffer more traumas. Growing up I felt a lot more unconventional than the rest, my parents were in some way considered hippies and I was allowed to do pretty much whatever I wanted. I never was grounded or had any rules, which isnt always such a great thing; however I was free to find myself. I can see that rules may somehow cut a person free will and creativity to flow. 2. Creativity is largely a function of the unconscious mind-its particular voice and content-as mediated by the conscious mind. We can access our unconscious content so as to heighten our creativity. What is creativity? What goes on during this process? Psychoanalysis gives us certain explanations on how this process is possible, and also on its benefits for both its author and public. Freud admitted to not being able to fully, in my opinion- account for the artists gift using the psychoanalytic method. The creative process is, according to Freud, an alternative to neurosis, that is a defense mechanism protecting against neurosis, leading thus to the production of a socially acceptable source of entertainment and pleasure for the public. For the artist has the ability of turning his fantasies into artistic creations instead of into symptoms. The unconscious plays a major role in the act of creation. That is, the act of creation is made possible by the libido, the energy of the id, and by a defense mechanism considered to be the most beneficial sublimation. By turning the sexual desire into a cultural manifestation with the help of the ego, sublimation makes the thoughts of the unconscious more acceptable to the conscious and it also allows for something productive, and pleasant, for the others as well. Art makes use of defense mechanisms such as condensation and displacement terms also used for work on the dream process, due to the role of the unconscious in both creative and dream processes. Art itself can be regarded as a defense mechanism. The artistic creation may be, for the artist, wish fulfillment or fantasy gratification of desires denied by the reality principle or prohibited by moral codes. Art is thus a means of giving expression to, and dealing with, various psychic pressures. The artist can work his fantasy a substitute for satisfaction by means of sublimation, into a socially acceptable form, art, that the others can enjoy. He works out the personal in his daydreams, fantasies into something he can share with the public. Some believe that creativity is intertwined with repression and pain. Freud did claim that the artists use their work to project in the outside world unfulfilled fantasies. However, in his view, a good poem is sublimation, and not a repression. Moreover, there is this ability of the artist to create and not become ill with phobia. I believe that many of times growing up I chose to do many things such that involved the arts so that deal with things in my life that were not the easiest to deal with. Any artistic creation is a compromise between the unconscious and conscious intent of its author. According to Freud, the artist can choose and make changes in the unconscious material. This and the way the artist transforms his egotistic fantasies into something acceptable for public appreciation could be regarded as parts of the artists gift. The fantasies of a man of artistic talent give us pleasure, while those of an ordinary day-dreamer could leave us indifferent, or bore or disgust us; or, while we might find that the fantasies of an ordinary day-dreamer have something in common to ours, his work would not have the same value as a true, gifted artists, and the day-dreamer will not be interested in sharing his work and reworking it for the public 3. The creative mind is an eccentric one and can be close in processing style to the pathological mind. Creativity could be described as the ability to create products or ideas which are original and which possess a strong social usefulness. To create, indeed, implies the production of something new and original. However the qualities that make an individual able to produce new entities are not well understood. As is also the case with the concept known as intelligence, it is unlikely there is a general creativity factor unevenly distributed across the population. Rather, creativity can be conceived as a complex of qualities that allow some people more easily than others to produce new objects or ideas. Most studies show that there is a link between creative ability and the risk of mental disorder: in fact, the prevalence of mental problems among creatively gifted people is often, but not always, significantly higher than among the general population. Studies on the relationship between creativity and mental illnesses suggest that they are the same characteristics of the disorder, in their less severe manifestations, which confer some advantage on afflicted individuals and their relatives. 4 .The creative processes has a life of its own, I believe it can be greatly influenced by practices and conscious actions. There are many practices that can help influence the creative process such as visualization processes, having a higher responsibility, repeating questions to uncover your blocks (perfectionism, fear, shame)owning your shadow- using Jungian theory to help find certain archetypes of your life. Always having a witness consciousness to whatever you may be doing. All these exercises can help with coming closer to the creative process; it allows you to have access to your creativity and keep the energy flowing where it may sometimes be stagnant. I think these exercises are important to help not only to get your creative juices flowing, but it also allows you to really take control of your life and the obstacles that you may encounter along the way. Exercises such as owning your shadow really give you a sense on how important it is for you to be real with yourself. Because if you are not honest with yourself, I doubt you will ever get to the core of what really in life moves you or makes you tick. It is okay to have feelings that may not be so called appropriate in that exact moment, but just as long as you own yourself and you true feelings, you can see that it is okay to pass through these