The water tanks had an increase in Compounds that form H+ ions in the water ankhs (acids; pH of three and five) and an increase Compounds that form OH ions (basis; pH of twelve) as our classed has learned about this in the biochemistry unit. The reason why people would care about our data results and experiment is t hat the Daphnia and the the different pHs are just a representation of what can happen in the real world as aquatic habitats and ecosystems can be critically impacted as different forms Of acids, such as acidic rain and bases and can kill not just Daphnia but also other aquatic organism due to human activity. As w as inform people how vital pH can affect an entire habitat and even ecosystem Our hypothesis was valid because we proved that testing Daphnia in a strong pH (three and five) and a strong acid (twelve) the survival rate of the Daphnia would drop, which did as the Daphnia continued to day from day to day as the e acids and bases caused it harm. The relationship between the Daphnia and the level of independent variable was seen as we put the Daphnia in different pHs and saw that died in different WA How to cite Data Analysis And Discussion Science Fair, Papers

Supply, Demand, and Price Elasticity free essay sample

Caused significant rises in rice prices. In late April 2008, Thailand announced a project, called the Organization of Rice Exporting Countries (OREC) with the potential to develop into a price-fixing cartel for rice. However, experts affirm the blame for higher rice prices was based on the weak U. S. dollar. It is determine that when the value of the dollar falls, the prices of internationally traded commodities, like gold and rice increase because more dollars are needed to purchase the same quantity of any commodity. Commodities are products consumers purchase more of when the price of the commodity lowers. If the price of the commodity were to increase then consumers would buy less. Rice is a commodity and consumers will adjust the amount bought depending on the price of rice. Rice is considered to be a Griffin good. Griffin goods are inferior goods which have an upward sloping demand curve. The income effect is greater than the substitution effect. Normally with inferior goods, the income effect will cause the consumers to demand less of a good. The substitution of rice as the cost decreases, are other foods which are not normally available to poor consumers. If the cost of rise is lower, the consumer buys less and pends his or her additional income on foods which are preferable but not as affordable (Hubbard, OBrien, 2010). Insulin, however, would not show the same results as rice. Insulin, as a necessity, would keep the same demand if the price lowered or increased. If the cost of insulin decreased then it is likely to see an income effect for other goods purchased by diabetic consumers. The consumer would in a sense, have an increase of income. If the cost of the insulin increased the consumer demand would still remain the same but would need to decrease the demand for other goods. Next time when we go to an Asian restaurant and decided to have a rice dish, stop for a second and think about these questions; is the current world supply enough to fulfill the demand? Is the supply of grain and corn affecting the current price? What will the price be if there are shortage of supply and surplus of demand and how that would affect the equilibrium point? Try to answer those questions like we did in this paper. It will help you gain more respect for the rice and appreciate its value and the effects it have on all of us.

