Pavlovs Dogs Essay Example

Pavlovs Dogs Essay Example Pavlovs Dogs Essay Pavlovs Dogs Essay Learning and Conditioning Ivan Pavlov examined hounds, metronomes, salivation, and the disclosure of the molded reflex almost 100 years back. Ivan will be recognized as the man who changed brain science by his experimentations with the salivation of pooches. Pavlov learned through experimentation of the unconditioned reactions because of unconditioned improvements and of the possibility to condition reactions from past no upgrades. Pavlov played out his investigations at the Institute of Experimental Medicine in Petrograd. There, he thought about his past work. He had seen during his past work that hounds normally created measures of salivation relying upon what they were given to eat. The mutts salivated little sums for damp food, bigger sums for dry food, and differing sums for unpalatable items. He at that point had the hypothesis that the mutts had gained as a matter of fact to connect food with the presence of specific signals-the molded upgrades. He set up a lab to prepare pooches to salivate aimlessly flags, molded improvements. Pavlov prevailing with regards to preparing pooches to slobber from hearing the hints of strides, ringers, metronomes and the smell of vanilla. He related the food, unconditioned improvements, with the already unbiased boosts and afterward rehashed the blend until the mutts would salivate at the aroma or sound without the need of the unconditioned upgrade. The most significant finding of the investigation was that if a nonpartisan boost was in contact with the pooches after the unconditioned reaction occurred, the impartial improvement would remain an unbiased reaction. The effect of Pavlov’s work showed us our conduct and the effect that molding has upon people. The hypothesis of old style molding is all around acknowledged and has stayed unaltered since its origination through Pavlov’s work. Different therapists have worked with Pavlov’s molding. John B. Watson, for instance, adapted 11-month-old little Albert to fear a white rodent (and other hairy things) by utilizing similar standards Pavlov used to condition salivation in hounds. Molding additionally straightforwardly identifies with the nature versus sustain contentions. Pavlov’s work shows that nature wherein we are encircled by has a section in our activities. All in all, it is far-fetched that such a durable, rich, and very much enunciated hypothesis of the molded reflex could ever have existed if Pavlov had not settled on the choice to hazard his profession and adventure into the untested, unfamiliar, and profoundly faulty study of nineteenth-century brain research.

Ethical Enviromental Issues Free Essays

string(126) outcomes of the dam venture, is it morally option to continue with the project? Actually, I don't think it is right. â€Å"Ethics is the investigation of the decisions individuals make with respect to right and wrong† (Ruggiero, 2008). Natural morals, it is all the more an examination about good connections of individuals to, and furthermore the worth and good status of, the earth and its nonhuman substance. People have been offering our lives to nature for a significant number of years; we need to settle on numerous moral choices as for the earth ordinary. We will compose a custom paper test on Moral Enviromental Issues or on the other hand any comparative theme just for you Request Now We have been focusing on discovering ways and thoughts to make our lives simpler. After some time we have neglected to take in the unethical thought of what we may be doing to our condition itself. Before, future and even present, there have been numerous disputable issues on natural morals that should be replied. There are natural issues influencing our present reality, for example, deforestation and contamination. These issues have even started to influence us at a worldwide scale and not just have we placed ourselves in grave hazard yet we have likewise figured out how to jeopardize each different species that exist on earth. As supported by Yamamoto (2001), â€Å"In Buddhism, human life, and different types of life are viewed as being of a similar issue. Consequently, since they are constantly identified with living things, Buddhism sees natural issues as basically an issue of morals. † There are numerous ecological issues that should be dealt with at the earliest opportunity. One issue would need to be deforestation. For a considerable length of time we as people have relied upon trees as an asset to our regular day to day existence. We have constructed homes, paper, and numerous different items from this valuable asset. In the event that the woodland furnished us with minimal effort homes thus numerous great assets, for what reason is it a moral issue or issue? This is an issue since deforestation pulverizes timberlands as well as diminishes the biodiversity, which implies a decrease in the sum, just as variety of, living things which can cause destruction on entire biological systems. † â€Å"The chopping down of tropical downpour backwoods is especially hindering to natural life and other living things. â€Å" (Yama moto, 2001) We have been so worry in finding various approaches to make our lives simpler. Contamination is another issue that is influencing our condition. Contamination