times of darkness, and that it is acceptable to not be smiling all the time. Everyone has a dark side and there is nothing wrong with that, it simply is just how life is. Having a higher responsibility also helps the person become more aware of their surroundings, and not just think about themselves. Personally when after doing this higher responsibility I realized that its such a rewarding feeling that you feel when you give freely to someone without necessarily getting something in return. I believe that a lot of people are selfish and usually give because they know they will be getting something in return. I think that when you finally decide to give without thinking of what you will receive it is a lot more rewarding. The list of five was also another great exercise to get those creativity juices flowing; it gives you an opportunity to really dig in and see what really makes you tick, what goals you may soon want to achieve, what hold you back in life, and all together allows you to become more aware of all the things that may be possible in achieving within this lifetime. Another wonderful exercise that I found unbelievably interesting was the visualization exercise, I thought that it was a great way in learning how to take more control of your life and the things that you may want to create within your life. A lot of the times people are lost and do not see the light at the end of the tunnel, it is hard because people will lose themselves the chaos of life, lets say for example you are dealing with an illness, it may very well be hard to overcome that, however doing visualization exercises particularly helps in problems such as these. It trains your brain to start creating these solutions, by first just thinking about it; imagining it and then eventually making it a reality. Creative process does have a life of its own, these exercises allow you to take charge of your life and move into a whole new realm of creativity. It brings you closer to the things in your life that you may have not been able to achieve because you couldnt see how to really achieve these things before and make it a reality. 5. What do you think is the source of creativity? The creative spirit? From where does the motivation for creativity come? Creativity is the quality that you bring to the activity that you are doing. It is an attitude, an inner approach how you look at things. Really, the experience of creativity is an entry into the mysterious. Technique, expertise and knowledge are just tools; the key is to abandon oneself to the energy that fuels the birth of all things. This energy has no form or structure, yet all the forms and structures come out of it. It makes no difference what particular form your creativity takes it can be painting or singing, planting a garden or making a meal. The important thing is to be open to what wants to be expressed through you. I believe that we dont possess our creations; they do not belong to us. True creativity arises from a union with the divine, with the mystical and the unknowable. Then it is both a joy for the creator and a blessing to others. 6. How does creative thinking differ from ordinary thinking? Creative thinking is different from ordinary thinking because it gets to you to start focusing on this different type of energy. Some examples of some skills associated with creativity are Breaking out of old patterns and doing something different, keeping options open, not judging so quickly, thinking broadly- trying to see relationships between different ideas, breaking through ordinary way of doing things, trying to perceive things in a new and exciting way, using exercises to help get those creative juices flowing more freely. Basically creativity thinking is more innovative and free, being able to try new ideas and things to encourage more creative progress. Learning to become more open to new ways of promoting these different ways of doing things, creativity is daring to be different; making the difference. According to Osborne things that promote creativity are traveling, playing games, solving puzzles, pursuing hobbies, and reading/writing Ordinary thinking is stagnant; it does not have a unique sense. It wears the same old boring t-shirt and jeans every day. Ordinary thinking simply follows the crowd and never tries to be the one to stand away from the crowd and try something new. According t Osborne factors that cramp creativity are sticking to previous habits, self-discouragement, timidity, and urbanization. A statement I always love to say in honor of creativity is: Dare to be different and the rest will follow! 7. Do you think the genius is born or made? Weisberg posits that the primary factors in genius or extraordinary accomplishments are skill, motivation and discipline. According to Weisberg genius are in born, that it is a natural ability that we are born with. Personally I would have to agree and say that it is something innate and something that we can all attain. Also in terms of creativity everyones has the ability to access it as much as they want. He also states that this idea of geniuses is a view that is very rooted in the past. He believes that the idea of a genius is more of a myth, therefore it does not exist, meaning that we all have this capability to be so called geniuses. He states that creativity is within everyone and that we all have ability to attain these achievements just as long as improve skill, are motivated and disciplined enough to achieve these goals and ideas. Weisberg also points out that in theory we all have the same cognitive abilities as a so called genius, so what makes them so different? Apparently nothing, we have the same capability to weave and create different Ideas / inventions that have not yet been thought of as much a genius could or even more than genius would. Creativity is in access to all that is new, different, exciting, innovative, loving, peaceful, fun, and the opposite of all that we do on a daily basis. Creativity is about living to your potential and shaking up the earth. We all are to accomplish these set out aspirations for ourselves just as long as we believe and really yearn to do so, nothing in the world should/could stop you.