Supply, Demand, and Price Elasticity BY dannyl 3140 Supply, Demand, and Price Elasticity Paper Rice. ECO / 212: Principle of Economics Week 2 Learning Team Assignment With the growing cultural diversity in the San Francisco bay area, it is hard not to otice the Asian cuisines and restaurants in every corner of the block. Asian food had become a natural substitution choice for the American fast food; and rice, is the perfect substitution for wheat and flour. Rice is the seed of the monocot plant Oryza sativa. As a cereal grain, it is the most important staple food for a large part of the worlds human population, especially in East and South Asia, the Middle East, Latin America, and the West Indies. It is the grain with the second-highest worldwide production after corn. In this paper, we will evaluate the cause and effects of rices upply, demand, price elasticity, and market equilibrium point. Some of the major rice providers, like Thailand and China supply the world with rice. In order for a place to grow rice, it would require a lot of water and moisture like humidity (Workman, Daniel). If that country were to encounter a drought, like a major heat wave, it would require more maintenance for the crop to grow. Also, it can destroy the crop making it non-harvestable. If a crop is non- harvestable, with the money put into it, it would be a 100% loss. More heat equals more water needed to keep the crop on its growth ycle and more maintenance equals more money in labor. The amount of investment has direct relationship to the price of the rice. If there is less rice harvested because of a drought, the less supply there will be. If the demand stays constant, then the shortage of supply will result in an increase in price. In the other hand, when there are surplus of supply and demand is constant, there will be a decrease in price. If the supply is constant and the demand is changing, the price will also be affected where more demand creates shortage, and less demand creates surplus. Shortage will increase the price, and surplus will decrease the price. In 2008 the price of rice was at a high of 24 cents per pound, which was twice the price that was a year before. When the price of rice rose, major rice exporters banned the export of rice to other parts of the world. These countries were nervous that the increase in price would cause the low-income residents to become angry. So they decided to keep most of the rice within their country and hope that would bring down or at least keep the price of rice stable (Bradsher, 2008). This kind of action influences the product market equilibrium where consumers expect to pay more due to lower supply and higher demand. When the government decides to set a price for the rice, the price floor is set above the market equilibrium. The price floor prevents the prices from being too low. The higher price will causes a decrease in demand, as some consumers will be look for another more affordable substitution in the same commodity. Another factor that causes the increase of rice price was due to a general upward trend in grain prices caused by droughts in major producing countries, particularly Australia. Although there are no shortages of rice on world markets the general upward trend in grain prices led to panic buying and government rice export sanctions. The