is killing off our natural life each and regular. We as people must assume responsibility for this issue rapidly. With so much contamination we are slaughtering plants, creatures, dirtying our water, and causing the exhausting of the Ozone layer. I once needed to do a task about the impacts of The Morris J. Berman oils spill of the shore of the Escambron sea shore in the island of Puerto Rico. From the photos that I saw, I can say that I had never observed a progressively frightful sight. This excellent blue sea shore whose waters had transformed into a dim dark and loaded up with dead fish shrouded in oil. The harm was vey overpowering particularly. I will always remember the dreadful pictures of such a significant number of creatures choking with the toxic oil. Fortunately this issue has been managed by the administration for a long time and they have discovered numerous answers for guarantee that these debacles don't rehash themselves. This is an extraordinary case of how government includes itself in Environmental Ethics. It was apparent to each one the harm and the ghastliness that was dispensed on nature by this human setback. The legislature had consistently organized the rebuilding of the sea that was harmed by the freight boat when it smashed and obliterated the homes to countless maritime untamed life. A year ago the administration of Puerto Rico was remunerated with $10 million for harms brought about by the oil slick right around 14 years back. These assets will be utilized to fabricate a fake coral reef and a shore line nature hold (Michael Melia, FoxNews. com, 2007). Our downpour timberlands and the clans that live in there are being influenced by this contamination and deforestation too. â€Å"The Kayapo are an indigenous gathering of Indians living in the rainforest of Brazil. The predominant environments are tropical rainforest and meadow in which the Kayapo chase, fish, and practice Sweden farming (cut and consume). (Goodale, 2004) Their lifestyle is being undermined by contamination, land gets, and dams. There are numerous natural morals in question. The primary issue was the contamination from horticultural overflows from sections of land of soybean and dairy cattle simply beyond the Kayapo Indians. The contamination from the headwaters of the Xingu downriver streamed down to the Kayapo Indians, debasing water supplies and food assets. The subsequent issue was land intrusion. â€Å"Parts of the east bank of the Middle Xingu called Kapotnhinore are as a rule wrongfully attacked and sold. This is making an antagonistic, perilous condition and furthermore blocking waterway travel. (Goodale, 2004) The last issue influences the Kayapo Indian as well as influences the rainforest that they live in. As indicated by Goodale (2004), the Brazilian government has resuscitated designs for a few hydroelectric dams along the Xingu River. â€Å"The proposed venture would dislodge Kayapo from their homes, on the grounds that lost food for those living downstream, upset fish populaces, and harm earthly ecosystems† (Goodale, 2004). In a circumstance like this, there are numerous perspectives from the two sides. A few people accept this is simply unacceptable to upset a tribe’s common lifestyle. On the off chance that you take the waterway that they exclusively depend this will hurt their method of living. A few people believe that proposed arrangement ought to go ahead. Some accept that the dams will manage the progression of water which will help forestall flooding and dry seasons and that the production of the hydroelectric dams will make a perfect wellspring of power for millions. With a consistently developing populace, it doesn't bode well to have 28. 4 million sections of land put in a safe spot for just 5,000 individuals. When considering natural morals, there are numerous outcomes that people need to consider. Some are acceptable and some are terrible. Gauging the outcomes of the dam venture, is it morally option to continue with the undertaking? By and by, I don't think it is correct. You read Moral Enviromental Issues in classification Exposition models Although the dam can create power for some individuals, numerous others are being dislodged from their homes with no pay. I imagine that there are numerous different choices in making power without uprooting the Kayapo Indians. This isn't my choice to make. In the event that these issues are not managed in time, they could prompt serious results, for example, the elimination of numerous types of both greenery, and the frail states of various living spaces. Numerous individuals figure out how to go lighthearted through life; uninterested of the unsafe changes that are incurring upon our condition. It is basic that we go to the understanding that regardless of whether people are the predominant species on the planet; the earth doesn't exclusively have a place with us however to other living things. Despite the fact that a large number of our moral perspectives on Environmental issues are Anthropocentric as referenced by Andrew Brennan and Yeuk-Sze Lo (Environmental Ethics, January 3, 2008), we as the essential species have an obligation towards nature as well as have an ethical responsibility towards each different species that share our reality with us. We are the main species equipped for thinking and