Comparison of Assassins essays

Comparison of Assassins essays Assassins generally are categorized as people whom kill or attempt to kill prominent figures in their time. Everyone else involved in the attempt of or succeeding in executing another individual might be described as a killer, murderer, and so on. This paper will describe any similarities or differences in the below listed individuals considered as assassins: Of the individuals mentioned above, all of these men either attempted to or actually managed to assassinate a political figure in our history. Some of these figures were better known than others, but were well known by American society at the time. A brief description on the background of each of these men will provide the base level data for our analysis. Each of them will also be characterized due to their prior history and background using models provided by those who psychoanalyzed assassins and their profiles. John Wilkes Booth was born in a log cabin near Bel Air, Maryland on May 10, 1838. The son of Junius Brutus Booth and Mary Ann Holmes had stood in the shadow of his father, the renowned actor, and his older brother, Edwin. The Booth family in general was known for alcoholism and bouts of depression.  ¡Wilkes ¡, as people would call him, was a great supporter of the South when the civil war broke out. His brother was a staunch supporter of Lincoln. Wilkes had chosen to stay in the north, which struck most people that knew him as  ¡odd ¡.

AP Chemistry Syllabus What Does It Cover

AP Chemistry Syllabus What Does It Cover SAT / ACT Prep Online Guides and Tips What does an AP Chemistry syllabus look like? How many labs do you have to do? And what skills are you expected to learn before the test? In this article, I'll take an in-depth look at the components of a successful AP Chemistry syllabus, including content coverage, lab work, and overall curriculum requirements. I'll also give an example of a full syllabus (based on a sample from the College Board) and provide some helpful tips for both students and teachers! What Does the AP Chemistry Course Cover? AP Chemistry is a wide-ranging course. The curriculum is divided into six "Big Ideas," or major themes, that encompass long lists of smaller topics. I'll list the Big Ideas along with the smaller themes within them that the College Board calls "Enduring Understandings." These are actually broken down further into pieces of "Essential Knowledge," which (for the sake of keeping this article to a reasonable length) are not included here. There are also seven Scientific Practices that students are expected to master in the course, which I'll list after the Big Ideas. This is a part of the new inquiry-based model of AP science courses that encourages independent thinking. Finally, there are some overarching Curricular Requirements that every AP Chemistry class must fulfill, which I'll go over after the Scientific Practices. For the full course description with even more details, consult this link! The 6 Big Ideas of AP Chemistry The Big Ideas are the fundamental concepts every AP Chemistry syllabus must cover. Big Idea 1: The chemical elements are fundamental building materials of matter, and all matter can be understood in terms of arrangement of atoms. These atoms retain their identities in chemical reactions. Enduring Understanding 1.A: All matter is made of atoms. There are a limited number of types of atoms; these are the elements. EU 1.B: The atoms of each element have unique structures arising from interactions between electrons and nuclei. EU 1.C: Elements display periodicity in their properties when the elements are organized according to increasing atomic number. Periodicity is a useful principle for understanding properties and predicting trends in properties. EU 1.D: Atoms are so small that they are difficult to study directly; atomic models are constructed to explain experimental data on collections of atoms. EU 1.E: Atoms are conserved in physical and chemical processes. Big Idea 2: Chemical and physical properties of materials can be explained by the structure and arrangement of atoms, ions, or molecules and the forces between them. EU 2.A: Matter can be described by its physical properties. The physical properties of a substance generally depend on the spacing between the particles (atoms, molecules, ions) that make up the substance and the forces of attraction among them. EU 2.B: Forces of attraction between particles (including the noble gases and also different parts of some large molecules) are important in determining many macroscopic properties of a substance, including how the observable physical state changes with temperature. EU 2.C: The strong electrostatic forces of attraction holding atoms together in a unit are called chemical bonds. EU 2.D: The type of bonding in the solid state can be deduced from the properties of the solid state. Big Idea 3: Changes in matter involve the rearrangement and/or reorganization of atoms and/or the transfer of electrons. EU 3.A: Chemical changes are represented by a balanced chemical equation that identifies the ratios with which reactants react and products form. EU 3.B: Chemical reactions can be classified by considering what the reactants are, what the products are, or how they change from one into the other. Classes of chemical reactions include synthesis, decomposition, acid-base, and oxidation-reduction reactions. EU 3.C: Chemical and physical transformations may be observed in several ways and typically involve a change in energy. Big Idea 4: Rates of chemical reactions are determined by details