7 Most Common Mistakes on ACT Math How to Avoid Them

7 Most Common Mistakes on ACT Math How to Avoid Them SAT / ACT Prep Online Guides and Tips I've tutored many students on the ACT Math section, and they often found it frustrating. Some struggled because they considered themselves better English students and felt overwhelmed by the content and pacing of ACT Math. Others found that even though they considered themselves strong math students, they had a hard time getting the score they wanted in the ACT Math section. But allthese students typically madethe same types of mistakes. In this article, I’ll go over the seven most common mistakes students make on the ACT Math section and how to avoid them. Mistake #1: Skipping Steps ACT Math questions can be very sneaky.Problems can appear at first glance deceptively easy because they only require you to know basic math topics. However, the ACT questions ask for you to apply this basic knowledge in unique ways and often require you to run through several steps to get to the correct answer.If you don’t write out these steps, you can easilyend up with the wrong answer. For example, check out this ACT Math question: I’m going to admit that the first time I attempted this I got it wrong because I did not write down my steps!Hopefully, you’ll learn from my mistake.Together, we will write out the steps and get to the correct answer. There are 4 questions with 3 possible answers, and only 1 of the 3 answer choices will be correct. Therefore, for each question, Elliott has a ${1}/{3}$ chance of answering correctly.Since there are 4 questions, Elliot’s chances of answering all 4 correctly at random are$({1}/{3})({1}/{3})({1}/{3})({1}/{3})$which equals ${1}/{81}$, so the correct answer is E. Initially, I tried to do this problem in my head without writing any steps down. Because I didn't write anythingdown, Imistakenly thought there were four possible answer choices for each question instead of three. Therefore, I got the wrong answer, ${1}/{256}$. Thankfully, my answer wasn't one of the answer choices, so I caught my mistake, but I would have missed the questionotherwise. Don’t miss problems because you didn’t write out all of the steps.This is arguably the easiest mistake to fix.All you need to do is write out all your steps, and you’ll never accidentally miss a problem because you skipped a step!Learn from my silly mistake! Mistake #2: Forgetting Formulas The ACT doesn’t give you any formulas.However, you’ll need to use a lot of formulas to answer questions in the ACT Math section.You need to know these math formulas to answer the questions correctly.We’ve compiled a complete list of all the formulas you need to know for ACT Math. You need to memorize these formulas.Create flashcards to help you memorize.I cannot stress enough how important memorizing formulas is.You’ll see at least 10 questions (out of 60) on the ACT Math section that you will not be able to answer without knowing formulas. Check out this ACT Math question that you couldn’t answer without knowing the formula: If you didn't have yourtrigonometry formulas memorized (SOHCAHTOA), you would have no idea how to answer this question. It's impossible to answer this question without knowing the formula for the tangent of an angle since that is the value you're trying to find. If you remember your trigonometry formulas, you know that the tangent of an angle is the opposite/adjacent.For this question, you need to find the tangent of angle B.The adjacent side for angle B is 2, which means it is our denominator.This means we can eliminate answer choices H, J, and K. However, you cannot find the final answer without also knowing the formula for thePythagorean Theorem.You need to know the Pythagorean Theorem in order to find the measureof the missing side of the triangle, the opposite side to angle B. Using the Pythagorean Theorem, you can find this missing side measure. $$a^2+b^2=c^2$$ $$a^2+2^2=5^2$$ $$a^2+4=25$$ $$a^2=21$$ $$a=√{21}$$ The opposite side will be $√{21}$, and we know that our adjacent side is 2. The final answer is F, ${√{21}}/{2}$. Mistake #3: Not UnderstandingFunctions Functions tend to be one of the hardest concepts, if not the hardest concept, for most students. Students are usually less familiar with algebraic and/or trigonometric functions than they are with other math concepts such as fractions and percentages. Some students have completely forgotten functions or never learned them in the first place. To master the ACT math section, you need to be a whiz at functions. See this ACT Math function question: To answer this question, you need to know the rules of trigonometric functions andtranslations. You will not be able to answer this question without knowing these rules. You first need to use your knowledge of trigonometric functions to read the graph, and then, you need to apply your knowledge of translations rules to find the final answer. First, you need to be able to identify which function is $sin(x)$ and which is$sin(x+a)+b$ on the graph since they're not identified for you.If you know your trigonometric functions, you know that the y-intercept of$sin(x)$ is 0, meaning the graph of$sin(x)$ crosses through the origin. Therefore, the other functionmust be$sin(x+a)+b$. Once you've correctly identified which function is which, you need to figure out how$y=sin(x)$ was changed to make$y=sin(x+a)+b$, which is where your translation knowledge comes in. Based on the given information in the question, you know the two have the same maximum values, meaning the amplitude was not changed.By looking at the graph you can tell$y=sin(x)$ was shiftedto the left or right to make$y=sin(x+a)+b$, but it was not moved up or down. Since there was no up or down movement, b must equal zero since any change in b would cause$y=sin(x)$ to move up or down. Therefore, the answer must be A, but let's check by figuring out what a should be. Because$y=sin(x)$ repeats itself infinitely, you can shift it either to the left or right to create the new function$y=sin(x+a)+0$.Therefore, $a$ could be positive or negative (for example, ${-3Ï€}/{2}$ or ${Ï€}/{2}$, but it could not equal zero, so A is the correct answer. If you've forgotten functions, then you need to review. You must review all math concepts that you’re rusty on in order to succeed on ACT Math.Lucky for you, we’ve written specific ACT Math content guides to help you study any individual ACT Math content area that you might be struggling with, fromtrigonometric functions totranslations,ratios to rotations, points to probabilities and much more. Mistake #4:Panicking at Unfamiliar Question Formats The ACT sometimes asks questions in strange ways, which can scare a lot of students. I had many students who, even though they'd reviewed all of the math content areas, wouldread the question and rather than trying to figure it out would just freak out and give up. The question below is one that presents an unfamiliar question format. You’ll likely recognize it as an algebra question, and if you were asked to find the solutions forx (had you been given numerical values of m and n), you’d likely know how to answer that question.However, instead, this question tells you the valueof x and asks you to figure out what m and n are. Let’s work through this problem together: If the only possible solution for x is -3, that means the given equation can also be represented as $(x-y)^2=0$.We need to figure out what y is in order to find out what m and n are. If $(x-y)^2=0$, then you can separate it into $(x-y)(x-y)=0$.For this to be true, x-y has to equal 0. $$x-y=0$$ The question told us that the only solution for x is -3, so we plug that in and solve: $$-3-y=0$$ $$-y=3$$ $$y=-3$$ Now that we know the value of y, we plug it back into $(x-y)^2=0$ and then multiply and simplify to figure out what m and n are: $$(x-(-3))^2=0$$ $$(x+3)^2=0$$ $$(x+3)(x+3)=0$$ $$x^2+3x+3x+9=0$$ $$x^2+6x+9=0$$ Therefore, $m=6$, so the answer is C. There is no easy solution to this type of mistake.The only way to learn from this mistake is with practice.ACT Math questions are unlike the math questions you usually see in math class. They are much trickier. I recommend taking as many practice ACT testsas you can in order to get used to the style of ACT math questions.You need to train yourself to be able to solve math questions in this new way. Mistake #5: Solving for the Wrong Value As I just said, ACT Math questions can be tricky.They are tricky not only because they ask you to apply basic skills in new ways but also because they sometimes phrase questions in weird, convoluted ways. Althoughthe ACT is often called the more straightforward test in comparison to the SAT (or at least in comparison to the old SAT),some ACT Math questions are far from straightforward.Take for example this question: The question is basically asking how the surface area will change if you double the length, width and height.However, if you misread the question, you could easilyjump to the incorrect conclusion that the surface area was doubled, and the answer is A. Given the formula for surface area, $A=2lw+2lh+2wh$, if we double $l$, $w$, $h$, the new surface area would be $$SA=2(2l)(2w)+2(2l)(2h)+2(2w)(2h)$$ $$SA=2(4lw)+2(4lh)+2(4h)$$ That can be written as $$SA=4(2lw+2lh+2wh)$$ When that is compared to the original $SA=2lw+2lh+2wh$, you can see it’s 4 times the original, so the answer is B. Take your time.I know you don’t have a lot of time on the ACT Math section, but you need to read each question completely and make sure that you know what you’re being asked.The ACT Math section will always throw you an answer choice that will seem correct if you misread the question.They are trying to tempt you to answer incorrectly.Don’t fall for it! Mistake #6: Incorrectly Using Your Calculator You need to be careful with your calculator.It’s a great tool, but to quote the Spiderman comics, â€Å"With great power comes great responsibility.†It’s very easy to feel rushed during the ACT Math questions, and, in your hurry to find the answer, you type the wrong number(s) into your calculator and, therefore, come to the wrong answer. Now, this is typically one of the better mistakes to make on this list because if you type in the wrong number(s) you’ll likely find no matching answer in the ACT answer choices, and you’ll realize you made a mistake. However, you don’t want to be making this mistake.Even if you catch your mistake because there is no matching answer choice, you’ve still cost yourself valuable time that you could have been using to answer another question.Take the time to check that you’ve copied the numbers into your calculator correctly. Type carefully! Mistake #7: Not Pacing Yourself With only 60 minutes to answer 60 questions, you need to learn to pace yourself. To determineyour pacing, you need to first figure out your target score. The questions progress from easy to hard, so no matter what score you're aiming for always attempt the questions chronologically. If you're aiming for a score higher than 30, then you're going to need to answer all or almost all of the 60 questions. That means you must spend under 1 minute per question on the first 30 questions to save time for the harder end questions. If you're aiming for a score below 30, then you can afford to skip some questions. Determine how many questions you need to answer to reach your score and then pace according to that amount of questions. For example, if you're aiming for 20, then you only need to get 32 math questions right. You can allow yourself a minute and a half per question, and you should attempt the first 40-45 questions and skip the hardest ones at the end. Simply choose a random letter and bubble that in for the ones you skip, since there is no penalty for guessing. I won’t go into detail because we have another great guide on how to stop running out of time on ACT Math and how to take advantage of the easy to hard question order. However, I will say to truly master the pacing you need to take many practice tests under realistic conditions.Don’t give yourself even one extra minute on your practice tests because this can artificially inflate your score. Stick to 60 minutes for the ACT Math section. What’s Next?