reflection on moral issues, along these lines giving all ethical discussion a positive â€Å"human-centeredness. † Personally I accept that maybe it is only up to us people to manage these issues right away. The endurance of every single other specie is basic; particularly when in all actuality we are the reasons for a considerable lot of the planet’s harms. A considerable lot of the social and moral commitments we have towards the planet comprise basically of broadening our ethical remaining past human centeredness. People must settle that we are only a small amount of living creatures in this tremendous world and we should think about our planet and the regard the other living animals that live on it moreover. Numerous individuals do truly feel that it is our ethical obligation to protect each part of excellence in nature by rewarding untamed life of all species with a â€Å"Big sibling complex. † I additionally accept that there are numerous human factors that are helping people to turn out to be progressively mindful of our obligations towards helping the earth. We live in a period of incredible social unrest and conflict between countries. Many perceive an approaching fate to our species circumscribing a not all that far off future. It is just consistent that numerous people are attempting to get back in contact with nature, as though searching for a feeling of guiltlessness that one looses as a kid. This is an honesty that was lost when man got imprudent with its capability to make and better his lifestyle. This mentality is getting blended and interwoven with the current developing cognizance that our reality is changing and it may be past the point where it is possible to take it back to the manner in which it was. It is significant that people start to make a move by drawing in moral conventions that worry our condition. In my ongoing exploration, I have discovered that the presence of strong Environmental Ethics is imperative for a move in a social mentality towards mindfulness regarding the matter maintain. These principles of direct and the qualities they mean must be kept up principally by the individuals, the legislature, and the parts of science that review worldwide and land issues. Educator Alasdair Cochrane of the London School of Economics and Political Science composes, â€Å"First of every single, natural ethic should be and will be educated by changes in the political endeavors to enhance ecological issues. Natural morals concerns detailing our ethical commitments with respect to the en

Negative Effects Of Modern Day Testing | Education

Negative Effects Of Modern Day Testing | Education Utilizing government sanctioned tests to assess understudies and educators has been an extraordinary error of the instructive framework. The apparently perfect thought that high grades demonstrate successful instructing and able understudies has neglected to be exact. As per Alfie Kohn in The Case Against Standardized Testing state administered tests cannot gauge activity, inventiveness, creative mind, calculated reasoning, interest, exertion, incongruity, judgment, duty, subtlety, positive attitude, moral reflection, or a large group of other important demeanors and traits. Understudies remember more than they learn and hold and don't become familiar with the equivalent and even instructors have been discovered cheating to keep their occupations. Numerous supporters even utilize government sanctioned tests to exploit the training framework. State sanctioned tests have subverted instruction and the achievement of numerous understudies. While most of present day people groups and inst ructors have acknowledged government sanctioned tests to be the best strategy for assessing understudies mental capacity, actually they neglect to epitomize the genuine capacity of individual understudies and educators while additionally affecting them contrarily. Government sanctioned tests appropriated by the state are known as high stakes tests. They are called so on the grounds that schools with high results can get acclaim and money related prizes while schools with low results are announced unacceptable and may get sanctions. Moreover, understudies with low scores might be kept down in a specific evaluation. These are a couple of the numerous stakes on the line with state sanctioned tests. It has just been as of late that schools have swapped utilization of state sanctioned tests for scholastic arrangement and for deciding understudy needs, with making a decision about understudies knowledge and keeping them away from certificates (Kohn). Impacts Against Students To most, this thought appears to be fine, however there are numerous issues with it. Gregory J. Shipper expresses that the National Association of School Psychologists thinks keeping understudies down is awful strategy with pulverizing impacts (3). Numerous urban communities have bombed understudies for underachieving in state sanctioned tests. In Baltimore, 20,000 understudies were kept down. For the understudy, being chosen as the imbecilic one could harm them mentally. Singular understudies could get left behind by the companions and companions they esteem most in their own evaluation level. Not exclusively will this impact people, yet enormous masses of understudies get kept down prompting tension about state administered