of the molecular collisions. EU 4.A: Reaction rates that depend on temperature and other environmental factors are determined by measuring changes in concentrations of reactants or products over time. EU 4.B: Elementary reactions are mediated by collisions between molecules. Only collisions having sufficient energy and proper relative orientation of reactants lead to products. EU 4.C: Many reactions proceed via a series of elementary reactions. EU 4.D: Reaction rates may be increased by the presence of a catalyst. Big Idea 5: The laws of thermodynamics describe the essential role of energy and explain and predict the direction of changes in matter. EU 5.A: Two systems with different temperatures that are in thermal contact will exchange energy. The quantity of thermal energy transferred from one system to another. EU 5.B: Energy is neither created nor destroyed, but only transformed from one form to another. EU 5.C: Breaking bonds requires energy, and making bonds releases energy. EU 5.D: Electrostatic forces exist between molecules as well as between atoms or ions, and breaking the resultant intermolecular attractions requires energy. EU 5.E: Chemical or physical processes are driven by a decrease in enthalpy or an increase in entropy, or both. Big Idea 6: Any bond or intermolecular attraction that can be formed can be broken. These two processes are in a dynamic competition, sensitive to initial conditions and external perturbations. EU 6.A: Chemical equilibrium is a dynamic, reversible state in which rates of opposing processes are equal. EU 6.B: Systems at equilibrium are responsive to external perturbations, with the response leading to a change in the composition of the system. EU 6.C: Chemical equilibrium plays an important role in acid-base chemistry and in solubility. EU 6.D: The equilibrium constant is related to temperature and the difference in Gibbs free energy between reactants and products. This idea is huge by itself, and now you're telling me there are five more Sigh. Another day another dollar. The 7 Scientific Practices of AP Chemistry These seven "scientific practices" represent skills that students are expected to learn in AP Chemistry. Many of these relate to correct implementation of the scientific method in a lab context. They're especially tied to the "Guided Inquiry" labs, where students work independently to plan and conduct experiments. #1: The student can use representations and models to communicate scientific phenomena and solve scientific problems. #2: The student can use mathematics appropriately. #3: The student can engage in scientific questioning to extend thinking or to guide investigations within the context of the AP course. #4: The student can plan and implement data collection strategies in relation to a particular scientific question. [Note: Data can be collected from many different sources, e.g., investigations, scientific observations, the findings of others, historic reconstruction, and/or archived data.] #5: The student can perform data analysis and evaluation of evidence. #6: The student can work with scientific explanations and theories. #7: The student is able to connect and relate knowledge across various scales, concepts, and representations in and across domains. AP Chemistry Curricular Requirements The curricular requirements are concrete statements of expectations for the AP Chemistry course. These include requirements for the types of materials teachers must use in class, the structural framework of the course, the opportunities students should receive, and the percentage of class time devoted to labs. The course must use a recently published (within the past ten years) college-level chemistry textbook. The course must be structured around the Enduring Understandings within the Big Ideas as described in the AP Chemistry curriculum framework. Students should have opportunities outside of laboratory investigations to meet the learning objectives within each of the big ideas in the AP Chemistry curriculum. Students have the opportunity to connect their knowledge of chemistry and science to major societal or technological components to help them become scientifically literate citizens. Labs make up 25 percent of the instructional time at minimum and include at least 16 hands-on experiments. Lab investigations allow students to apply the seven science practices, and at least 6 of the 16 labs are conducted in a guided-inquiry format. "Guided inquiry" labs put students at the center of the learning process, encouraging them to pose, develop, and experimentally investigate questions (self-generated or supplied). Other more traditional labs are teacher-directed, which means that teachers provide not only the questions for investigation, but also set procedures and data collection strategies for student use. The course provides opportunities for students to develop, record, and maintain evidence of their verbal, written, and graphic communication skills through lab reports, summaries of literature or scientific investigations, and oral, written, and graphic presentations. Keep in mind that it takes a while for most students to learn how to hold presentation materials in ways that don't completely obscure their faces. Work on it. You'll get there, buddy. What Does an AP Chemistry Syllabus Look Like? The following is a summary of a sample syllabus supplied by the College Board that goes through all the units that would be taught in a standard AP Chemistry course. It also provides the number of class periods allotted for each unit. In this example, the class periods are 52 minutes long.