Singapore Economic Essays

Singapore Economic Essays Singapore Economic Essay Singapore Economic Essay Economic Stability Economic stability is a necessity in any country considering the benefits associated with it. In this case study, there have been several factors pointed as the core courses of the economic instability in Singapore. Thus, there is a need for recommendation strategies that can be applied to contain these causes of economic fallout specifically, which should be a responsibility of the Singapore government. Firstly, the government should support the economic growth via encouraging productive capacity. In this sense, the Singapore quality and productivity level of the current labor force, especially in the manufacturing sector, will guarantee boost of the economic and social infrastructure platforms. As a result, the global competitiveness of Singapore is warranted. Economic Challenges Also, although there are reported cases of inflation, the government should consider targeting the whole economy and not dealing with inflation as a single factor. In this sense, the policies that the Singapore government will put in place should be the ones that aim at increasing domestic product before inflation. Hence, this would result in nominal GDP targeting, and subsequently, the economy will be a safe path. Such incentive will cause an expectation to the investors and also consumers of high inflation rates, which they will be likely prepared and consequently forming an encouragement to invest today rather than a future date. Other recommendations that I think are at the disposal of the Singapore government include; implementing fiscal policies that are workable enough to improve the economic state of the country, increase the labor skills of the workers in the various sectors via the use of government subsidies and creation of wage credit scheme and PIC schemes. If all the above recommendations are appropriately implemented, I believe that these economic challenges facing Singapore will be mitigated.

Management Essay Example | Topics and Well Written Essays - 750 words - 14

Management - Essay Example epartment should analyse and integrate the current processes and also the processes like recruitment, retention, employee development, leadership development, performance management systems, workforce planning, business culture etc. Recruitment is the process of placing right people at the right place at the right time whereas retention is the process of retaining the employees with the help of rewards and supporting systems. Employee development means the process of giving proper training to the employees whereas leadership development is the program for developing leadership skills among employees. Performance management systems collect the feedbacks about the employee performances and take appropriate strategies to sustain or improve it. Workforce planning is the effective utilization of the existing manpower and business culture is presenting a positive way of performing. Performance management systems are important both for the employer and the employee. If the employee feels that his performances were taken seriously by the organization, then he will improve his productivity and subsequently the organization will also benefit from that. A well defined performance management system may have elements of employee development, salary review, personal performance and business performance. Organizations can save a substantial amount of money retaining the employees and improving the performances of the employees. Talent management plan can also attract employees from outside also and more over it can help the organization in identifying the type of employees needed, areas needed to be improved and fine tuning of the business philosophies based on the changing trends. Thus both Performance Management System and Talent Management plan can work hand in hand to improve the overall productivity of an organization. The above article has strengthened my understanding about the necessity of performance management and talent management systems in organization. Even