tests. Understudies in same level evaluations may be at various degrees of their psychological turn of events, yet because of evaluation levels utilization old enough rather than insight level, a considerable lot of those understudies are stuck stepping through exams made for the high ground of the class and leaving them the outcomes of organic variables. . While it is a great idea to have understudies be at their own insight level with peers, it is smarter to change age level based evaluations. An expansion of disappointment and maintenance from grade level to review level could likewise prompt an expansion of dropout rates because of weight. In Boston, the dropout rate was expanded by 300 percent which was legitimately credited to state sanctioned tests (Merchant 3). It has likewise been inspected that tests made for instructive objects were one-sided on minority appreciation (Myers 334). As it were minorities by and large do more awful on these tests than a considerable lot of the predominant white dominant part. This additionally prompts huge numbers of those minorities, to feel inadmissible and in general more moronic. Being Hispanic in secondary school and watching a large number of my companions, kin, and family members who have dropped out, there have been numerous events in which Hispanics accept they couldn't further their training. My friends additionally had the outlook that they were to dropout or simply enter the workforce following secondary school. These stakes make understudies further dread tests as well as make them wonder, as they float through school, I this going to be on the test? Nervousness, dread, and outrage towards state administered tests are flooding understudies minds. Mentalities towards test not just show themselves in understudies through cheating and loafing yet additionally hinder accomplishment on tests by falling understudies with uneasiness. (Shipper 4). Ten million understudies in basic and optional schools performed underneath capacity on tests due to tension (Merchant 4). Shipper clarifies a potential increment because of the expanded accentuation and significance of testing (4). Tests have appeared to cause a ton of physical and mental issues for understudies. Truancy and stress all make the training framework contrarily sway understudies, particularly the youthful ones. The degree that cutting edge schools cause understudies to make progress toward greatness past the bustling work of the study hall is miserable. The most any understudy has to know is a condition and numbers to connect, however there is no real information on the real condition utilized. Presently, the only things that are in any way important is what will be on the test. What does mx + b mean when everything you do is plug in numbers as needs be. As far as I can tell with school I have never genuinely had to know and comprehend material completely to accomplish a passing mark despite the fact that I have strived to do as such. Besides I have just needed to think fundamentally in a bunch of circumstances. There has been A measurable relationship between high scores on government sanctioned tests and generally shallow reasoning (Kohn). Albeit numerous innovative scholars additionally score well on tests and many shallow masterminds once in a while score high, the bases that somebody c an excel on a test by just replicating down answers, speculating a great deal, and skirting the hard parts makes an extraordinary hole in precise estimations of understudies information (Kohn). Numerous understudies see little of the subject or strategies being utilized. While independently successful educators do help, it is still unbelievably hard to accomplish legitimate estimations in a contemporary day homeroom concentrating on state tests and different plans. Tests are presently utilized as a gauge for understudies and instructors accomplishment yet the scores don't appropriately mirror the nature of the scholarly community. Regardless, tests are a correlation of one individual comparative with the remainder of the number of inhabitants in understudies. This thusly makes it unfathomably hard to set up a test as per the information that ought to be set up at each level. One explanation behind that being that not every person at a similar age is at a similar level. Potential isn't estimated by where somebody is nevertheless where they can go. Another negative impact of this thought is that if a state with 140,000 understudies rose the standard cutoff score for a specific evaluation to be five additional percentiles, 7,000 understudies would not go to the following level or be viewed as normal (Merchant 2). Therefore, understudies likewise don't realize what they ought to realize or increase real insight. Gregory expresses that essential things that understudies should ace don't appear on tests, and because of cutoff points of time, a specific inquiries endeavoring to quantify information might be too not many to even consider having solid estimations of explicit expertise (Merchant 3). Gregory even proceeds to state that a couple of good theories or skipped answers may decide the ability level of understudies. State sanctioned tests at that point show their impediments in evaluating genuine understudy development (3). Consequences for Teachers For the eighteen years I