Teaching Tips for AP Chemistry These are some tips I came up with for AP Chemistry teachers based on my experiences as a student in the course. I struggled a lot with chemistry in high school (partially because my teacher wasn't very good), so here are a few things that I think would have helped me out at the time. Tip #1: Do Plenty of Sample Problems in Class (and Go Over Homework Thoroughly) When I was in AP Chemistry, I had a hard time understanding how to solve complex multi-step problems. I often couldn't figure them out on my own, even when I had read examples in the textbook and seen my teacher go through similar examples. I'd advise teachers to do as many sample problems as possible in class. It's important to give students background information, but walking through sample problems step-by-step is the most valuable practical instruction you can provide. You should also go through homework problem sets in class so that students can see exactly where they made mistakes and why. Encourage students to try redoing the problems with the new information they've learned to reinforce the correct methods. Tip #2: Offer Extra Help Sessions Because AP Chemistry is such a challenging class, it's likely that many students will be interested in extra help outside of the designated class period. Although students should be encouraged to take the initiative in asking for help, I think it's also a good idea to set up a designated time when you'll be available after school. Block out a couple of after-school hours one or two days a week, and encourage students to come to you with any questions or concerns they have about the class. You can also set aside times for review sessions before each exam that all students are encouraged to attend. These could even include chemistry-themed review games and competitions (if your students are true nerds they will love this). Tip #3: Give Students Real AP Practice Tests To prepare effectively for the AP test, students need to get used to the format and timing. As you get closer to the exam, administer a few mock AP tests. Translate grades to where they would fall on the AP scale so that students have a better idea of where they're scoring and how much they need to study to reach their goals. This will help give them more motivation to study and force any stragglers to get serious about improving their scores. Grades on real AP practice tests will help light a fire under students who have a tendency to procrastinate and cram. Tips for AP Chemistry Students If, on the other hand you're an AP Chemistry student, you may find these tips for doing well in this challenging class helpful. Tip #1: Pay Attention in Class Obviously, right? Well, not necessarily; zoning out during lectures is something that we're all guilty of doing because we're human beings. However, this is a class where you really, really need to pay attention to your teacher's explanations. It's hard to self-teach chemistry because you're not just memorizing facts, you're learning how to do different types of calculations and navigate a bunch of new terminologies. If you can only pay attention to one thing, make it the example problems that your teacher does in class. Take notes on the solution steps so you can refer to them in the future and refresh your memory. Tip #2: Ask Lots of Questions (and Get Help If You Need It!) If you don't understand something, get clarification as soon as possible. AP Chemistry isn't a class where you can let a few things fall by the wayside and still get by. The information builds on itself, so it's critical that you have a strong understanding of every concept. Gaps in knowledge will come back to bite you in the end! If you don't feel like you're getting enough of an explanation in class, don't be afraid to ask your teacher for extra help. Tip #3: Don't Fall Behind It will be tempting to say "oh, I don't actually need to do this problem set" or "eh, I'll read this chapter later." But if you do that too many times, before you know it you'll have no idea what's happening in class. This course moves very quickly from one complex concept to the next, so you can't afford to fall behind. As I mentioned, concepts build on one another. If you find yourself slipping and losing touch with what's going on in the course, ask your teacher for extra help as soon as possible to resolve the issue. Tip #4: Get a Review Book, and Review Concepts Throughout the Year Review books can be very helpful for AP Chemistry because they're well-organized catalogs of all the different concepts you will learn in the course. There's so much packed into the curriculum that I'd recommend buying a book so you have something to ground yourself as you're looking back through the material. You can use the review book for practice problems and AP review sessions throughout the year. Every couple of months, do a review of everything you've learned so far to keep the information at the front of your mind. Here's my list of the best review books for AP Chemistry to give you a lil head start. Review books will lay out the structure of the course more clearly for you so that you don't get lost in your notes! Conclusion To recap, the AP Chemistry syllabus revolves around six "Big Ideas," which are main themes that cover more specific concepts called "Enduring Understandings." Each AP Chemistry course is expected to give students the skills they need to understand these larger themes and connect them to a basic factual knowledge of the ins and outs of chemistry. Additionally, an effective course syllabus provides assignments that enable students to master the seven "Scientific Practices" established by the course guidelines. It will also adhere to the rules established by the Curriculum Requirements. A few tips I would recommend for teaching this course are: #1: Do Lots of Sample Problems in Class#2: Offer Built-In Extra Help Sessions#3: Administer Official Practice AP Tests Some tips I would recommend for students who want to do well in AP Chemistry are: #1: Pay Attention in Class#2: Ask Questions, and Get Help if You Need It#3: Avoid Slacking Off and Falling Behind#4: Use a Review Book to Supplement Class Materials AP Chemistry is a fast-paced class that covers complex concepts, but with a logically formatted syllabus and a concerted effort from both students and teachers, the course can be an enlightening introduction to a fundamental aspect of how the world works!