Corporate social responsibility and ethical dilemmas Essay

Corporate social responsibility and ethical dilemmas - Essay Example When organizations are hiring employees, they tend to be concerned on the capability of the employees to follow the company ethics and values. This is because company ethics and values are crucial in decision-making. Managers are concerned with overseeing the day-to-day running of an organization. They are thus required to possess adequate skills on the ethics that characterize local national and global societies. In the recent past, globalization has resulted in increased competitiveness in the corporate sector and change of production from national level to a global one by most companies. With globalization, the corporate sector is increasingly becoming vulnerable to global forces. This has resulted in numerous challenges in corporations, which managers are required to address. Additionally, people and organization have become more concerned and interested in business ethics. This section will focus on the ethical and value challenges that face individuals working in financial sect ors in companies and financial institutions. Additionally, the paper will analyze how the challenges can aid employees in the financial profession to meet their goal of enhancing responsible business operations. ... Actually, there has been increased awareness on business ethics requiring companies to be more vigilant in their operations. Traditionally, companies focused on making profits since theories such as the one suggested by Friedman argued that the sole responsibility of a firm is to increase the shareholders’ value. However, this notion has been changing due to the need for sustainable responsible business (Burchell 2008; Cameron 2002). Ethical issues that may arise in the financial organization are likely to affect all the stakeholders. This is because all stakeholders depend on financial services directly or indirectly. Personal and corporate ethics are a common source of dilemma for professions working in financial management. This is because of the challenges emanating from conflict that may arise due to disparity in personal ethical values and organizational ethics (Klempner 2009). Ethics are fundamental in financial management since they ensure that financial managers are h onest while dealing with financial situation. My career as a financial manager will require me to be honest. Ethics are crucial since finances are closely intertwined with people. One major ethical issue facing banks regards the method to compensate sales driven planners as well as planners. The dilemma is on whether to use commission or fees. Some compensation strategies often result in exploitation of the investor. Whichever the strategy of compensation used leads to ethical issues since the planners have to subordinate their benefits to those of the customers. This ethical issues results in swaying of planners. A good example of a bank that has benefited from corporate social responsibility is Scotiabank. This bank has

Budgeting Essay Example | Topics and Well Written Essays - 750 words - 2

Budgeting - Essay Example Robert Worley, a criminal justice professor at Texas pointed out that cutting prison’s amenities would have staggering impacts on the way everything would run in the prison system (Jennings, 2011). Based on the report Worley emphasized that a well fed and inmate that is happy for instance is the one that would have more positive drive to cooperate, making it easy on the part of the prison administrator to manage everything as smooth as possible. The federal government and specifically the states wrestle with the country’s challenging economic times and the criminal justice system has evidently struggled to create the necessary adjustment, so as not to compromise the standard quality service in ensuring the maximum safety of the society (Justice Policy Institute, 2013). One particular initiative in order to maximize the chance of survival is to consider allocating the right budget plan for the associated cost of incarceration. Policies are trying to balance everything, c reating a way and meeting halfway the relevant needs of every concern. Although it is not an assurance that all needs will be well considered, the government is trying to create the most efficient way on how to implement the allocated budget for the prison system without trying to create a high value for discontentment. The above report is of important consideration because it concerns many significant issues. One particular point is the issue about savings and the associated changes with this initiative. This means the government has to understand the value of sacrifice and the advantages and disadvantages linked up with it. It is a matter of understanding whether the associated costs would be far below the advantages to be generated. In the present time by which the US economic standing is currently recuperating, it is definitely hard to keep everything in order just as the way when everything from the past would run smoothly for everyone. Another significant concern is the idea o n how to implement the budget without creating a substantial impact on the entire prison system in Texas. This is a way too hard to employ as some prison experts and advocates would try to promote the idea of humanitarian cause. For instance, Worley tries to point out the idea of small changes and turnover concerns. In issues like this, it is therefore important to come up with a remarkable basis and to weigh things as remarkably as possible for the benefit of everyone and not only for the chosen few. The issue of budget cuts in the prison system is very controversial as there are other relevant issues that could relate in it that in the long run would also create some necessary impacts on the society. The article tries to conclude the report by showing the amount already set up for budget implementation and the associated savings that were generated so far. In other words, the author tried to showcase both sides of the coin and fairly have given the readers the opportunity to asses s the government’s prevailing initiative concerning the associated financial management in the prison system particularly in the state of Texas. Furthermore, the readers would have a better way to grasp the relationships between the small changes and turnover concerns. The author was trying to give us a clear perspective so as to direct us to the appropriate and necessary things to do. The ongoing move to go for budget cuts in th