have been in school endeavoring toward scholastic accomplishment and scoring huge numbers on state administered tests, the center has been subjective turn of events, understanding through idea. Despite the fact that this isn't awful, the manners in which schools have gone about it is horribly off-base. School, through my experience, has comprised of innumerable long periods of sitting in a room gazing toward what instructors were stating. This technique, while working for certain understudies, has neglected to genuinely challenge understudies intellectually just as not altogether educate others. One of the fundamental purposes behind these, to be perfectly honest, exhausting classes is state sanctioned tests. These capacities will eventually hurt the understudies. Do instructors attempt to show a balanced understudy or a decent test taker? Impacts of state sanctioned tests are effortlessly found in the study hall. It is likewise believed that great scores mirror the educators adequacy. Sitting tight time on planning for tests as opposed to learning other material is a genuine factor. Instructors stressed over awful tests scores invest a mind boggling measure of energy showing understudies how to step through examinations as opposed to showing learning aptitudes and information (Merchant 4). Educators start to concentrate on materials understudies need on the tests. The educational plan at that point begins to be limited. Gregory expresses that educators even quit concentrating on imaginative learning, for example, ventures, to reestablish address techniques (4). The awful piece of this is awful educators centered around tests could get made look like great instructors when in reality they are most certainly not. Schools cut out music, workmans hip, and social investigations to concentrate on perusing and math for tests and encourage them as needs be to excel on tests, which thus cuts a significant chance of learning for understudies. Indeed, even the ACT science test focusses on understudies capacity to peruse as opposed to information on science. These techniques don't simply hurt understudies by dismissing incalculable zones of study yet in addition by oppressing them as equivalent students. The hypothesis of Multiple Intelligence discloses to us that various individuals think and see in an unexpected way. Howard Gardner a notable clinician communicates insight in eight distinct bundles, one being in essence sensation which requires development not at all like that of a study hall. Another therapist, Robert Sternberg, proposed three insights. Sternberg called one of these insights scientific knowledge which communicates what might be known as knowledge designed for current school study hall (Myers 330 333). One of the perhaps most noticeably awful results of this recently discovered technique is the cheating by instructors all through the states. Since numerous states currently use tests to gauge educators as well, instructors start to cheat to keep their occupations just as show signs of improvement financing. While this thought isn't common there have be

My Philosophy of Teaching :: Philosophy of Education

Theory of Education Having moved on from a state funded educational system, I feel my encounters and sentiments are direct, yet they are something I ought to consistently attempt to consider when pondering or managing my own understudies. As each understudy has, I have had extraordinary instructors just as awful ones; a portion of those educators everybody adored or abhorred, and other got fluctuated suppositions about themselves from their understudies. The understudy instructor relationship is something that is unavoidable, as it ought to be. The explanation I am seeking after instructing as my calling is on the grounds that I comprehend that kids need somebody in their lives to have any kind of effect, and on the off chance that I could be that somebody for just my very own bunch understudies, I will have succeeded. I see instructing as being more than essentially telling a kid the best way to peruse as significant as that seems to be instructing is likewise about indicating a kid the significance of self. Without confidence, self-control and poise, there would not be numerous individuals who could make it effectively in today’s world. Furthermore, if I’m fruitful in showing youngsters how to peruse, just as something significant about themselves, I will have helped a few children get by as grown-ups. I don’t care anything about being the instructor that everybody believes is so cool and adores, nor would I like to be the one that everybody abhors. What I would like to be is an instructor that is regarded by my understudies since I have been reasonable and have allowed every one of them to pass and succeed. I need my understudies to confide in me. I need them to realize that I am not great and understand that none of them are, however I do trust that they understand that I do anticipate from them what I would anticipate from my self on the off chance that I were one of my own understudies. Information on subject is next on my rundown of significance. I realize how significant it is for my self to be proficient about the subject I am instructing; yet regardless of the amount I realize my understudies will just realize what I educate to them effectively.