MAR Income Statement Research Paper Example | Topics and Well Written Essays - 750 words - 1

MAR Income Statement - Research Paper Example However, there has been a lot of stiff competition within the international organizations that deal with hospitality operations but the Marriott International Incorporation has maintained standards of being among the few that maintain a competitive advantage (Hartman & Werhane, 2009). The core principle that facilitates the great returns or rather success to the Marriott International Incorporation is the element of effective top management. This majorly consists of the board of directors that are having sufficient knowledge in the line of hospitality management and supervision. Due to this focus and teamwork, the organization still looks forward to a great establishment thus economic growth and development. The board of directors, including the general manager or chief executive officer, has very defined roles and responsibilities within a business organization. Fundamentally, it is the role of the board of directors to hire the general manager of the business and evaluate the overall direction and strategy of the business (Finance.yahoo.com). The general manager is responsible for hiring all of the other employees and overseeing the day-to-day operation of the business. On the contrary, management is not responsible for the overall policy decisions of the business. Some of the major responsibilities of the board of directors include: The process of evaluating, recruiting, supervising, retaining, and compensating the general manager is probably the most important functions of the board of directors. Value-added business boards need to aggressively search for the best possible candidate for this position (Hartman & Werhane, 2014). Actively searching within your industry can lead to the identification of very capable people Directing the Marriot International Incorporation effectively as the board has a strategic function in providing the vision, mission, and goals of the organization. These are often determined in combination with the chief executive officer of the business.

The detection of liver (hepatic carcinoma) image protocol using Research Proposal

The detection of liver (hepatic carcinoma) image protocol using 64-MDCT. The effect of contrast injection technique, patient size and low dose parameters on the image quality - Research Proposal Example The use of CT in detection of the liver has been there for several years. Parameters that control radiation calculation are many. For example, the default solutions, and iteration parameters, are used in most problems. The process of detection using the 64-MDCT requires patients that have lesions that are surgically proven. These patients then will have to undergo through the triple phase 64-MDCT process. The patients will be observed independently. Later, a thorough evaluation of MR and CT imaging process is required. This is done on a lesion-by-lesion point. According to Hayat (2009), the reproductively, negative and positive values and sensitivity are then evaluated. The diagnostic accuracy of the method is assessed against the alternative free response characteristics analysis. The main objective of the project is to develop a simple methodology. This is where users can establish exposure factors that can be practical to patients. This includes the patients with different body weights. The method is used instead of, relying on the current approach of using default values based upon standard sized patient. They developed a simple mAs prediction equation to optimize radiation dose for all patient weight categories. The results showed that patient weight can be a good predictor of required dose. In addition, an agreement can be reached, at a certain noise level, to be acceptable. Moreover, the value could be increased for larger patients. The radiation dose reduction requires the lowering of kV or mA settings, Schoenberg (2007). This will, however, increase the noise when all other settings are kept constant. The mA settings are adjusted continuously until the best results are achieved. The reduction of tube voltage is done. This is a strategy of reducing the dose as the image quality is improved. The attenuation of calcium and iodine levels is increased at lower kV.