How Strattera and Adderall Treat ADHD

How Strattera and Adderall Treat ADHD ADHD Treatment Print The Difference Between Strattera and Adderall By Jacqueline Sinfield facebook twitter Jacqueline Sinfield is an ADHD coach, and the author of Untapped Brilliance, How to Reach Your Full Potential As An Adult With ADHD. Learn about our editorial policy Jacqueline Sinfield Medically reviewed by a board-certified physician Updated on June 25, 2019 ADHD Overview Symptoms Causes Diagnosis Treatment Living With In Children istockphoto In This Article Table of Contents Expand How They Work Treatment Choices Forms, Dosages, and Efficacy Side Effects Risk of Abuse Black Box Warning View All Strattera and Adderall are medications prescribed to help treat attention-deficit/hyperactivity disorder (ADHD), a neurodevelopmental disorder characterized by difficulty with regulating attention and controlling impulses and hyperactivity. Both drugs improve attention span and decrease hyperactivity and impulsiveness; however, they are very different medications. The most striking difference between the two is that Strattera is a non-stimulant, while Adderall is a psychostimulant medication. How They Work These drugs are from different drug classes and work in distinct ways in the body. Strattera Strattera is a brand name for a drug that contains atomoxetine. It was approved by the U.S. Food and Drug Administration (FDA) in 2002 and became the first non-stimulant medication to receive approval for ADHD.?? It was also the first medication to be approved for treating adults with ADHD. It can be prescribed for people 6  years of age and older. Strattera is a norepinephrine reuptake inhibitor, which means it allows the neurotransmitter norepinephrine to be available to the brain’s neurons for longer. It also raises the quantity of the neurotransmitter dopamine in the prefrontal cortex of the brain. Adderall Adderall is a brand name for the combination of drugs dextroamphetamine and amphetamine. It belongs to the amphetamine drug family. The FDA approved this medication in 1996. In addition to ADHD, Adderall is also approved to treat narcolepsy. It can be prescribed to people ages 6 and up. Adderall acts on the central nervous system by boosting the number of neurotransmitters in the brain. This increase in dopamine and norepinephrine boost your ability to focus and pay attention while decreasing hyperactivity and impulsive behavior. Treatment Choices ADHD medication is divided into two categories: first-line medications and second-line medications. Stimulant medications like Adderall are known to be the most effective treatment for ADHD, and as such are considered first-line medication. Non-stimulant medications like Strattera are second-line medications. While not as effective as stimulants, they do still help ADHD symptoms. For example, studies found that Strattera reduced hyperactive, inattentive symptoms in adults compared to a placebo. However, 40% of the participants still reported significant ADHD symptoms. Although stimulants are the most effective medication, they dont work for everyone. In addition, sometimes people experience severe side effects with stimulants or have an underlying medical condition that increases the risks of taking a stimulant,  such as a history of addiction, a psychiatric condition like bipolar disorder, or a heart condition or  sleep disorder. In these cases, a non-stimulant medication like Strattera is an option. Strattera has also been found to sometimes  help with conditions that often co-exist with ADHD like anxiety and oppositional defiant behavior, a pattern of aggression, disobedience, and a lack of respect for authority. Forms, Dosages, and Efficacy Strattera is available in an oral capsule that comes in seven doses ranging from 10 to 100 milligrams (mg). Generic versions of the drug are available in the United States, Canada, and other countries. Adderall IR (immediate-release) is available in tablets from 5 mg to 30 mg. Adderall XR (extended-release) is available in six doses, from 5 mg to 30 mg. There are generic medications available (amphetamine salt combination), but sometimes  people report these arent as effective for them as the brand versions. It can take four to eight weeks before Strattera reaches its maximum therapeutic effect.?? Once therapeutic levels have been reached, the effects of the medication last 24 hours. In contrast, the effects of Adderall IR and Adderall XR can be felt as quickly as 30 minutes to one hour. The effects of Adderall IR begin to wear off after four hours, and after 12 hours for Adderall XR. Taking a break from the medication (a drug holiday) is an option with Adderall. After discussing it with your doctor, you might not take Adderall on the weekend or over holidays. Strattera needs to be taken every day.?? Side Effects For both medications, doctors usually prescribe a low dose, to begin with, and gradually increase it until the right therapeutic dose is found for you and your symptoms. This usually means youll have fewer side effects as your body adjusts to the medication. The side effects of Strattera include dry mouth, dizziness, upset stomach, and reduced appetite, constipation, reduced libido, and sweating. Men may experience some erectile dysfunction. The side effects of Adderall include loss of appetite, diarrhea, dizziness, dry mouth, fever, headache, insomnia, nausea, nervousness, sleep issues, vomiting, weight loss, and erectile dysfunction. More serious, but rare side effects are increased heart rate, high blood pressure, hallucinations, paranoia, shortness of breath, heart attack, and stroke. Cardiac Concerns Research has found that the likelihood of cardiac problems with the use of stimulant medications like Adderall is very low in healthy people.??  For example, one study found that people on stimulant medications for ADHD did not have an increased risk for cardiac events like heart attack, stroke, or sudden cardiac death. In the past, patients had electrocardiography (EKG) screenings if a stimulant medication was going to be prescribed. With new research findings, these screenings are no longer required unless you, or someone in your family, have a history of cardiac problems. If youre taking a stimulant and notice any unusual signs, contact your doctor immediately. ?? For Women Both medications are category-C drugs, which means theyre considered unsafe to take during pregnancy or while breastfeeding. Talk to your doctor if youre pregnant or planning to become pregnant. Risk of Abuse Adderall is a schedule-II controlled substance. This means theres the potential for abuse and that extended use might cause dependence. Because Adderall’s mode of action is to increase the activity of  the dopamine, it could be misused and inhaled or injected to create a high. Surges of dopamine cause the reinforcement of pleasurable but unhealthy behaviors like taking drugs, leading people to repeat the behavior again and again. That said, its reassuring to note that studies show that people taking a prescription stimulant have a lower rate of substance abuse compared to those not taking this type of medication. This could be because when ADHD is being treated safely, people are less likely to self-medicate and use non-prescription methods to manage their condition. When stimulant medications are prescribed at appropriate doses and taken as prescribed, the risk of potential addiction is low. Always store your medication safely away from other people, and dont share your medication. As a non-stimulant medication, Strattera is not a controlled substance and doesnt carry the potential risk for abuse. It works by inhibiting norepinephrine uptake, rather than significantly affecting dopamine. Because it takes several weeks for the medication to take effect, it would be difficult to abuse. Black Box Warning The FDA places a black-box warning on some prescription drug labels to bring attention to possible serious or life-threatening risks that people need to be aware of. Strattera has a black box warning for the possible increased risk of suicidal thoughts or actions in children, teens, and young adults. Parents and caregivers are encouraged to monitor possible changes in their child’s behavior and keep in close contact with the child’s doctor. Adderall has two black box warnings. The first is to highlight the potential for abuse. The second is to warn about cardiac events.

SAT Math Section Tips Triangles

Triangles can be very different! The SAT math section is full of triangles. They’re the most basic 2D shape that you can create and they can be found everywhere, so the SAT wants to make sure that you have the basic facts down pat. So let’s look at some tricks and facts about triangles. We’ll start by looking at the triangle below (not drawn to scale). 1) The angles of a triangle Fact 1: The angles of a triangle add up to 180 °. This fact you just have to drill into your head. It shows up time and time again on the SAT. It’s a specific case of the general rule that the angles of a shape with n sides add up to 180(n-2), but even if you forget that, keep the number 180 ° in your head. With that fact, we can then deduce that angle x is 72 °: 73 ° + 35 ° = 108 ° → 180 °- 108 ° = 72 ° 2) The third side of a triangle Fact 2: The third side of a triangle is greater than the difference of the other two sides and less than the sum of the other two sides. A question that might show up on the SAT is one that asks you for a possible length of the third side. Taking the fact above, we can find the lower and upper bounds: 14 - 5 = 9 14 + 5 = 19 Thus, side a must be between 9 and 19. 3) Angles and the side across from them Fact 3: The angles of a triangle are proportional to the sides across from them. What does this mean exactly? This means that the bigger an angle is, the bigger the side across from it is, and vice versa. So just eyeballing the triangle above, it might be hard to tell if side a or b is longer. But because we can see that angle y is clearly the largest angle, we can infer that a is the longest side. Angles x and z look fairly similar, but since side b is visibly longer than side c, we can infer that angle x is the smallest. Use facts like this to help you infer information about a triangle if the SAT question does not say â€Å"Not drawn to scale.† 4) The same angles Fact 4: If two triangles have the same angles, their sides are proportional to each other. 5) If two triangles are parallel Fact 5: If the sides of two triangles are all parallel, then their angles are equal. These two facts refer to what are called similar triangles. Similar triangles have the same angles and are thus proportional to each other. Observe the triangle (not drawn to scale) and the problem below: AF = 10, BE = 8, BD = 5, and CF = 15. AF and BE are parallel. What is the area of triangle BCE? First, let’s label the diagram. Because we need to find the area of triangle BCE and we know that the height is 5, we need to figure out the base (CE). So let’s label the diagram, calling CE x, since that is what we want to solve for in order to find the area of the smaller triangle: We use double lines to mark lines AF and BE as parallel. Fact 5 can be invoked here because if two lines overlap, they must be parallel. Thus, since CE and CF overlap and AC and BC overlap, they are also parallel. Therefore, triangles ACF and BCE share the same angles and are therefore similar triangles. Whenever you see any two triangles drawn overlapping like in the diagram above, you can immediately recognize them as similar triangles. So, let’s use Fact 4 now. You can either set up the proportion as: Big side 1 Small side 1 10 8 ------------- = ---------------- → ---- = ---- Big side 2 Small side 2 15 x OR: Big side 1 Big side 1 10 15 ---------------- = ----------------- → --- = ---- Small side 1 Small side 2 8 x Remember that the parallel sides must be either horizontal (as in the first case) or vertical (as in the second case) to each other. In the first equation, the bigger triangle’s side AF (10) is horizontal from the smaller triangle’s side BE (8). In the second equation, it is vertical from the smaller one. Both equations will yield 10x = 120 and therefore x = 12. We can then multiply this base 12 by the height 5 and divide by 2 (remember: a triangle’s area is  ½ * base * height (= bh/2) to yield the area of triangle BCE as 30. Remembering Special Right Triangles Beyond the basic equilateral, isosceles, and right triangles that you should remember, there are two key right triangles to memorize. These are the 45/45/90 triangle and the 30/60/90 triangle. Let’s look at the former first: Using fact 3 from above, we know that angles x and y must be the same, since the sides across from them are equal. Since they must add up to 90 °, each one must be 45 °: 90 ° + x + y = 180 ° x = y 90 ° + 2x = 180 ° 2x = 90 ° x = 45 ° y = 45 ° Now, what is side a? We can use the Pythagorean Theorem, remembering that a is the hypotenuse: 12 + 12 = a2 2 = a2 a = √2 45/45/90 triangles show up often on the SAT and it’s important to remember that they will always be in the following ratio because they all share the same angles (remember Fact 4 above): Now let’s take a look at a 30/60/90 triangle. These triangles lie in a 1, √3, 2 ratio. It’s relatively easy to remember the sides of these triangles: the trick is to count up from 1 and square root the highest number. For the 45/45/90 triangle, you know both equal sides have to be the smallest and so they are both 1. Count up to 2 for the hypotenuse and square root that. So a 45/45/90 triangle is in a 1:1:√2 ratio. For the 30/60/90 triangle, all three sides have to be different since angles are different. So counting up from 1 and square rooting the highest number will give you 1, 2, √3. But which side is which? Because √1 is 1 and √4 is 2, we know that √3 has to be the middle number, so it has to be across from 60 ° and 2 must be the hypotenuse as it is the largest number. The ratio then is 1:√3:2. Finding Triangles in Bigger Shapes Armed with these triangle tricks, we can solve what initially seem to be daunting problems. Take a look at the following problem (again, not drawn to scale): If the area of the semicircle from A to B is 13.5Ï€, CD is one third the length of AB, AB is parallel to CD, and angle CED is 60 °, then, what is the area of triangle CDE? So it seems at first that we have very little information, but let’s work on this systematically, going through each piece of information. Let’s use the first piece of information, that the semicircle’s area is 13.5Ï€. Notice that AB is the diameter of the semicircle. What would the area of the full circle be? Just double it and you get 27Ï€. From that area, we can work backwards to get the radius: Ï€r2 = 27Ï€ Divide by Ï€: r2 = 27 Square root both sides: r = √27 Factor it: r = √27 = √9 * √3 = 3√3 Now, the radius is half the diameter, so double it to get the diameter. 6√3 is the length ofline AB. CD is one third the length of AB, so it is 6√3 divided by 3 = 2√3. AB is parallel to CD and we see that AE and CE overlap and that BE and DE overlap. Therefore, the two triangles are similar and angle CDE must also be a right angle (like angle ABE). Angle CDE is 60 °, so we therefore have a 30/60/90 triangle! Let’s redraw the diagram with the information we’ve gathered. We have the height of triangle CDE (2√3) so now we just need to find the base (DE). Remember 30/60/90 triangles are in the ratio of 1:√3:2, so: 2√3 √3 ----- = ---- DE 1 Cross out √3 in the upper terms and you get that DE = 2. For good measure what is thelength of CE? It’s twice DE, so it must be 4. Now we can apply the triangle’s area formula (bh/2) 2 * 2√3 ----------- = 2√3 2 By now, you should be a master of triangles! When you see what looks like a complicated geometry problems, use these math SAT section tips and always look for triangles (and other familiar shapes like rectangles and circles) to use each piece of information step by step in order to get the information you need to solve the problem.
